Tacx NEO 2T Smart Trainer In-Depth Review

DSC_5994

It’s been just over two months since Tacx announced their NEO 2T smart trainer, the latest in the line of high-end NEO trainers. You may remember back in my launch post, it wasn’t all sunshine and unicorns for the new trainer. It, like many trainers in this 2019 indoor training season of new devices, lacked the accuracy I’d expect – especially from a top-end unit. I basically said don’t buy it yet.

So Tacx has spent a fair bit of that time working and re-working the firmware, and I think they’re finally in a relatively good spot – the point where I’ve got no issues recommending the trainer. Of course, like always, and for any product, I’ll nitpick a few things that could be improved. But on the whole I’m happy to be using this unit for my rides lately.

In this review I’ll dig into what’s changed (and whether it’s worth an upgrade or skipping a good sale on older versions), as well as all the usual details around how well the trainer works with apps, accuracy, and everything else you could possibly ask. Plus, I’ve had the advantage of some DCR Reader feedback over the past few weeks as the NEO 2T is already shipping.

Oh, and finally, as always I use devices like wilderness trails – leave nothing behind. These are media loaner units that go back to Tacx shortly. You can help support the site here by checking out the links at the end of the post (it’s already shipping/available). Doing so makes you awesome.

What’s Different:

The vast majority of the changes to the Tacx NEO 2T are internal, not external. In fact, the only external change you’ll notice is a new ‘racing stripe’ inset on the back panel of the folding NEO wing. Here you can see it next to the Tacx NEO 1 and Tacx NEO 2:

DSC_6099

(Left to right: Tacx NEO 1, Tacx NEO 2, Tacx NEO 2T)

But wait, before we get there, some super quick stat basics – just in case you’re not familiar:

– Direct drive trainer: This means you remove your rear wheel
– Flywheel: It has a virtual flywheel up to 125kg, the largest of any trainer on the market.
– Downhill Drive: This is one of only a handful of trainers that drives the rear ‘wheel’ forward while going down hills, thus simulating descending inertia.
– Cassette: No Tacx trainers include a cassette, which will set you back $50-$60, plus $10-$20 in tools to install.
– Sound: Identical to the original NEO, essentially silent. Only the sound of your drivetrain is heard, and a very faint hum of internal fans/electronics.
– Handle and Folding: This unit lacks a handle, which continues to make it slightly awkward to move around. It does have foldable legs though for easy storage.
– Protocol Compatibility: ANT+ FE-C, ANT+ Power, Bluetooth Smart Trainer Control, Bluetooth Smart Power
– App Compatibility: Every app out there basically (Zwift, TrainerRoad, Rouvy, Road Grand Tours, SufferFest, Kinomap, etc…)
– Skewer Compatibility: All the skewers and adapters you could ask for: Road 130mm, MTB 135mm, 142x12mm, 148x12mm
– Max Incline: 25% simulated grade, the highest of any trainer out there
– Max Wattage: 2,200 watts resistance
– Stated Accuracy: < +/-1%
– Power Cable Required: No, it can operate powered or standalone sans-power.
– Pricing and Availability: $1,399/€1,299/£1,199 Shipping Already

Now – as for the changes, like they teach you in grade school, it’s what’s inside that matters most. And in this case what matters most is magnets. The company has made a pile of changes internally around the magnets. It’s magnet mania. Here’s what’s different inside at a geeky level:

– Stronger Magnets: This gives it the higher torque that eliminates the slip for the vast majority of riders (including myself)
– Thicker Wiring: This reduces the heat output and improves efficiency
– Changing Wiring Topology: This reduces vibrations but also reduces the sensitivity of manufacturing tolerances
– Skewing of Magnets: This reduces vibrations and sounds
– New Magnet Holder: This helps in manufacturing by increasing position accuracy, but also reduces vibrations

Like I said, it’s magnet mania.

What does that all mean in real-life? Well, we’ll get to that in the First Rides section. But first, let’s look at a graph, since again, geeky. This shows you the braking power of the Tacx NEO 2T versus the NEO2, against your speed. This shows why you could cause ‘slip’ at low speeds on the NEO2, as it’s more than tripled in those lower scenarios. Some people can apparently still cause it to slip, but they’d be pretty powerful folks. I can’t do it with my power output (up to 1,000w roughly). It’s not a straight wattage thing, but really slow-speed sprints. More on it later.

But beyond all this magnet mania, there’s a few practical considerations. First, it’s quieter. At least in theory, frankly – I can’t tell the difference in my studio. Maybe if I move the whole setup to the podcast recording room with the soundproofing now installed on the walls I’ll be able to hear it.

The other change coming, but not yet in any firmware, is Cycling Dynamics. That’ll give us access to the typical Cycling Dynamics suite of data, though I haven’t tried it yet to see if all the metrics are carried through, or how it stacks up against Garmin Vector 3. After all, those two should match in my mind. So I’m keen to see how that looks. And for that matter, how it might stack up against Favero Assioma and their recent Cycling Dynamics update as well.

So, to spoil the rest of the post – would you upgrade an existing NEO trainer? Probably not. Unless that tiny bit of slip really bothers you, I’d keep what I’d got from a NEO trainer standpoint if I already had one. And to that same extent, you’ll see some occasional sales on the existing Tacx NEO 2 units that came out last year – those are awesome as well, and will be getting the Cycling Dynamics update too. So again, go forth. for the right price.

What’s in the box:

DSC_5981

Those astute Tacx unboxing geeks out there, you might notice the tiny change in wording to the lower right corner of the box: ‘Tacx: A Garmin Company’. Beyond that, it’s basically the same rough design as last year’s NEO 2 box.

DSC_5984

Once you crack it open, you’ll find a skewer and thru-axle adapters, as well as some paper stuff and a portion of the power cord.

DSC_5987

Remove the top layer and you’ve got yourself the trainer folded up inside, as well as the brown box somewhere down there with the remainder of the power cord.

DSC_5990

Additionally, you’ll find a front wheel block for keeping your wheel slightly elevated and straight.  Here’s all the pieces laid out:

DSC_5993

You can then unfold the trainer to its full and majestically tall height. Seriously, this thing towers over every trainer out there like some dark Star Wars overlord that it is:

DSC_5999

Here’s a closer look at the back of that power cable. I include this picture not for you, but for me. So in a year when I’m trying to figure out which power cable is which, I can find this picture and remember.

DSC_6004

When I’m less lazy, I usually cut out a piece of the paper envelope stuffs and tape it to the power adapter, so I know that it’s the Tacx NEO 2T. Right now I’m lazy – it’s almost coffee time and I’m gonna need it to make it through this review before I gotta get going.

Beyond attaching the cassette as we’ll discuss in about 6.2 seconds, there’s no assembly required for the NEO 2T.

The Basics & Setup:

DSC_4681

All roads on almost all trainers start with adding a cassette. Unless you’ve got a KICKR 2018 or Elite Suito that is. But since this isn’t that review, we’re back in cassette land. So, you’ll need to pickup the right type of cassette for your bike.

I typically buy Shimano Ultegra cassettes for my trainers (mostly for sound-testing consistency across videos), but I’ve also done a few SRAM ones and whatever else happens to be on sale from the bike shop. It generally doesn’t matter, except sometimes you’ll find some of the lower end cassettes (like a Shimano 105) don’t quite sound as quiet as mid to higher-end ones. If you’ve got a new SRAM AXS bike, you’ll also need to get a different freehub adapter from Tacx as well. But since you just spent a boatload of money on that bike, spending more money will feel natural to you.

DSC_6011

In any case, with a cassette, you’ll need two tools. A lockring tool (or lockring + a wrench, in my case), and a chain whip. In this case, you need the chain whip since you can’t get a good grasp on the flywheel.

DSC_6013

Once you’ve got the cassette on, simply put in place either the quick release skewer or thru-axle adapter (depending on your particular bike). The unit includes a thru-axle adapter set for 142x12mm & 148x12mm.

DSC_6019 DSC_6021

Once that’s done you’ll want to go ahead and plug it in:

DSC_6005

Now, technically speaking you don’t have to plug it in. You can use it in the middle of a race warm-up area sans power plug just fine. The only thing you’ll lose is the ‘downhill drive’ capability, which spins the wheel forward when you descend down hills (to mimic how it works for the bike in real life).  The power adapter/cord is 120/240v, so you can use it anywhere in the world if you happen to travel with it.

Also, I find that pairing is a tiny bit easier since the unit will go to sleep without a power cable. Of course, you need to only spin the cranks a few times and you’re back in business. Meanwhile, on the left side of the unit you’ll find the status lights. These are for general power, then one for ANT+ & Bluetooth Smart connectivity.

DSC_6007

After you’ve mounted your bike, you can also slide that front wheel-block under there as well.

DSC_6023

With that, we’re ready to roll. Now, we’ll get to app compatibility in a moment, but first let’s start with the road feel. Like I always say – for me personally, it’s hard to separate the fact that I’m riding indoors from outdoors. It’s still a trainer, and I’m still looking at a wall in front of me.  My brain can only turn off so much of that.  Still, much of the road-like feel is driven by the flywheel, and be it physical or virtual, flywheel sizes tend to be measured in weight.  This impacts inertia and how it feels – primarily when you accelerate or otherwise change acceleration (such as briefly coasting).

All that prefacing done, the Tacx NEO 2T ranks pretty darn high up there in the inertia replication standings. In the same ballpark of the CycleOps Hammer 3 & Wahoo KICKR 2018. As I’ve noted many times, my bet is that you could put different blindfolded people on different units and they’d all say totally different things on which one they felt best. Even cycling journalists. Some days I think the KICKR feels best, some days I think the NEO feels best. I suspect it’s even as nuanced as which exact gearing I’m in.

DSC_6034

Now given the NEO 2T is a smart trainer, it’ll change resistance automatically in a few different ways, primarily driven by different applications/methods.  But most of this all boils down to two core methods:

ERG Mode: Setting a specific power level – i.e., 210w.  In this mode, no matter what gearing you use, the trainer will simply stay at 210w (or whatever you set it to).
Simulation Mode: Simulating a specific outdoor grade – i.e., 9% incline. In this mode, it’s just like outdoors in that you can change your gearing to make it easier or harder.  Wattage is not hard-set, only incline levels.

In the case of simulation (aka slope) mode, the Tacx NEO 2T can simulate from 0% to 25% incline – which is frankly way more than your legs ever want to deal with. It’s also the most of any consumer smart trainer. The Wahoo KICKR & Saris H3 top out at 20%, and the Elite Drivo at 24%.

The second mode the trainer has is ERG mode.  In that case, the company claims up to 2,2200w of resistance at 40KPH. Although, realistically, you don’t care about that. I can only barely (maybe) break 1,000w for a second or two, and even most front of the non-pro pack cyclists aren’t going to top 1,800w.  The pros would only be just a bit beyond that.  Said differently: Peak numbers don’t matter.  Instead, what matters is actually a harder metric to make clear – which is the ability to simulate high grades and lower speeds (especially if you’re a heavier cyclist).

One core test I do with all trainers though is responsiveness: How quickly does it respond to ERG mode changes? I typically do that with my 30×30 test via TrainerRoad, though it doesn’t really matter what method you use as long as you’re looking at big shifts in wattage:

IMG_1133

In this case, the Tacx NEO 2T responded exceedingly fast. In fact, I’ve argued for a bit now that it responds too harshly (due to the extra power). Meaning, it’s too good at its job and it feels like running into a brick wall for these types of big shifts in power. Still, that’s more of a personal opinion than anything. What’s more objectively graded is how precisely it hits that shift in power (which is different than power accuracy). In this case, it overshoots slightly for these intervals, depending on how careful I am in gearing.

For example, these intervals were all at 404w, so in theory I’d expect that first second (just one second) to be in the ~400-410w ballpark, but the NEO 2T slightly overshoots each time for the first second to about ~420w. This is, however, a big improvement over back in August, when it was overshooting to 455-460w. To be fair, most trainers do some aspect of overshoot. The KICKR does it too (even more than this). So perhaps this is me slowly but surely demanding more and more as time goes on from these companies at these price points. After all, the Saris H3 nails this nicely (albeit, has other quirks instead). Don’t get me wrong, for most people, you won’t notice. I’m just not most people (you would have noticed back in August though, that hurts).

Next, there’s two non-ERG mode features that are worthwhile noting. The first is road feel. This was introduced a few years back on the Tacx NEO 1 unit and continues forward to the NEO 2 and NEO 2T.  This functionality enables the trainer to replicate the feel of the roads as you ride them in the game. Cobblestones will feel like riding on cobblestones. Planks on a boardwalk will feel just like an actual boardwalk. It really is fascinating – and has been a draw for the Neo series since it came out:

2019-11-07 17.21.55

Now, there’s not a ton of training benefit here, per se. But that’s true of many things we do on trainers indoors. If it was all about training benefit we’d just be riding in ERG mode every day on perfectly structured workouts. Instead, we have a wide variety of apps that by and large are designed to keep us entertained.  And this feature simply adds to that entertainment factor. For me, it’s a nice change mid-way through a route on Zwift to feel the wooden planks of the piers.  No other trainer offers that today.

Now’s probably a good time to talk sound. In short, it makes virtually no sound. About the only sound you’re going to likely hear is that of your bike’s own drivechain (meaning, the chain and such). The unit itself does have a fan, but it’s roughly akin to a fan found on a small computer. To demonstrate this, here’s a simple audio test clip:

Next, the NEO 2T has downhill drive simulation, which means that as you go downhill the trainer will forward spin the rear ‘wheel’ (cassette and flywheel since there is no wheel). This means that the trainer will simulate the inertia of going downhill.  This is yet another little touch that makes things feel more realistic than they are.

Next, while Tacx does have a mobile app for their trainer, it’s unlikely you’re going to use it much if you use other 3rd party software.  However, it is valuable for setting your correct weight so that you can get realistic grade simulation (as well as firmware updates). This is notable if you’ve got multiple people in your household at dramatically different weights:

2019-11-07 17.18.13 2019-11-07 17.18.36

The app also allows you to test out the road feel and ISOKINETIC/ISOTONIC options. You can see below in the two side by side shows a handful of the many different road feel modes I just talked about up above.

2019-11-07 17.18.45 2019-11-07 17.18.55 2019-11-07 17.19.00

The app is also where you’ll update the firmware from time to time:

IMG_2311 IMG_2312 IMG_2315

Oh, wait – one more super important feature. It can produce a disco party. Yup, as you pedal harder the lights below the unit will shift in colors from a blue to purple to eventual red coloring. The harder you pedal, the more vibrantly red it gets.

IMG_1942

Kinda neat. No training benefit, except that my wife can look over and visually see when I’m just wimping out.

App Compatibility:

2019-08-18 11.01.12

The Tacx NEO 2T follows most of the industry app compatibility standards as previous Tacx products, and essentially follows the industry norms as you’d expect from a high-end trainer.  As you probably know, apps like Zwift, TrainerRoad, Sufferfest, Rouvy, Kinomap and many more, all support most of these industry standards, making it easy to use whatever app you’d like.  If trainers or apps don’t support these standards, then it makes it far more difficult for you as the end user.

In the case of the NEO 2T, it (like Wahoo) doesn’t quite adhere to everything. Specifically around Bluetooth Smart FMTS compatibility, which is trainer control. In the case of both, they dance to their own protocols. Tacx actually does support FTMS on all their non-NEO series just fine, but doesn’t do FTMS on the NEO series due to FTMS’s lack of ability to transmit weight information to apps (which is needed for the virtual flywheel in this specific trainer series).

Practically speaking that has little effect for the major apps, but does impact smaller apps. Zwift, TrainerRoad, etc… all support the proprietary versions (since they were using those versions well before FTMS existed). But newer and smaller apps like Xert, for example, have focused on supporting the standards instead, rather than spinning their (virtual) wheels on proprietary development. Tacx had previously promised FTMS support a year ago, but it’s not here yet for the NEO series. Again, for the majors – no biggie, but maybe an issue for your specific app – so double-check that.

The unit supports the following protocols and transmission standards:

ANT+ FE-C Control: This is for controlling the trainer via ANT+ from apps and head units (with cadence/power data). Read tons about it here.
ANT+ Power Meter Profile: This broadcasts as a standard ANT+ power meter, with cadence data
ANT+ Advanced Power Meter Metrics: This includes pedal smoothness and left/right balance, and later this year Cycling Dynamics as well.
ANT+ Speed/Cadence Profile: This broadcasts your speed and cadence as a standard ANT+ Speed/Cadence combo sensor
Bluetooth Smart Trainer Control (Tacx variant): This is for controlling the trainer over Bluetooth Smart from a variety of apps.
Bluetooth Smart Power Meter Profile: This broadcasts as a standard BLE power meter, with cadence data
Bluetooth Smart Speed/Cadence Profile: This broadcasts your speed and cadence as a standard BLE combo Speed/Cadence sensor

In the above, you’ll note there’s cadence data baked into the various streams. That’s handy if you’re connecting to Zwift on an Apple TV, due to Apple TV’s two concurrent Bluetooth Smart sensor limitation (plus the Apple TV remote).  This means you can pair the trainer and get power/cadence/control, while also pairing up a heart rate strap.

For me, in my testing, I used Zwift and TrainerRoad as my two main apps (which are the two main apps I use personally).  In the case of Zwift, I used it in regular riding mode (non-workout mode, aka SIM mode), whereas in the case of TrainerRoad I used it in a structured workout mode (ERG mode). I dig into the nuances of these both within the power accuracy section. In addition, I used The Sufferfest and Kinomap too for some random days.

Starting with Zwift, you can see the Tacx NEO 2T listed as not just a controllable trainer, but also within the regular power meter and cadence section. You’ll want to pair it up as a controllable trainer (which will also pair it as a power meter):

IMG_1928

And then you can manually select the cadence signal. In every review, I keep wondering when Zwift will simply auto-select this as well, but it still doesn’t do it. All the trainer companies name everything the same, so it’s a trivial exercise to search for this.

You’ll see the trainer enumerated in a fairly similar manner on TrainerRoad as well:

IMG_1127 IMG_1128

Also, TrainerRoad’s tips page on using smart trainers in ERG mode:

IMG_1122

I’d *strongly* recommend you either read that page, or just simply just do one thing:

1) Ensure you’re using the small ring up front: This is for ERG mode specifically, shift into the small ring to get better control

Now the Tacx NEO 2T (like the rest of the Tacx NEO series), doesn’t support any type of calibration. Nor does it need it, in fact, you can’t even do a calibration if you wanted to. Though, some apps don’t exactly realize this yet, so you might see it listed on some apps.

Finally, to continue the spice of life – here’s the NEO 2T paired today over lunch within The Sufferfest. you can see it showing as the power meter, cadence sensor, and also the setting for ERG mode.

2019-11-07 12.38.53

Now, it’s worthwhile noting that Tacx on the NEO 2T not only transmits left/right balance (we’ll discuss accuracy of that later), but also some of the advanced power meter metrics like pedal smoothness. And Tacx says later this year, they’ll start doing Cycling Dynamics (the ANT+ standard variant). While one might assume this was purely a result of the Garmin acquisition, the reality is that Tacx had been considering this for a year now, well before Garmin came around and bought them out last February.

As for the current pedaling metrics, you can see those here on Garmin Connect:

image

Note that the app has to support those. So for example, if you use it with Zwift, they don’t support recording any of that data. In my case, the above was recorded with an Edge 520 Plus.

Power Accuracy Analysis:

DSC_6025

As usual, I put the trainer up against a number of power meters to see how well it handled everything from resistance control accuracy, to speed of change, to any other weird quirks along the way.

In my case I used one primary bike setup as follows in a bunch of configurations. I was kinda all over the place the last few weeks:

Canyon Bike Setup #1: Garmin Vector 3 pedals (dual-sided), 4iiii Precision Podium (dual-sided)
Canyon Bike Setup #2: Garmin Vector 3 pedals (dual-sided), Quarq DZero
Canyon Bike Setup #3: PowerTap P2 pedals (dual-sided), Quarq DZero
Giant Bike Setup #1: Garmin Vector 3 pedals, Stages LR (dual-sided)

This is all in addition to the trainer itself.  Note that because you remove the rear wheel I can’t use something like a PowerTap hub to compare as well (which I would use in power meter testing normally).

In my case, I was looking to see how it reacted in two core apps: Zwift and TrainerRoad (Bluetooth Smart on Apple TV and iPad), but I also did some work with Kinomap and The Sufferfest on iPad – so there’s that for you. The actual apps don’t typically much matter, but rather the use cases are different.  In Zwift and Kinomap you get variability by having the road incline change and by being able to instantly sprint (aka SIM mode).  This reaction time and accuracy are both tested here.  Whereas in TrainerRoad and The Sufferfest I’m looking at its ability to hold a specific wattage very precisely, and to then change wattages instantly in a repeatable way (ERG mode).  There’s no better test of that than 30×30 repeats (30-seconds at a high resistance, followed by 30-seconds at an easy resistance).

There’s two ways to look at this.  First is how quickly it responds to the commands of the application.  So for that, we need to actually look at the overlay from TrainerRoad showing when it sent the command followed by when the NEO 2T achieved that level. You might remember back in August when the unit came out I was displeased with two elements of this specific scenario:

A) The actual accuracy of the power
B) The inability for it to correctly nail the initial target power (it would previously over-commit by 50w).

So, two months and a flurry of firmware updates later, was it fixed?

Here’s the levels being sent (the blue block) by TrainerRoad (in this case via Bluetooth Smart on iPad) and how quickly the 2T responded to it.

IMG_1133

As I said up above, for the most part responsiveness per se isn’t an issue. It’s really good at that – too good I’d argue (too fast, too hard). What we can quibble about is the slight overshoots. But I’ve gone back and looked at about 3 years of data of me doing this test, and this is actually pretty solid comparative to most others (with really the Hammer 3 beating it in terms of precision).

But let’s shift our focus to power meter accuracy. That’s what this section is all about. Now technically speaking there isn’t exactly a power meter in the NEO series per se. Not in the traditional sense anyway. But that’s fine. Very few trainers these days have power meters in them – and there’s a long history of trainers with power meters actually performing worse in certain situations (and equally, performing great in others). What I ultimately care about is one thing: Is it accurate. I don’t care how you (a trainer company) achieve it. Power meter, no power meter, math magic, small elves…I don’t care. Nobody need care. Just get it right.

So, let’s look at the underlying data from that set. This was against a pair of PowerTap P2 pedals, the Quarq DZero, and the Tacx NEO 2T (data set here):

image

As you can see, it’s pretty darn close. Oddly a bit wobbly on the very first interval – with the PowerTap P2 unit a bit lower than the other two. After that, it’s perfectly happy there. Who knows, maybe the P2 pedals weren’t quite ready for that wake-up call yet. After that, we’re talking everyone within a few watts in most cases. A bit of disagreement on interval #7 from the Quarq as well.

The above is a perfect example of even 2-3 power meters/units that are widely respected in the industry for being incredibly reliable accuracy-wise can sometimes differ in certain situations. It’s actually interesting in that I’ve seen the Quarq DZero seems to pick up some of the instantaneous spikes a little more than other trainers/power meters I’ve been testing. Specifically at the 1-second level, meaning, the first one second of a power surge.  You can see it below where I’ve shown (with the three little dots) the first second of that surge and the Quarq shoots higher. The question that’s nearly impossible to understand is whether that’s correct or not. That could very well be a case of Quarq is refreshing faster behind the scenes and nailing the initial power inflection better than the others.

image

It’s actually a small pattern I’ve seen in recent weeks on a variety of different trainers and pedal-based power meters that I’ve mixed and matched. It’s also not something I’ve seen in the past when I’ve used the DZero prior to the semi-recent firmware update. Maybe it’s more accurate now, or maybe it’s less accurate now. In any case, that’s a curiosity for another day.

So, let’s move along – this time to a Zwift session. This was in simulation mode (meaning, it’s replicating ascents/descents/etc…). This was the Titans Grove course, which I’ve been using for indoor trainer testing this year because of the demanding terrain – specifically the rapid up and down segments up in the hills part of the course. It also has the flats of the desert for some nice variations in small and big rings. Here’s this data set:

image

As you can see, the three units are always within just a couple watts of each other. Let’s zoom in on a few sections. First is the initial sprint. I treated this as a lazy warm-up sprint since I was only a few minutes into the ride, so more of a 500w power surge than a proper sprint.

image

Looking at the above data, you’ll see that there’s some slightly higher values coming from the Quarq on some of the surges (this is shown with 3-second averaging to make it a bit cleaner to look at, but you can look at the raw data at the link above if you want). Still, the P2 pedals and NEO 2T are incredibly close, and frankly as is the Quarq as well.

As we get into the start of the rolling hills, where the power quickly oscillates up and down, we see all the units tracking very closely:

image

It’s frankly kinda boring to analyze how closely these units track. We do see a bit later on some slightly more visible peaks from the Quarq, but it’s pretty minimal in the grand scheme of things:

image

And then finally that sprint towards the end coming in on near 800w (shown below though with 3-second smoothing to make it easier to see what’s going on):

image

Again, pretty darn good…and pretty darn boring.

So, let’s switch it up one last time – this one over to The Sufferfest for a highly fluctuating ERG workout. Technically, despite how this looks, this was actually an ERG structured workout. It’s that the specifics of this was mirroring a team time-trial, so you were changing target wattages every 20-30 seconds on average. It was nuts…and also a lot of fun. In any case, here’s that data set:

image

Obviously, you can see the PowerTap P2 pedals and my Edge 530 were having a bad day in their intimate relationship. No idea why all the drops. Perhaps I had the Edge 530 in a weird spot or something. No biggie, doesn’t really impact what we’re looking at.

Here’s zooming in on one of the essentially repetitive sections of stepping up in wattage over and over. In most cases it’s within a few watts, but I still see the Quarq a little bit higher here and there than I’d expect.

image

But in general, these are still incredibly close – as we see here again:

image

Oh – wait – what about left/right power balance accuracy? Sure, let’s take a look at the TrainerRoad 30×30’s first since the data is a bit cleaner to unmask. In this case, we’re looking at the left and right power as compared to the PowerTap P2 pedals. And in particular, I’m zooming into 6 of these sets, because there was an ANT+ dropout earlier in the workout to one of the recording units, so that’s distracting (and it could be the unit receiving).

What you see here though is there’s still some random left/right balance spikes where things go crazy for 1-2 seconds on the NEO 2T:

image

Every single one of these instances is connected to the very last second or two of the interval. In the case of this specific workout, while certainly not a cakewalk, it wasn’t horrifically difficult. Meaning, I wasn’t doing something crazy different in the last second or two to my knowledge that would trigger this (obviously, under the covers I must have been).

Zooming in more though, you can see what’s happening. The power values go crazy for the left/right balance specifically (though total power is unaffected). Note in the middle how the PowerTap P2 pedals show I stay roughly balanced.

So what about non-ERG mode, something a bit messier? Sure, no problem. Ask and you shall receive:

Ok, that’s a mess to unravel. So I’ll make it simpler for you: It doesn’t quite seem right.

Specifically, the NEO 2T shows me as significantly more imbalanced than the PowerTap P2 – massively imbalanced. As you can see though, when (briefly) my power is steady-state, it normalizes. But as I shift power, it goes a bit wonky. So I’m gonna say that this specific aspect needs a bit more work. Personally, I’ve never used left/right balance on a trainer for anything before – so this isn’t a huge loss to me (and none of the major trainer apps support it anyway).

Oh, and in case someone wants to know about cadence – zero issues. Absolutely spot-on for me on all my rides:

image

I know some people have had cadence issues on the 2T, specifically around longer derailleur cages and/or different crank arm sizes. That’s because on the NEO 2/2T the cadence sensing is actually picking up your crank arm going past it, versus most (all?) other trainers are doing an estimated cadence. In any case, Tacx says that the recent .32 firmware update should fix this for most people. Still, Tacx says for specific crank arm combinations there may be issues where it’s not detecting the metal passing by. In my case, I’ve run with 175mm crank arms without issue.

Ultimately, for what I’m doing, I’m pretty darn happy with the accuracy of the NEO 2T. I’d have no issues using it for power meter testing going forward, which is sorta my basic benchmark for whether or not I’ll use a trainer in the DCR Cave after a review is done.

(Note: All of the charts in these accuracy portions were created using the DCR Analyzer tool.  It allows you to compare power meters/trainers, heart rate, cadence, speed/pace, GPS tracks and plenty more. You can use it as well for your own gadget comparisons, more details here.)

Trainer Comparisons:

First off – if you’re trying to decide on a trainer, check out my complete recommendations guide that’s only a week or two old.

I’ve added the Tacx NEO 2T into the product comparison database.  This allows you to compare it against other trainers I’ve reviewed.  For this post, I’ve compared it against the Wahoo KICKR 2018, CycleOps Hammer 3 and Elite Drivo II. I could have tossed in the Tacx NEO 2, but frankly there’s no database line item that’s different there. The only difference is the lack of ‘slip’ I talked about earlier, which is so tiny that most people probably wouldn’t notice it compared to a NEO 1/2.

Summary:

DSC_6030

The Tacx NEO 2T continues with the rest of the NEO series in retaining its title as one of the best trainers in the industry. Sure, the road to get here was a bit rougher than years past, but hey, better late than never. And, based on the general fiasco that this year’s indoor trainers have been across all companies – Tacx actually got their house in order faster than others. So there’s that too, I guess.

Still, that won’t matter 3 months or 6 months from now (or even today). It’s all water under the bridge. What matters is how well it works today, and I have zero issues with it from a power/cadence accuracy standpoint or a reliability standpoint. I do still maintain its a bit edgy (bossy perhaps?) in ERG mode, and I’d love to see Tacx introduce some sort of option in their app to make ERG mode a bit less abrasive (more like the previous NEO units, or perhaps the Saris H3). And, of course, I’m hoping that as they look to implement Cycling Dynamics later this year, that they’ll sort out some of the left/right balance items. Though again, I’m not sure how many people will actually leverage that, given the trainer apps don’t support it.

As I said somewhere up earlier in the review – if you’re looking at getting a new trainer and are considering the 2T – there’s no reason not to get it. It’s a great trainer now. If you’re looking at a solid deal on a NEO 2 (non-2T) – that’s also a great trainer, and given the right deal, I’d probably pick that up instead and apply the cash somewhere else in your life. And for those with the NEO 1/2 already, unless the minor virtual tire slip issue really bugs you, I can’t see much of a reason to upgrade to the NEO 2T from those units.

I’ve oft noted that the NEO series is typically the trainer I use when I’m not doing trainer reviews, and I suspect that’ll probably be the case when the dust settles this winter.  It also helps that I can fold it up on itself at home and it generally keeps the kids from messing with the cassette. Sometimes it’s the little things….or little people.

With that – hope this helps, and thanks for reading!

ProductAmazon LinkClever Training Link (Save 10% with DCR10BTF)Note
Basic Trainer MatThis is a super basic trainer mat, which is exactly what you'll see me use. All it does is stop sweat for getting places it shouldn't (it also helps with vibrations too).
Cassette Installation/Removal ToolsThere are *many* variations of cassette removal tools, this is the best bang for your buck. Don't overthink this. You'll likely only use this tool once every 2-3 years.
Front Wheel Riser BlockHere's the thing, some people like front wheel blocks, some don't. I'm one of the ones that do. I like my front wheel to stay put and not aimlessly wiggle around. For $8, this solves that problem. Note some trainers do come with them. Also note, I use a riser block with *every* trainer.
Shimano R7000 105 Cassette (11-speed)This is a Shimano 105 cassette (thus, slightly more budget compared to the Ultegra), in most cases, you probably won't notice the difference. Ensure that the number of speeds matches your bike (e.g. 11-speed, 10-speed, 9-speed, etc...).
Shimano R8000 Ultegra Cassette (11-speed)This is a Ultegra cassette, you can save about $10-$15 by picking up a Shimano 105 instead. Ensure that the number of speeds matches your bike (e.g. 11-speed, 10-speed, 9-speed, etc...).
Tacx Tablet Bike MountI've had this for years, and use it in places where I don't have a big screen or desk, but just an iPad or tablet on my road bike bars.

    First! sorry, had to.

  2. John Reinke

    Thanks, Ray. This is the review I’d been waiting for. I’ve been saving up a while for my first trainer, and this is the one I’d been leaning toward, assuming the firmware updates resolved the problems you’d found initially. Now, I only need to find a good deal on the trainer as well as Zwift!

    • Si

      Hi Ray,
      quick thanks for all your hard work over the years.
      It’s strange that the Neo, which is effectively 5 years old is still having problems.
      I really think that all the companies need Ray to be on the payroll as a product tester.
      New product designed, tested, accurate and problem free, at launch…….
      Happy days and happy customers.

      Or am I being unfair to these companies and their expensive products? Cheers Ray.
      PS I’m very happy with my Neo 2

    • I think in most cases when companies make shifts, we see initial teething issues. In this case, the substantially more powerful internals caused some unexpected downstream issues around control/accuracy.

      Though, they do seem to be sorted.

  3. Martin

    What do the isokinetic and isotonic options do?

  4. SilentLegs

    “1) Ensure you’re using the small ring up front: This is for ERG mode specifically, shift into the small ring to get better control”

    Why is the small ring better for ERG mode? How big is the difference? I’ve always used the big ring in ERG mode on the Flux and now on the Neo 2T since that resembles my outdoor riding.

    On the 2T lately I’ve ended up in relatively low cadence(under 70) on intervals over 400 watts when riding in the big ring and using the 3-4 easiest gears on the cog.

    • The difference is pretty significant in my experience across many trainers, including the NEO. Essentially in a bigger ring it increases the speed of the flywheel, which is roughly akin to trying to control an out of control car versus a slow-moving car.

    • DrPeperino

      So the benefit is in the transient of time required to reach the target, not in the precision with which the target can be met. Is this the correct undertsanding?

      I’m asking becuase actually my recent experience (with a Direto 1st edition and a Sworks power cranks PM) is that when I change from 52 to 36 (I always try to select a cog that will keep the chain as straight as possible, so in general I should go up 2-3 gears towards bigger cogs) I also see the Power Meter of the bike get closer to the Power Meter of the Direto (thou it’s always lower, never on target or higher). So i started doubting that the correct understanding is not about the speed with which the trainer is able to move the resistance to a new target, but about the accuracy with which it is able to hold it.

      thanks
      Luca

    • Blair

      Hi, is the recommendation to use the small ring in ERG mode primarily a “feel” and muscle activation issue or are there power accuracy considerations as well?

    • CowRob

      I think Zwift has gotten better at this recently. I can use the big ring and Zwift seems to not go hugely over the demand. Well, it’s easier to keep it in the range on a workout.

      TrainerRoad still seems to not treat TBR very well. I can get massive distances by riding a workout ‘hot’. Getting incredible speeds, near 30 mph. It’s easy to over power rides.

      I wonder what Zwift adjusted, or is it just me?

      Thanks for the longer time review.

  5. Patrik

    ” I could have tossed in the Tacx NEO 2T, but frankly”
    Should be NEO 2, not 2T.

  6. Neil

    I seem to be having issues when running 2 apps at the same time and using the Neo 2T. TraineRoad on my Andriod connected by ANT+ and also connected to Zwift ATV connected by Bluetooth. (trainer control disabled in Zwift. The traiberRoad app controlled the trainer for the first interval but after that, would not control the trainer. Checked that zwift hadn’t stolen control and i hadn’t.

    Similar thing using Xert on an IPAD – cable ANT+ bridge to IPAD, Zwift as above. Again, xert wouldn’t control the trainer. Xert as above and zwift on a PC connected by ANT works perfectly. TrainerRoad on it’s own works perfectly, so i’m thinking there is some issues between the apps and ATV. Any ideas?

    • DrPeperino

      If that can be of any help: I have a Direto and not the Tacx, but I control it with the Garmin (which is reading the power from the bike power meter), I read it with another garmin, and I have also Zwift on the laptop connected to the bike power meter (all of them via ANT+) and everything works: the main Garmin controls the Direto, reads the bike power meter and returns that value, the secondary Garmin reads the power from the Direto so that I can compare 30s average of bike and trainer instantly, and Zwift reads the bike power meter but doens’t take control over the Direto.
      Same if I tell Zwift to take power from the Direto: it reads but doesn’t take control.

      In this configurations I run only ERG mode.

      ciao
      Luca

  7. Neil Jones

    You commented on Road Feel and in particular referenced Zwift – could you confirm that Zwift is now supporting this for the 2T as it still isn’t allowing it to be enabled for the Neo Bike which has the same underlying internals? I had been hoping this was just an oversight and quick fix with Zwift needing to add the 2T and Neo Bike to their look-up table, but Zwift’s public response (for the bike) so far seems to have been “Meh, perhaps we’ll think about it one day” which doesn’t fill me with confidence.

    Hopefully it will be addressed before long, but I’d feel aggrieved if I bought a 2T on the understanding that Road Feel was working with Zwift only to find it wasn’t, so it might be worth caveating that section *if* Zwift isn’t yet supporting it on the 2T, irrespective of any promises they may have made.

    • Dave Lusty

      Agree, it’s weird that this isn’t working and very frustrating as I loved road feel on the 2.

    • Soulby

      I have a 2T and can confirm that road feel works in Zwift. It actually startled me the first time I went over cobbles! If you go to Zwift’s settings, there’s an option to turn on road feel.
      I connect via BlueTooth, so can’t comment about ANT+.

    • Paul

      That’s the bug, it works over Bluetooth but not ant+. If you connect using ant+ zwift doesn’t recognise the trainer and doesn’t show the option.

    • Dave Lusty

      yup, and since Bluetooth sucks I’d rather stick with Ant+ and miss out on road feel!

  8. Paul

    At the moment the road feel doesn’t work in Zwift using ant+. Tacx say it needs zwift to update their end, the zwift support pages say they are aware.
    Very minor annoyance that will hopefully be fixed soon.

  9. Nick

    Good review as always.

    But.

    I have owed both the Neo 1 and Neo 2 for the past thee years – the virtual slip drove me insane. If you’re a sprinter, racer or ride track, it’s annoying to no end. And with that reason, I sold the Neo 2 and got the latest Kickr with the Climb. I was tempted to stay with the Neo and get the 2T but just couldn’t. I’ve already had two Neos replaced under warranty.

    In all honesty, I much prefer the latest fall 2019 Kickr. It’s somewhat quieter than the Neo’s magnetic hum. The Kickr doesn’t overshoot in erg and is more instantaneous during on and off intervals. I turn off erg smoothing. The Kickr’s flywheel is more akin to road feel than the Neo’s magnetic flywheel. Calibration isn’t bothersome either – I just do it after a session which takes less than than 1 min to do every two weeks or so.

    Each to their own.

    • Gideon Den Hertog

      Thanks, this is really helpfull. I’m looking to buy a trainer, but have put it off due to the lack of information/data about low speed resistance/sprinting. As a sprinter, finding suitable equipment is often quite a bit harder. Have broken my fair share of rear wheels and found bikes to be too flexible.

      @dcrainmaker: this might be an interesting item. How does the low speed resistance of trainers compare? This seems to be something nobody has reviewed yet. Or I at least I haven’t found it.

    • This is a difficult one to quantify. A 50kg rider on a weighted flywheel trainer accelerating from 10km/h – 30km/h in say the 53/16 will be very different to a 90kg rider performing the same test.

      And with the Neo 1/2/2T/Bike and Kickr BIKE having ‘virtual inertia’ flywheel based on rider weight, what feels ‘good’ to me may feel all wrong for one rider may feel awesome for another. It’s also an issue for anyone using a Neo over BLE that hasn’t set their weight in their Tacx Util app (ANT+ will send rider weight to the trainer via most apps…. BLE doesn’t and it needs to be set in the app).

    • Gideon Den Hertog

      Objectively the resistance the trainer can sustain at 10 km/h could be quantified. That would help a rider to compare it to his/her ftp. If it is below his/her ftp, the trainer can’t handle climbs with a gradient that you climb at 10 km/h (with your specific ftp/kg).

      So if you push out 300 watts at ftp, and the trainer can only deliver that resistance above 18km/h….. you can’t realistically climb stuff like Alpe d’Huez when you’re 80kg right? Because you’ll average something like 14km/h. For steeper stuff that’s above 12% this holds even much more. Please correct me if I’m wrong though.

      Anyway if there would be trainer powercurves, or even just one or two lower speed resistance figures, that would help the more powerful (and heavy) riders a lot. Love to hear your views on this.

      ps, I understand that a physical flywheel will help to provide extra resistance momentarily, but to keep it simple, let’s leave that to the side (by that I mean bursts of power and resistance).

  10. Oliver

    Hey Ray, thanks for the review.
    I’m thinking about upgrading my Neo 1 to a 2 T not due to the tire slip or something but due to the fact my new bike got a RAT Axle and the 2 T is the only bike with native thru axle support, right?
    So the best/only option is getting a Neo 2 T or use a different bike on my old Neo 1

  11. Chris Benten

    Are PowerTap Hubs still around? For Speedplay pedal owners? What is the Hub vs Crank system accuracy comparison? Seems like a very small market for them now. Must be cheap as heck to manufacture after all this time.

  12. Steve

    I need to have a look around the house for some Anaglyph 3D glasses as I’m sure some of the power charts might have some interesting 3D patterns in them…

  13. Marcel

    any news on clever training fall vip sale?

  14. Richard G

    Is there an operating temperature range for this trainer? The use of magnets for resistance makes me worry that it’ll be less effective / accurate at sub zero temperatures (which my garage sadly often gets down to in winter).

    • Ihsan

      I had the same concern and checked the manual. The only thing I could find was for neo2, which is -20 to 50 degrees Celsius. Would work in my mid Atlantic garage.

    • Tobias

      I used the Neo 1 outside in well below zero temperatures (Toronto, ON) for up to three hours and never really had a problem. Obviously it was stored inside and only running when in use.

    • Ihsan

      Thanks @Tobias!

      I’ll be keeping it in my non conditioned garage, so a real case helps a lot!

    • Frank Jansen

      Just make sure the space is dry. Electronics don’t like humidity.

    • Ihsan

      Well “dry” is ache achievable, humidity is a whole lot of separate problem here in mid Atlantic US. It will be humid, body crushingly humid at times.

  15. Gabi

    Ray, I see there isn’t a link for the Neo 2T for Clever Training Europe and searching through their website I can’t find it either. Do you know something about it?

  16. H. Veldman

    “based on the general fiasco that this year’s indoor trainers have been across all companies ”
    Sorry to belabor a point, but I’m not sure what this means.

    • GeeDub

      In a nutshell, pretty much every trainer reviewed in 2019 was a dud. All needed a firmware fix or three to get them to acceptable levels…

    • _tido_

      Yes, but it was the same in 2018 with the core, the neo 2, and in 2017 with others. I know that people are more complaining than providing positive feedback on blogs or forum, but all those issues reported by customers are making me reluctant to buy one.
      Even if vendors claim to having fix those, What if I fall on an old series ? Given the weight of the beast it’s really not easy to send it back.

    • Dig deep enough with any product and you’ll find someone having a shit of a time. Mostly it has been us with trainers and things in 2019. This year was a highlight of lowlights, for whatever reason. Add to the list the R1, BKool Air, and a few others I won’t even bother reviewing until I get promised ‘revised firmware’.

      If you have concerns about shipping/returns then purchase locally or have the store/site/etc confirm their policy on returns so you won’t be out of pocket.

  17. Kamil

    Hi Ray, I have got a small idea for you to include in future trainers’ reviews (and also adding to charts for current ones). Correct me if I am wrong, but currently only Wahoo’s trainers have got native PowerMatch/Link – the feature similar to one in TrainerRoad. The only difference is that TR is a middleware for trainer to get data from crank/pedals, whereas Wahoo devices create direct connection with given ANT+ power meter – that means that in case of ERG, they are independent from other app. I think it is a cool feature which should be implemented by other brands – because there is no reason not to do it. Also from developer point of view it is easy 🙂 It’s a great feature when you want to work on the same power values both indoor and outdoor.

    • Elite also have PowerMatch which does the same. IMO PowerMatch/Link/etc is a workaround for what should never be needed in the first place if the trainer was accurate across all ranges. If trainers had a claimed accuracy of +/-10% and you wanted more accurate power, sure… or if trainers were a few $100 cheaper and didn’t do power at all, sure. When companies sell trainers with reported power accuracy ranges between 1%-3% then they need to deliver trainers that are within 1%-3%.

      Further on this, PowerMatch/link/etc can add delay into the loopback of ERG which has adverse effects. Most trainers perform better using their own internally calculated power.

  18. David Dominguez

    Upgraded my 2 to the 2T for Focus’s RAT axle compatibility. Works great. Now I’m more likely to take it off to go riding outside since it’s not as much of a hassle to swap in and out.

  19. Don Rhummy

    Ray,

    I’ve noticed that Tacx seems to be out of ideas for improving their Neo trainer. If you had carte blanche, what would you do to make the next version an amazing upgrade?

    • I’d probably incorporate a CLIMB like function.

      I’m not sure what else beyond that to be honest. It’s sorta one of the best trainers out there and I think most of the focus for indoor training is going towards accessories around the platform.

  20. Paul S.

    It’d be interesting if Garmin could leverage their ownership of Tacx and the “road feel” component of the trainers, and the fact that modern Edges have accelerometers, to create a way to record the “road feel” of a ride for future playback on a trainer. I’d much rather do that than use something like Zwift.

    • The Duffman

      That My Friend would be awesome, i would love to be able to ride a race route, and then bring it back home and be able to train on the same feel. Just to get an idea of how it feels when i am forced to stay indoors.

  21. The Duffman

    Ok i know this is always asked and the answer is always it depends, and this comment should be on the review post….but i have been reading your reviews and looking and my mind is now numb. (love the site too come here for everything, and try to get anything i can with the DCRM VIP to help support the site)

    I have an Old Magnus and want to graduate to the direct drive trainer, it seems like there are really no major losers in the Kickr Core/Kickr/Neo(2/2t)/(finally) Hammer.

    Seems the Kickr Core is the logical choice, but if i want some of the fun extras and additional incline go with the Neo line. I am not sure the Hammer can beat the Core, or the $200 price difference can have the Kickr beat a Neo with some of the little extra things it offers……….I would love opinions.

    • We talk on the incline a bit in this week’s episode of the FIT File Podcast that’s not quite published yet. But ultimately, we both agree that nobody really wants to ride a trainer at 25% incline. Or for that matter, indoors either.

      I think the most anyone really wants to actually do is perhaps 12-13% (and very few routes go above that), and, if you use Zwift and don’t change the defaults, it’ll half it anyway. Food for thought…

    • Duffey Ainworth

      Thank you for the reply, and you are totally right about the incline. I live in Middle TN and we have some nasty little kickers around the Nashville area and still none are over 14% so to even think about needing that extra inside is really beyond my needs.

      So by that logic the Tacx is really looking at some “high level” features. Think i will be keeping my eye on the Kickr Core and looking to the VIP 20%!

      Thanks again.

    • Moritz Haager

      So I rode Zoncolan on the Tacx app today on my Neo2T. On the grades above about 14% I found I was getting slip. This was in the 270 to 300 watt range at about 45 rpm and I weigh 73 kg. Interestingly I found this to occur when I was sitting and not when I was standing. Seemed like I could keep the pedal stroke smoother standing. I was a bit disappointed that this was happening though. Is that inline with what you found was well?

    Hi Ray,
    Great review as usual and I have been waiting for the full review as I am in the market for a new trainer since my last one failed badly.

    One frustration though is that speaking to the local distributor they won’t arrive in Australia till February 2020. This is disappointing – I guess they know that Australia has great weather and figure that those in the northern hemisphere are going into winter – and therefore need it more/will sell more. I guess all I am saying is that if I want to buy locally for the local store support, I’ll have to be patient.

  23. Vicente Piorno

    Many thanks for your review, Ray

    Regarding this:
    “Still, Tacx says for specific crank arm combinations there may be issues where it’s not detecting the metal passing by.”

    Is it possible to know which are these specific crank arm combinations?

    • I’ll see if I can get a list. It sounded like there were multiple factors that could trigger it. Meaning, it wasn’t just a specific crank arm length but also considerations like the materials, etc… (since it’s detecting the metals of the pedal spindle passing by).

    • JD

      Simple workaround = tape a small magnet on crank arm?

    • Vicente Piorno

      Thanks, Ray, that would be great. I am considering the NEO 2T as my next trainer, and would like to know if it’s fully compatible with my trainer bike.

    • Mark PUT

      I think it is also (or mainly) the lenght of the chainstay. Because if you move you’re hand in front of the sensor, it detects it. I ride a mtb, and when I elongated the crank, cadance became normal.

    • Yeah, one person attached a small tea spoon (like, a coffee spoon) to their crank arm and that fixed it.

    • Dave Lusty

      Adding metal bits to the cranks is NOT a fix for this issue, which is a combination of firmware and hardware issues. If you’re having these issues, log it and Tacx will swap out the trainer for a working one. For a start it’s not a magnetic sensor, and will happily detect a foot several inches from the trainer (my feet contain no metal AFAIK). I posted a video of this on Facebook recently at link to facebook.com (need to be a member of the group to view).
      The whole crank too short thing is just a way to avoid the real subject, which is a bunch of trainers which were broken by newer firmware.

    • JD

      So the cadence sensor is on the non-drive side?
      Is it optical or proximity/infrared based?

    • Dave Lusty

      yes it’s non drive side only. I’m not sure what kind of sensor it is but I’d guess it’s setting up an EM field and measuring the fluctuations in that. Certainly is sensitive and not related to the cranks when it’s working properly. Once you see one working correctly it’s obvious that others are duff units. All the talk about spoons and metal sticks does is allow you to continue using a broken trainer and avoid talking to support.

    • Ross F

      I tried that and it didn’t work for me.

      The teaspoon trick nails it though.

    • Ross F

      My last comment was in regards to the small magnet. It doesn’t work.

      Dave Lusty,
      Thanks for posting that video link. Very interesting.
      Did you review the cadence data in the Connect app (or other) to see if the cadence was being recorded properly?
      When I tried the same test the Garmin readout does much the same, but the graph produced shows big gaps being filled in by the software.
      If I use my teaspoon trick the cadence sensor response time is razor sharp and looks similar to the Garmin or Stages PM cadence sensors.
      When I contacted Garmin they had me wave my hand past the sensor to verify it was functioning correctly. It definitely doesn’t require metal for this sort of sensor.

      Funnily enough, my cadence sensor prefers me barefoot. Possibly something to do with all the steel left in there? There’s more than a teaspoon at least.

      Anyway, I’d love to get to the bottom of the cadence issue if it’s based on a hardware or firmware fault. It would be nice to have the cadence working correctly without any adapters when Cycling Dynamics comes online. If only to look at odd looking peanuts and wonder what the hell it all means!

    • Mark PUT

      I am convinced it is due to a longer chain stay and higher ground clearance, as found in mountain bikes compared to road bikes.
      Whether the software or hardware should be able to handle it, is to be tested. Does anyone with a mtb (chainstay 448mm, 29inch wheels) have no trouble recording cadence, and does anyone with a road bike have cadence issues?

    • Ross F

      Don’t forget about Q factor as well. It all adds up.
      I’m inclined to say forcing the sensor into the existing casing is the problem? I’d like to know the answer.

      In the interest of due diligence, I’ll lodge another ticket with Garmin/Tacx and report back.

      R.

  24. Thanks, Ray, it seems you say it does not support FTMS at the top and in the grid you say it does. Alex

    • Good catch, I had consolidated some database fields down to simplify stuff. Just clarified that while it’s not FTMS, it does support most apps that way. Same is true of KICKR.

  25. Damien

    5000 miles and counting on my Neo 1. Couldn’t be happier. Great trainer and never had an issue.

  26. Francis C

    I’m looking for a good high end trainer to take with me to my races. I tend to travel with the family and wifey won’t let me out anymore so I figured I’d train while they’re sleeping. Will this fit the bill? Thanks😁

  27. MattB

    In terms of external appearance differences, rather than just a thin blue stripe, the most obvious thing compared to the previous two iterations is the bolts are now black not silver!

    • Oh wow – I never even caught that. Nicely done!

    • It’s funny… I noticed the bolts right away in your photo, but I couldn’t see the racing stripe for some reason. You described it as the “back panel” of the leg, so I focused on the rear of the leg and could only see the same blue stripe that’s on the 2. I finally noticed the racing stripe later in the article, so I scrolled up to the comparison photo again and could suddenly see it clear as day! Brains are funny that way. Sorry to nit pick, but why do you consider that the back panel? Seems extremely front panel to me. 🙂

    • Yeah, I guess it’s just more the back leg – which was the panel for the back leg. Moreso than I suppose the back panel.

  28. Carlos

    One year ago I bought a Neo 2.

    I don’t get the rider weight reason not to support FTMS. I set my weight in the Tacx utility app. I set my weight in the Xert app. Why do they need to share it via the communication protocol?

    From a mechanical point of view I am happy with the trainer. But for a €1300 price tag it is really annoying not to have FTMS available. Also there were some problems with cadence and to work around those I needed to downgrade from firmware 0.18 to 0.15. I don’t think they did any work on the firmware until they released the 2T.

    After I added a power meter to my bike I stopped waiting for a solution on the cadence issues so I do not know if they are fixed.

    Again happy with the hardware but not happy with the overall experience. Now they say the will implement cycling dynamics. I guess that make it even less likely that the will ever put FTMS on it.

    • Yeah, I don’t fully understand either. I believe the thinking though is that the app (such as Zwift) can set the value, so that it’s a bit cleaner.

      FTMS & ANT+ FE-C don’t support Cycling Dynamics anyway, so that part doesn’t matter much there.

  29. frank1e

    heads up in the UK at least – Wiggle have 25% off the Neo 2 which in my book would = “solid deal” territory….

  30. John

    I picked up a 2T and right before my starting my second ride I noticed a cricket sound coming from the trainer. I unplugged it and the sound went away. I plugged it back in and just let it sit. After a few minutes, the sound was back.

    Is this normal?

    • imar

      I just got a 2T and hear the cricket sound as well. It also seems like the 2T is louder (Fan noise) than the Neo 1. Not happy about that. Contacted Tacx support. Let’s see what they say.

  31. Lada

    Hi Ray, I have to thank you for your hard work. Helping me a lot. I am just curious you are using 0.33 fw version, I have only 0.32. Do you know what is the difference? Second question is about documentation e.g. for newcomers – have to say this is big pain – only forums and people like you. Any idea where to find more info how to build up Neo2t ecosystem – not only hw but especially apps

  32. Jone

    Heres the link to Garmin forum
    link to forums.garmin.com

  33. Blair

    Thanks for the heads-up on the Neo 2 sale. Just ordered—should arrive on Tuesday. Looking forward! FWIW, I’m still on the 2014 Kickr, which has worked great for over 13,000 miles now. In the testing I’ve done, though, it’s always tended to read a little high (10-20 watts). Disabling the strain gauge a couple of years ago narrowed the gap a little. I’m excited to see how the Neo 2 stacks up against the P1’s and the Assiomas.

  34. Andrew

    Hey Ray just FYI getting cycling dynamics from Tacx Neo2 for the last week or so if recorded on a Garmin device – FR945 in this example.

    • Those are technically not yet Cycling Dynamics – but rather power balance. The Cycling Dynamics metrics will add in things like where the power output is within each stroke.

      Soon they say…soon!

      Cheers!

    • Robert Ravona

      We’re almost a year now since cycling dynamics was supposed to come out. Tacx remain silent. Pretty disappointing…
      Any chance of “Poking the Tacx bear” Ray ?

  35. North Krimsly

    How much does the Neo 2T rock side-to-side, and does it add to comfort? I ask this because I have a Kinetic Rock and Roll Smart Control wheel-on trainer and I’m thinking about upgrading to the 2T. I really like the side-to-side rocking motion on the Kinetic; I think it makes a big difference in comfort compared to for example Spinning class bikes. But I only use a few degrees of the available rocking motion on the Kinetic. Just a little bit goes a long ways in comfort, in my experience. Thoughts?

    • Greg

      The Neo rocks very subtly to the point that it doesn’t provide nearly the saddle relief the Rock and Roll trainers do. I have a hard time doing anything over an hour with Static trainers and the Neo, with the slight movement doesn’t buy much for me. For reference, I had the older Rock and Roll Kurt Kinetic trainer and I could do 3 hour rides on it.

      I’ve been using the Kickr 2018 on a rocker board which gets me that needed side to side motion. This is pretty awesome product:

      link to gravi-trainer.com

      I’ve added a turntable under my Wahoo climb to allow a slight movement to my handlebars. Very essential in my opinion to get the outdoor feel.

      I previously owned the first generation Neo comparing it to the Kickr over a couple weeks. I finally decided to sell the Neo because I felt the Kickr had a more realistic “riding outdoor” feel. I also could see differences in the data using my P1 Powertap pedals. My outdoor torque efficiency is usually 70 to 75% at cadences from 90 to 100. On the Kickr my torque efficiency was very close to those numbers at those cadences. On the Tacx Neo my torque efficiency was 85% with the same cadence which I’ve never seen outdoors. There’s a spot at the top of the pedal stroke outdoors where the resistance just seems to go down. The resistance then goes up as you push the pedal down. The Kickr seemed better simulating this feel whereas the Neo seemed to have a constant resistance throughout the entire revolution.

      That was over a year ago. I was curious to see if the 2T version improved anything so I purchased one last week and did my first comparison last night doing 20 minutes on the 2T and then 20 minutes on the Kickr. I think the 2T has really nailed it. Don’t know if it’s a firmware upgrade, or the improved motor on the 2T or if my first Neo was bad but I think the 2T matches the outdoor quality feel just a little more than even the Kickr. I’m going to do another test tonight.

      Why does it matter to me? I want to stress my legs the same way I do indoors as I do outdoors. So often I train inside for weeks during the winter just to go outside to get my legs hammered. Even on flats, the outdoors work my muscles differently than indoor training.

    • North Krimsly

      Greg, thanks very much for the detailed reply. Do you use your gravi-trainer with the Neo 2T as well, or just the Kickr? I was hoping to avoid buying a rocker board but that might be what I need if I want the comfort that my Kinetic offers. I’m tempted to go with the Kickr 2018 or Kickr Core plus a rocker board and see how that is for me.

    • Greg Smith

      I’ve used the Gravi-trainer with both the kickr and Neo 2T. It works with both and feels great. I have the long board version so the climb rocks along with the kickr. This is a picture before I added a turntable under the climb I got from Amazon. This setup is pretty awesome.

      I specifically purchased my first Neo for the slight rocking motion but I found it wasn’t enough for me. The rocking I get on the Gravi-Trainer just sitting pedalling is more like riding outdoors. Swaying probably only 0.5″ an inch side to side but just enough movement to make faster cadences feel more natural. My outdoor cadences are between 90-100. On a static trainer I always drop that to about 80. Anything above that feels fast. With the Gravi-Trainer my average cadence has gone up to the high eighties. The turntable just allows the handlebars to move millimeters but it gives that outdoor feeling.

      I wish I could use the climb with the Tacx 2T. I love how the climb hits the muscles differently. I can be doing a hard effort just to the breaking point and by raising the incline to 10% suddenly feel relief. I use my hamstrings more on inclines and almost all quads when decending.

      I will keep both for several weeks to decide which one to keep. Let the honeymoon phase wear off with the 2T.

      Another thing I’ve tested is the power of the 2T at low speeds. I’m a bigger cyclist and when I’m on an incline all my friends will leave me in the dust all while I’m doing 300 watts going only 5mph. Both the old Neo and Kickr just can’t replicate the climbs I do at my weight. The Neo 2T seems to be able to (hope I don’t burn it up). I did a simulated climb last night with the 2T using my 34T chainring/36T cassette combo going 5 mph at an average of 300 watts. The 2T felt very close to the outdoor experience and I was suffering the low cadence I endure outside. My Kickr doing the same climb would just increase the speed a couple miles an hour and I wouldn’t get the same low cadence burn. This isn’t much of a feature for small guys but anyone over 200lbs will appreciate it while doing simulated rides.

    • Greg Smith

      Just realized this photo does have the turntable added.

    • North Krimsly

      Hi Greg, this was really helpful. Thanks a lot. I weigh 65 kg with an FTP of 210 watts, so pretty much every smart trainer has more than enough resistance 🙂 The 0.5″ of side-to-side sway with your setup sounds just about perfect for me.

  36. Nicolas Prud'homme

    Hi! I just bought Neo 2 and 2T back to back. The Neo 2 had a really slick feeling, but the slipping issue at grade higher than 11-12% was annoying. Just came off a first ride on the 2T (short), no slip felt at up to 16 % in NYC (which is great).

    Unfortunately, at the start of the ride, and throughout at lower speed (kind of around 1-2 % of grade, almost has the motor to help go downhill stops), there is a huge vibration, like if I was on cobblestone… Have you encountered this problem at the beginning (kind of a break-in issue). It is very annoying, and never happened with the Neo 2…. I feel like I might end up with a Kickr after all.

    Thanks

    • Any chance that’s road feel being triggered?

    • Nicolas Prud'homme

      I have played with the Tacx app during my ride, and it didn’t change. Once I am cruising at higher speeds, it doesn’t do it. I have ridden as a stand alone unit not connected to any software or plugged in the wall, same issue… I have even changed to another cassette to make sure it wasn’t an issue with my cassette…

      Anyway, thank you as usual for your amazing work! If you hear anything about this issue in the near future, please let me know. In the meanwhile, I will go and try the Kickr + climb at my friend’s place to convince myself of buying it.

    • Damon Cahill

      Ray,

      I’m experiencing the same issue, I believe. My situation is I was a previous Neo2 owner. My wife wants to be able to ride at the same time, and we got sick of swapping our dedicated trainer bikes. So, I bought the new 2T via your REI link (great deal!) and she gets the 2 :). Caveat: I’ve only done 2 rides. However, I get that same vibration when increasing power. Once riding at sustained power or decreasing power, it’s silky smooth and feels great. I have of course, checked to see if Road feel was somehow kicking in, even turned off the feature. Still happens with Road Feel off. It’s pretty easy to replicate. My wife also says she can really hear the difference when riding next to me, and even when she happens to be downstairs when I’m riding upstairs. I’m wondering if it’s normal with the new magnets. It’s a minor annoyance, but one I don’t think I should have with a trainer of this price. Some individuals on the Tacx NEO Facebook group are reporting the same.

      So, I wonder if it’s normal? Perhaps it will get better with time with the magnets breaking in? I could, of course, exchange it at REI, but don’t want to go through that hassle if I get the trainer back and have the same issue.

      Any thoughts?

    • Hmm, that’s odd. I can check on Monday and see if I can replicate here. And either way, I’ll poke the Tacx folks to perhaps reach out here. Probably worth putting in a quick ticket online with Garmin support as well, at least to have a record of it.

    • Damon Cahill

      Thanks Ray! I opened a ticket yesterday. I’m interested in seeing what reply you get, and if you experience it at all. I’ll share my reply here, too. Thanks!

    • David

      This might not be connected in any way, but riding the Zwift Richmond course (lots of cobblestones) I noticed that my Neo 2T did as expected and vibrated a lot on the cobblestones, but as I pushed hard on the sprints it smoothed out, which I liked.

      Did you ever get an answer from Garmin/TACX?

  37. Just a quick heads up for folks considering the Tacx NEO 2T:

    REI has actually included the NEO 2T in the 20% off sale: link to bit.ly

    If years of REI trainer sale history is any indication:

    A) They’ll continue to honor it
    B) But they probably have a very small quantity of inventory

    Said differently: Grab it quick! Oh, and the link above supports the site!

  38. macnuts

    DC Rainmaker, thank you for yet another great review.

    Are there different variants of NEO 2T?
    I can see three price tags in your review and there is a “Select option” button on the tacx web page (the button does nothing in any of my web browsers).

    BTW, there is “This device has not been authorized as required by the rules of the Federal Communications Commission. This device is not, and may not be, offered for sale or lease, or sold or leased, until authorization is obtained.” info on that page.

    • I’m only aware of the the single 2T. There’s the previous NEO 1, NEO 2, and now the NEO 2T.

      As for the FCC warning, I suspect that’s old now. Garmin doesn’t permit any products that don’t have clearance from being sold (well, the law doesn’t permit it either).

    • Roberto

      DC Rainmaker thanks very much for your review.

      So far I have seen 2 models of Tacx Neo 2 Smart, being the T2850 and T2875. What are the difference between them? There are several offers for the Neo 2 Smart T2850 with prices around 1000 euros but the T2875 is always at 1300 euros.

      On Tacx webpage the “Select Options” button still does not do anything as far I can see.

      On websites offering both models I cannot see any difference on the specs. (one actually says it ships with a quick release adapter but that is probably not the difference between them):
      Neo 2 Smart T2875: link to bike24.de
      Neo 2 Smart T2850: link to bike24.com

      Do you know anything about those models?

      Thanks

    • Patrik

      T2875=Neo 2T
      T2850=Neo 2
      See start of this page for differences.

    • macnuts

      Thank you for info. Yet, I will wait for NEO 2T with CLIMB functionality 🙂

  39. Fredo

    Hello,
    I read all of your home trainer tests with a lot of fun and attention. But I think that some conclusions about the erg mode might not be right and particularly about the response time of the trainers. The differences found might not be material but software or communication-related with could change one day one the other. The use of Trainer road via a server could explain the latencies observed. If I can afford some advice, it would be better to use local software like Perfpro to test the response time (and the erg mode) of different home trainers and you’ll be surprised how fast they respond.
    I use a vortex tacx (low range HT) with Perfpro controlled by pedals Favero Assioma with a response time of 2 seconds and a good accuracy (Maybe it’s the best deal). This software is very consistent and can be a reference to compare trainer. When I use Tacx software everything is bad but it is an other subject.
    In your configuration, you can not distinguish if the response time is software or hardware and it is the same about the power stabilization.
    Of course, I can understand the importance of testing with software that users will use but it leads to an impossibility to conclude on the hardware part. It is necessary to separate the two to be objective. On the subject of online software, I think they are evolving and improving over time and so yesterday’s test is not the test of today. All of these things make me think that there should be a more repeatable test procedure where the tester has control.
    Another very important parameter is the stability of the cadence, if it is not stable enough it is found on the power curve. I noticed that it depends a lot on the day physical condition of the tester.
    Hoping to have helped, congratulations for your work already very good quality.
    Regards

    • “The use of Trainer road via a server could explain the latencies observed”

      It’s all local. TrainerRoad is local – just like every other app in the market. There are no ‘online apps’ today in the smart trainer world. Everything flows via ANT+ FE-C & Bluetooth Smart FTMS locally. There’s technically no other way to achieve that today, even in some tests companies have done with online platforms it has a local component handling that BT/ANT communications. It’s why I test both FTMS and FE-C in most reviews, and across multiple apps.

      As for cadence, unlike your Vortex which uses estimated cadence, the NEO 2/2T actually uses measured cadence by looking for objects passing by it (as discussed above, some of the pros/cons there). There’s no tie-in to accelerations like in a estimated cadence trainer.

      Finally, as for the ERG mode responsiveness – Tacx themselves admits it’s not perfect – and admitted it was an isuse back in August when I first started testing. You’ll see that in the release notes of the firmware – which I also discussed above.

      Cheers!

  40. Kris

    I currently have the original Wahoo Snap and was looking to upgrade to either the Neo 2t or the 2018 Kickr. I have been using the Wahoo Elemnt to control the snap. Would this work the same or similar if I went with the Neo 2t over the Kickr?

  41. Jouni Holsius

    Doing a little test against power2max power meter.
    Not so good.
    link to forums.garmin.com

    • Ross F

      Hey Jouni.
      How did you get those numbers?
      Are they averages over the whole interval recorded on two separate devices?

    • Ross F

      Hi Jouni.
      I looked at your Garmin connect and Strava lap averages. They are both nearly identical.
      Which is the Power2Max recording? Or are they both a recording of the NEO 2t?
      If both the Neo, you’ll need a seperate device to record what the P2M is reading during the workout. That way you can compare them both.

      I came up with:
      Lap 2= 314/315. (Strava/Connect).
      Lap 4= 261/262.
      Lap 6= 209/209.
      Lap 8= 155/155.
      Lap 10= 367/367.

      If the problem is that the 1030 didn’t keep the NEO on target, that’s one for Ray to test out. My hour of sweet spot is up and I have to get some work done.
      R.

    • Jouni Holsius

      Problem is that edge tells neo to go 200w and neo does not do that (it does 209 ans so on).
      Connect files and strava files are both by power2max readings.

    • Jouni Holsius

      Tested yesterday that edge tells neo to go 400w and neo gives 422w readings in power2max.

    • Ross F

      Hi Jouni.
      Two identical files is not very good for a comparison. You might have a problem with the connection between the 1030 and the Neo during the intervals.
      If you record the activity on two devices at the same time I can have a look at them for you. One device recording the Neo and one recording the P2M.
      I use a laptop for TR workouts that controls the Neo and a 520+ connected to the Stages PM for example. You can then compare the power reported by each unit.
      See link: link to dcrainmaker.com

      Back to your files. The speed graph on Garmin connect shows drop outs ( I think). When things drop out the software tends to fill in the gaps with the best guess it can come up with. That could be what is happening?

      In my last house I had trouble with using a 2.4 BT connection for Netflix while doing workouts. Changing to 5 for internet worked most days.

      HTH. It sucks when a new toy doesn’t work as expected.

    • Jouni Holsius

      Power2max has no dropouts. My max intervall power is about 400w and in neo I can not do that.
      When I start my training program (interval) I can not do that because neo gives 422w out.
      Test it on your own power meter and see results.

    • Ross F

      What did your Neo record as an average for the same interval? Not what the garmin 1030 told it to do, but the average power that the Neo had for the interval.
      If the Neo reports an average power of 400w vs 422w on the P2M I get it. At 400w a very worn drivetrain and BB could come close. It would have to be pretty bad IME.
      You might just have a faulty unit. If you don’t check the average power recorded on both units you’ll never know.

    • Jouni Holsius

      When I controll trainer in tacx android app it gives readings 400w and power2max by edge 1030 gives 422w. I have recorded same training by and. app. and edge 1030/power2max.

    • Ross F

      400w is the target power. You tend to fluctuate with actual power. Even when you are watching a live feed on the phone there’s a smoothing with the readout.
      When I read Ray’s post above, he mentions that the new Neo does tend to overshoot with the FW.32. It’s very short lived apparently.

      Was the average wattage on the Neo the same for the P2M when recorded separately for the same workout intervals?

    • Jouni Holsius

      Tested now with edge1000 and edge1050. Edge 1000 read power to neo and 1050 read p2m.
      Same result. edge1000 gives 400w and edge1050 gives 422w. Recorded same interval.
      I have both edges.

    • Jouni Holsius

      I mean edge 1030;-)

      Hi Jouni.
      The two files posted on the Garmin page are recorded on different days. There isn’t much that can be done with them for testing.
      Can you post two files from the same test as FIT files so I can review them properly? The Strava links don’t let me do much.
      There’s a 1050 now?! Time for a hands on review! 😉

      You’re going to need to test against a third power source in the long term as well. I feel your pain in that regard.

    • Jouni Holsius

      Sometimes strava does not allow you upload same activities twice. You must change time stamps to do that . Dont you know that. You can do that in fit file tool. The files are in sama session.

    • Jouni Holsius

      I can personally send you original fit files by e-mail, if you are then happy;-)
      There are connect files to watch now in garmin site.

    • Ross F

      Hi Jouni.
      Thanks for posting those FIT files on the Garmin link. I ran them through the awesome DCR Analyser tool.
      Strava is a bit of a lost cause for me ATM. I only use it for live segments on my MTB’s Garmin head unit.
      There wasn’t much I could get from the Strava link. Maybe I just don’t know how to use it properly.

      Your Neo and P2M seem to drift apart a little as the power goes up.
      1min @ 150 watts. Neo 2T=149.53W. P2M=154.19w.
      1min @ 350 Watts. Neo 2T=349.15w. P2M=368.44w.
      The files were out of sync by two seconds. I also noticed that you vary your cadence a fair bit in the higher intervals. Heck knows if that’s got something to do with it.
      One thing I have done in the past is to freshly clean and lube the drive train prior to testing things. It’s also worth checking for wear/stretch as that can make a big difference and give results like you’re seeing.

      +/- 2% on the NGeco. +/- 1% on the Premium model and the same for the Neo. You’re right at the edge of things.
      If only you could put out 1000+ watts for a 1 min interval. I think we’d start to see some pretty crazy results for most power meters.

      I was very interested in the P2M file as I’ve been looking at one for my XC bike. All of the reports I’ve heard are that they make a great unit. I’d say it looks pretty solid even though something is off in your situation.

    • Jouni Holsius

      My direto gives solid readings in that chain and chainrings. Chain is good and clean and lubed.

    • Ross F

      If you’ve eliminated all the other variables, there’s something off. Best to take it back.
      Best of luck sorting it out.

    First trainer. So far, so good. Does the Neo 2T support Elite real life videos (films)?

  43. Michael

    Hi Ray. I have two questions about the Neo 2T. #1 I saw you sprinting on the Neo in one of your videos. It looked like the Neo came off the ground briefly during the hard effort. Is that an issue you experience a lot? Note, i’m not talking about the side-to-side “give” the Neo has. Like bar stools (I’ve heard), the 4-legged stools are more susceptible to rocking than the 3-legged ones. Do you think the 3-legged Kickr would be less prone to having that problem? #2 I saw a GPLlama video where he demonstrated how the Neo hinges started to creak. Is that still an issue? Thank you for all the helpful information you’ve provided over the years.

  44. Ihsan

    Guys,

    What’s the recommended pairing procedure if one also has a power meter? I don’t want to lose power and cadence from the power meter, I just want to have the speed from Neo and the controllable features of the trainer.

    Thanks

    • Ihsan

      Well, I got my first ride in this evening, I had Favero pedals paired to edge, and the Neo paired to F3HR as a power meter. The power figures are within 3-4% of each other (Neo reporting the lower of the numbers) but the pedal balance is quite off. My Assiomas started reading about as much as 10% lopsided to the right at the end of August, and Favero guys said it is reading correctly, but now the Neo reports 51/49 after the first ride.

      I’m not sure which is correct, so I’ll keep an eye on it and contact Favero support once again after a week or two.

  45. Jordi

    On Friday afternoon I bought the new Tacx Neo 2T rollers.After my first tests, the summary is that fatal!!!!!! mad::mad::mad:On Saturday I did my first workout with the roller and Zwift. At 10km I began to make noise, like a bowl, as if something had been released internally. Today I took it to the store and they exchanged it for a new one.This afternoon I mounted it, connected it and rolled it. Then to roll little, to the 3km I go the resistance of the roller and begins to blink the light of ignition (the red one) to me, after leaving in rest a while I return to intertarlo and returns to have resistance. This happens to me three more times in a row, with and without tension. I also smell burned and in the Tacx Utility app I see the thermometer symbol in red. In other words, it warms up because it doesn’t refrigerate well. I understand the fans aren’t working? I don’t know, so bad luck I can have 2 new rollers to release, have day problems?!!!!I trusted the brand 100% and unfortunately it will make me change and go to Wahoo. What a pity!

  46. Ray, what are your feelings about the resistance changes while driving in SIM mode on Zwift? In my opinion, virtual flywheel does not replicate inertia correctly when riding flats, as if it did not take into account any “air and rolling resistance”. When I press harder on the pedals, the resistance and flywheel inertia increases very quickly, but after 3-4 seconds the flywheel inertia takes most of the part of cycling power and I am loosing resisnance of the Neo, reportet power goes down to. It looks like 500-200-500-200 with 2 or 3 seconds frequency (link to da data set link to analyze.dcrainmaker.com).
    When I’m riding Elite Nero rollers with powermeters on bikes, I don’t have any problems with power fluctuations, but Nero has got ~8kg of flywheel (including wheels and tyres).

  47. Feri

    So some good news for those who have been hasitating, because of the early flaws of the neo 2T.
    Received it a day ago.
    – Update to 0.32 was easy and flawless via iphone
    – Accurate compared to P2M Ng Eco. P2M has been stable and reliable for years.
    – Cadence works perefeclty (size S scott cr1 pro, 170 mm crank arm)
    – Does not heat over, fan works sliently for about 2-3 minutes after a 60 minutes long workout.
    – In ERG mode change in intervals does not come at you like a train, you have about 2-3 seconds to adapt.
    – No death spiral if you know your limits and how to use ERG
    – No virtual slip
    – In ERG mode + small chain ring and mid in the back, it is virtually silent @ 200W-s, which is 3.2W/kg for me
    – Cons: I might need the extractor tool a tiny bit of rattling surfaced for 2-3 seconds during the 2nd workout. But that’s all 🙂

  48. Moritz Haager

    So my wife just got me a Neo 2T for early Christmas yesterday to replace my gen1 Kickr which has never been accurate enough to use without power meter control. Did my first ride on it on Rouvy going up Alpe d’Huez. Had my Vector 3 pedals for comparison. Used Bluetooth for trainer contriol and Ant for headunit to Vector connection. My average watts for the 1 hour was 282 as measured by the Neo vs 273 as measured by my vectors. Close but not quite as close as I was expecting. For one shouldn’t the Vectors theoretically be higher due to drive train losses? Calculating the confidence intervals I would expect the true value for the Vectors to be somewhere between 267.5 to 278.5 watts (+/-2%) and 279 to 285 watts (+/-1%) for the Neo. So these intervals just miss each other at the high end for the vectors and the low end for the Neo. Obviously hard to know which one is more “correct”. Wondering if people have found their accuracy improved after a few rides, any tricks for figuring out whether the its the trainer vs the pedals that’s more off. Also wondering if anyone has found different results with different software controlling the Neo (I.e Rouvy vs Zwift vs Sufferfest etc) or using Bluetooth vs ANT+ to control it? It’s such an expensive unit — my expectations are it pretty muych has to be perfect or I’m taking it back. Thanks

    • Feri

      Nice wife. Impatient husband. Yes V3 should be higher. Those could be off as well, where most of them are without calibration or static weight test.

    • Luís Pisco

      Same situation with my gen 1 Kickr, about 20 watts higher than powermeter (around 250-2080 watts range), I use it with TrainerRoad PowerMatch and a set of PowerTap P1 pedals to control it.
      Accuracy issues aside how do you feel about the upgrade? Thinking about it but still not convinced.

  49. Grégoire Favre

    Would a Garmin 945 be able to control it in structured workout (setting the needed Power) also for doing an FTP test ?

    Thank you very much.

  50. David

    Hi,

    I’ve been investigating an issue/discrepancy between my Tacx Neo 1 and both my Quarq powermeters (Riken and Dzero) and came up with your page.
    The main thing I find weird is that the data recorded by Zwift if I connect my Neo as the power source is that it reads a bit higher than what is recorded by my Garmin Edge 500 connected to the Neo ANT+ power channel… I ‘ve also noticed that in one of your datasets in this article.
    I’ve contacted Tacx about it but they only say that the Neo reports power equally through both channels…
    Any thoughts or experiences on this?
    By the way the Tacx Neo usually reads around 4-5% lower than my Quarqs. The Quarq Dzero was recently calibrated using weights (the slope was adjusted 1% down) and is spot on (supposedly). On the other hand if I compare the data from the Neo from Zwift, it’s only 2-3% down from the Quarq.

    Sorry for the long message
    Thanks in advance

  51. Adam T. Klein

    I own the Neo 2T and use it with Zwift and Apple TV 4K and just love the setup. It is seamless and really makes riding inside a blast.

  52. HD

    Hey Ray. I was wondering if you’d experienced any power & cadence dropouts between the Neo 2T & Edge 1030 when doing an ERG workout?
    I’m on f/w 0.0.32 & seeing momentary dropouts every 3m30s whilst performing the workout. But if I load the workout & don’t press start I can pedal as long as I want without any dropouts. Once I start the workout & the Edge starts controlling the trainer the dropouts begin! It appearing as though the ANT+ FE-C on the Edge is somehow getting screwed up & doing the same to the power & cadence feeds

    • Hmm, I haven’t seen any dropouts. Is it just on ANT+? Out of curiosity have you tried BLE (just recording the BLE power stream to your phone using the Wahoo app for example)?

      3:30 is an odd timing. Usually when we see dropouts it’s almost always timed to something like the minute, 5 minutes, etc… I wonder if there’s something in your house that’s triggering on that kind of schedule, causing interference and the drop.

    • HD

      Hi Ray. Last night I tested the trainer with the Tacx Diagnostics app over BLE & my Fenix 3 paired to the Speed, Cadence & Power over ANT & I didn’t get any drop outs on either of these.
      The only difference I can see is the Edge 1030 is also has an ANT FE-C trainer connection to the Neo so I’m suspecting it may have something to do with that.
      I did think there may be some interference as I’ve a couple of other 2.4Ghz devices and did try switching those off, which didn’t seem to make any difference.

    • Yeah, I’ve often (like, weekly) seen cases where one unit will drop but another won’t. Sometimes it’s unit-specific, but oftentimes it’s just the nuances of interference.

      That said, for crazy-precise drops, having secondary sensors paired can also be helpful. For example, a HR strap too over ANT+. Often if a Garmin Edge unit (usually older though, not the Edge 1030) is having drop issues due to managing wireless load, it’ll drop all the connections at once – so you’d see HR drop as well.

    • HD

      I do have an ANT HRM paired & there’s no dropouts there. Strange that I’m not seeing any drops from the NEO speed either.
      Originally I only had the NEO paired as trainer sensor & although speed, cadence & power were displayed in the native Garmin datafields I didn’t get cadence or power in any CIQ fields only seeing speed so I also paired the Power & Speed/Cadence (no option to pair individually) as ANT sensors too, which restored cadence & power display in CIQ fields)
      I haven’t yet tested to see if there’s any dropouts if I remove the Neo as a Trainer sensor or remove the individual sensor pairings leaving the Trainer paired by itself, perhaps that’ll be the next step in isolating the issue

    • In that case, I’d get a case opened up with Garmin support (not Tacx support), so that they can start digging into the files (include your Edge 1030 file). My guess is given the specificity of it, they’ll escalate to engineering and probably get you an answer.

    • HD

      Will do Ray thanks for your comments

    • Ihsan

      Ray,

      I’ve found it to be edge 1030 specific. I have it paired as ant+ trainer, so it gets speed/cadence from 2T. Power is from pedals (I wish I knew how to force the 1030 to read cadence from the pedals as well).

      I see recurring drops both for speed and cadence. Timing is not a constant/set interval though, sometimes it’s every four minutes, sometimes less than that. Same ride recorded with F3HR (Neo 2T paired as power source) does not have any drops at all.

      All sensors connected are Ant+.

    • Hmm…so what you’re telling me is that I should finally get my Edge 1030 fixed so I can test this (the USB port broke about a year ago, too lazy to sort out)?

  53. Mihai Tintea

    Hello

    Is there a recommendation for the tightening torque of the QR adapters or the thru-axle adapters ? (see attached pic)

  54. Moritz Haager

    So I think I may have found a quirk in the Neo2T power readings when ground feel is turned on. In a nutshell it seems that the Neo2T reports a higher power than expected when ground feel is enabled, and that the magnitude of that effect seems to be greater the more severe the vibrations are. I tested the Neo2T against a Power2max (original flavor), Vector 3, and Assiomas. Originally I wondered if the accuracy of the Vectors would be degraded by vibrations causing the batteries to rattle but looking at this data I’m thinking it’s the Neo2T that reads high instead. My testing protocol was to turn the ground feel on at 1 Minute and then off at 2 mins, back on at 3 etc. I progressed from least intense (gravel), to hard cobbles, to cattle grid. I’ve taken a picture of each chart and included them here. Be interested if people agree with my conclusion, and if so I wonder why this might be the case.

  55. Alexis

    Ray,

    Good review, but let’s just be crystal clear, while they do provide L/R power, there are no cycling dynamics available in the latest firmware so far, it would be great to have some sort of ETA from TACX/Garmin….

    Another thing we all need to be aware of and maybe it should be included in your comparison table, Garmin does not care of their customer, zero customer support, maybe they are good with you Ray, but with us the mortal of this world, they just do not care, no answer to emails, calls of some sort, they even send you a survey email on how they do before they come back to you, oops right they never come back to you.
    I have multiple Wahoo products, now this is customer support since at least they come back to you within 2 business days, now true most of their guys are clueless, but…

    • I’ve long since given up on the idea of tracking customer service, as it often varies heavily by country.

      That said, while Garmin has many issues, it’s very rare people complain about their support team. At least in the US and Europe. Like, super rare. And even more so as they’ve taken over Tacx, I’ve heard almost no complaints but the opposite – people much happier than before.

    • Alexis

      Umh, I am in the US, and all the people I know complains about their lack of support, even on Facebook, the only major issue with them is lack of support.

      You are the lucky one here.

      I have sent them five emails and left two voicemails regarding an issue with the Neo 2T, still waiting for a reply as an example.

    • Well, I’d never recommend using e-mail support with any company. Just always sucks. Frankly, Facebook support is the same. It almost always for every company since it’s nearly impossible to track and do historicals well, except for real-time quick back and forth easy troubleshooting things.

      But, for phone support, again, the overwhelming vast majority of people are happy based on the comments I see daily. Not really sure what else to say.

  56. Sathya

    Can I use the device with pacemaker implant?

    • Moritz Haager

      Hmmm. That’s a good question. (I’m an ER doctor for background). Theoretically its right to be concerned about strong magnetic fields with Pacers. Intuitively I’d guess it’s not strong enough in this case, and to far way from your pacer to be of concern but I can try and find out. Might also be worth shooting Tacx an email to see if this has ever come up. You’d think this kind of thing might be included in getting certification for the electronics and wireless emissions.
      Do you have a simple pacemaker or an AICD (implanted defibrillator)?. Good news is that usually applying a magnet to a simple pacemaker causes it to just pace at a preset rate without any regard for intrinsic cardiac activity. In AICDs however in think it’s more complicated and can turn the defibrillation function off which would be suboptimal if you’re exerting yourself and go into a lethal dysrhythmia as it won’t shock you out of it.

  57. Zola

    So what unit will be better for slow speed heavy riders? 230 lbs? Been looking between 2T, H3 and Kickr and maybe Diretox. I’m scared with kickr complaints and problems people have had. Appears GpLama and DC say that it really is not that bad. I’ve given up on elite suito….. what is best for heavy riders?

  58. Aleksandr Dorofeev

    Neo 2T was the biggest disappointment for me. I upgraded to disc brakes and also upgraded my Neo 2 to Neo 2T. So. I found that 142 adapter with provided spacer gives 144.7 mm rear spacing. This may compromise frame integrity and cause accident and injury. So. I bought trainer from another brand and requested return.

    2T is one of the biggest engineering flops if tacx. Despite of this is perfect and precise trainer with plenty features. But the best way for tacx reputation is request to stop to use this trainer with spacer and initiate recall/replace 2T.

    • John

      Recall the trainers because, although they work perfectly and fit most every bike, yours doesn’t fit? Suuuure. The provided spacer should work, or you can just loosen your brake caliper bolts so it slides over. It’s on the trainer so it doesn’t matter, and it’s quite easy to reposition brake for outdoor riding. Maybe not the ideal solution, but I’ve seen you post everywhere about recalling and how horrible this product is, and it’s quite over the top. Chill out, go get a different trainer if it’s so important to you.

    • Aleksandr Dorofeev

      Not fits – I’m suuuure. SRAM Red AXS calipers rubs against trainer housing. Both Gen1 monoblock and Gen2 2-piece. Loosen-shift-recenter was permanent pain and not superhealthy for calipers and frame. Trainer changed. New works better: more natural and quieter. Also normal 142 O.L.D. eliminated drivetrain vibrations and noise.

      Yep. Neo 2T is dangerous. I don’t see any notes about increased spacing in reviews or specs. This information is important.

  59. Mihai Tintea

    I have the Neo2T (w/ the latest firmware) , I haven’t had any grinding noises or anything similar yet, but I also have the original Kickr 2014, and I must say that the Kickr is far superior when it comes to ERG mode workouts.

    The Kickr responds quicker and far more precise to resistance changes.

    The Neo2T has big delays to resistance changes, and with a minimum 10% error in the obtained wattage. By the time when the workout segment with the requested wattage is over, the Neo2T barely had time to hit the target wattage once, and even then it oscillates around that value several times before it keeps under 2% wattage difference from the requested target wattage.

    The Kickr allows me to pedal on the small chainring and largest cog for a far wider wattage range, whereas the Neo2T needs me to constantly shift through chainrings and cogs before it is able to keep the target wattage (with the huge errors mentioned above). So instead of minding my own business about the ERG mode workouts, I constantly have to shift up and down until somehow I make the Neo to sit somewhere around the target wattage.

    So far the Neo2T is a huge disappointment to me. If I knew how it behaves, I wouldn’t have paid not even $200 for it, because of the frustrations it gives. Too bad the in-depth review on this website is misleading.

    • Mark Put

      I also have the Neo 2T, but I find that the ERG mode works fine. I don’t have to shift at all.
      I find it responses quickly, sure it needs a second to settle into the new target wattage, but that mostly depends on the slight change in cadance.
      My guess is that you are not in ERG mode, otherwise shifting shouldn’t be necessary.
      If not, your 2T is defective, and should be returned for repairs.

    • Aleksandr Dorofeev

      Yep. I changed Tacx NEO 2T to Wahoo KICKR 4.0 (2018) due spacing and clearance issues. So I have experience with both. KICKR is quieter, smoother and responds faster. Also I found that “superfeatures” of Neo 2(2T) is just gimmick and pure evil. “Road Feel” is not vibration but force applied to freehub. This ruins drivetrain. “Descents” makes sense only in tacx app.

    • Mihai-

      Hmm, I don’t understand why you’re shifting in ERG mode. You’re the first one to report issues beyond that I outlined in the review, with respect to ERG mode (I noted it was a bit aggressive actually – the opposite of what you’re saying). Which generally means, in my experience, that either something is defective with your unit, or there’s some misunderstanding of how it’s suppose to work – as Mark noted above.

      Aleksandr-

      Honestly, you’ve stated a lot of funky stuff in your comments here over the last little one. Most of which doesn’t really make sense. There’s no ‘ruining’ of the drivetrain. This tech has been around for like 3 years now, and nobody – not even Tacx’s competitors or bike companies – have said that.

      One spacing, again, nobody has had issues like that. As others replied back to you above, what your saying indicates something very specific to your specific frame, or some sort of installation error on your bike. 142 is 142. If you don’t have 142, then using 142 spacing obviously won’t work. All of which has nothing to do with brake calipers. And none of it has anything to do with integretity of the bike unless you’re doing something to your bike you’re not supposed to by using the wrong parts.

      And as others have noted – you’ve plastered this every place you can find on the interwebs, and everyone has told you the same thing.

      Look – my point is simple: There’s enough to be annoyed on the NEO 2T about already, without making stuff up that just doesn’t exist (I don’t think MIhai is making stuff up, I think there’s just some confusion or a legit defective unit).

      Cheers.

    • Aleksandr Dorofeev

      142 mm on bike
      142 mm on my rear wheels
      142 mm on another trainer
      144.7 mm on Tacx NEO 2T with 142 mm adapter and 2.7 mm spacer.

      It’s numbers. Neo 2T does not comply with the elementary standard. If I were you, I would be afraid to ride a bicycle on the road, the dropouts of which were subjected to stresses for which they were not intended for a long time.

    • R Foulkes

      Is your bike made out of something brittle?
      Last time I checked, both my aluminium and carbon fiber frames flexed way more than 1.35mm during riding.
      Come to think of it the frames tend to flex inwards when you tighten the axle. 2.7mm between two rear stays is SFA IMO.

      I guess if you’re worried about drive train wear due to the roadfeel. Well…………

    • Mihai Tintea

      Hi

      Thank you for your feedback. However I know very well how ERG mode works in trainers. There are plenty reasons for shifting. For instance, the Neo2T is incapable of providing 240W of resistance if I am on the small chainring+largest cog+low cadence. It tops at 160-180W. Therefore I have to get to a smaller cog if I want to keep the low cadence. The reasons I want to keep the low cadence are many. For instance I want to do muscle tension. Or I am 50yo and I am tired and I am incapable of using a higher cadence unless I am willing to cut my workout short. Which I won’t.

      But of course you know all those things.

      Bottom line, the Neo2T is not that good. The marketing is strong anf full of tricks. And your so-called in-depth review is misleading. Reading it, I thought the Neo2T was the Messiah of the smart trainers, the best of the best and so on and so forth.

      Which is not.

      Please accept this reality about your review. Which is not the first one that misfires. Remember the one about Wahoo Strava Segments app ? Being “worth” $30 ?(!) That review started me pumping big $$$ into indoor training stuff. Such as: the Kickr 2014, iPad, lots of apps, clothing, shoes, smart watches, head units etc.

      Best regards

    • Moritz Haager

      Yeah I’m gonna say there’s something wrong with your Neo2T, or something else is going on. I have had my Neo 2T able to hold 230 to 280W at cadence of 50 to 60 rpm in the easiest gears for 1 to 2 hrs steady, and ramp to to around 340 watts on simulated climbs repeatedly over the last several weeks. It’s also super close in watts when compared to my Power2max and my Assiomas. Happy to share the files too. So if yours can’t hold 180w then it absolutely must be defective and I would get it warrantied.

    • JD

      Mihai —
      There shouldn’t be a need to switch gears to complete an ERG workout. Perhaps you have the wrong FTP setting or your unit is defective. Or you are confusing resistance mode with ERG mode.
      The only legitimate reason to change gears in ERG would be to limit flywheel speed at the beginning of a workout. Otherwise stay in the same gear if you want to complete the ERG workout as designed. If you can’t complete an interval then back pedal until the end that interval. Or lower the % intensity of the workout.
      In either case downshifting in the middle of a ERG workout makes no sense. All that does is tell the trainer to readjust watts back to the level defined for that interval.

      As far as “muscle tension” goes if you want to build leg strength I think you’ll derive more benefits off the bike — lunges, lifts, stairs, etc. with or without weights.

    • Mihai Tintea

      Well, I’ve opened a case with Tacx/Garmin support.

      I told them that I am utterly disappointed and frustated by the accuracy% of their product. Maybe the accuracy% drop is caused by the overheating process that comes from the cadence sensor — this is an issue that Tacx has publicly acknowledged.

      The trainer’s electronic motherboard is overheated by the cadence sensor circuit. The result is that the entire trainer electronic goes nuts and the trainer has to be powered off and restarted.

      They (TACX) said that somehow the newest firmware 0.0.32 (or so) fixed the overheating issue, however I have a grand disbelief in such solutions. Poor circuitry is poor circuitry, the same way that a circle is round, and that’s that.

      The Original 2014 Kickr does not have such problems. That trainer behaves like an angel.

      Literally.

      I can throw at it whatever combination of cadence+target wattage I want, and it delivers with the documented accuracy , within 1-2 seconds.

      I can shift to whatever combination of chainring/cog I desire, anytime during an ERG workout, because of reasons. For instance, noise of my drivetrain.

      The Original 2014 Kickr delivers the steady wattage within 1-2 seconds at most.

      Whereas, the newest and the greatest trainer of them all, i.e. the Neo2T, oscillates the effective wattage up and down by at least 10% around the requested target wattage, for at least 5 seconds, before the trainer stabilizes within a 3-4% wattage error. That is utterly sadistic. Miles away from the advertised 1% accuracy. For an 1300Euro product.

      Mihai, Are you sure you aren’t comparing the power measured by the Neo to the target power a Kickr displays? I seem to remember by default a Kickr shows a perfectly flat line corresponding to the set target power for an ERG mode instead of the actual power you are generating. This can give a false impression of accuracy.
      I can’t comment on your other issues, but I’ve not seen anything like it in my usage both in ERG mode and ‘simulation’ mode (or whatever you would call cruising around zwift).

    • Mihai Tintea

      Hi Paul

      I use PerfPro Studio, this software shows as solid histograms the target wattage from the workout’s scenario, and with thin lines the actual recordings generated by my legs.

      If you have Sufferfest, you can think of how the “Violator” workout is totally ruined with the Neo2T in ERG mode. (if you do not have Sufferfest: this workout has 5 second sprints at 190% FTP – figure that out)

      When executed with the Kickr, this workout in ERG mode is done exactly how its authors expected.

      Best regards
      Mihai

      Apparently 0.32 F/W has not fixed the overheating issue for everyone:

      link to tacxfaqx.com

      I also noticed that the unit is on back-order through some retailers. I was planning to purchase a Neo 2T but will delay doing so until there is no question that the issue has been resolved and, if needed, the pipeline has been refilled with updated / re-worked units.

    • John Reinke

      The latest firmware is 0.34. I’m not sure if the latest update addresses overheating, and I don’t know that firmware can fix something which sounds (to me) to be a hardware issue. If you receive a unit which overheats, it sounds like Tacx/Garmin support is very good.
      I’ve had no issues with my Neo 2T, and I train on it as much as 1.5 hours at a time. If you truly want to get the trainer, I’d say go for it!

    • Don

      Thanks, John, I’ll likely give the Neo 2T a shot.

  60. Joan Alcover

    Just received my NEO 2T smart. It replaces a Genius “non smart”.
    Night and day! Not only the silence: power delivery is much smoother!

  61. E. Felkerino

    Ray,

    can you address any noise & vibration from the fan and motor on downhill segments in Zwift? On my Neo 1 it is fairly noticable coming down from a long ascent like the tower summit or Alpe (but not on smaller hills). I’m thinking internals get hot on long slog uphill and then have to be cooled even more when the motor kicks in.

  62. Felipe Serra

    Ray, but according to your powermeter test, the numbers are far away from de +-1% accuracy that they claim. i’m right?

  63. Jeremy Williams

    Do you know if the clearance for disc brake callipers has improved? On the Neo 1 it was very tight.

    • John S.

      It’s quite tight on my Trek Domane Disc frame. But it works and I just do a quick adjustment before I road ride the bike…

  64. Marc-Andre Savage

    I have just purchased a Neo 2T and I am trying to reconsile the power number differences between my single sided 4iiii Precision and the Neo. I recognize the limitations of single sided powers meters (Leg Power Imbalances) and that drivetrain power losses are to be expected, but a 13.5-15% difference seems like a lot.

    link to analyze.dcrainmaker.com

    Both units are running the latest firmware and the 4iiii was calibrated before the ride.

    I know the Tacx is reportetly the gold standard for trainer power for accuracy but 5 years of power data with the 4iiii has me questioning the spread. The Precision data has never prompted me to question its accuracy when I analyzed its output compared to other riders, expected power output on a given hill climb, rides on other trainers, etc…..

    Tacx support has asked me to provide more ride data but they seem confident that every Neo that comes off the assembly line is dead accurate. No comments from 4iiii yet.

    Are there any methods to validate the Neo’s accuracy aside from sourcing a set of power-meter pedals?

    • Felipe Serra

      On the link which one is the tacx and which one is the 4iiii, what apps do you use to record?

    • Marc-Andre Savage

      The first file (higher power numbers) is the 4iiii output recorded from the native 4iiii iPhone app. The second is the Neo 2T recorded in Zwift.

    • Felipe Serra

      OK. Really don´t know what’s going on, but is worrying

    • Moritz Haager

      I have the 2T, assiomas, a original Power2max, and a single sided 4iiii mounted on the drive side. The 2T and the Assiomas are basically spot on. Usually the average power on rides is different by one watt and i have done the visual comparisons of the curves in excel as well. The P2M tracks a little lower but is still close. I have not done a comparison with my 4iii yet as it’s on my MTB and I have been too lazy to switch out the cassette etc. I had compared the 4iiii to dual vectors on the road before and the 4iiii was high relative to the Vectors (which had their own problems). Part of this was likely that I have a bit of a power imbalance (usually 47% left 53% right) . Since my 4iiii is mounted on the drive side it makes sense it was reporting higher power. I adjusted the scaling in the 4iiii app to account for this and at some point plan to do a direct comparison with the bike on the 2T. Once I do that my plan is to fine tune the scaling in the 4iiii until it is a close as possible to the 2T. I think that the single sided PM makes it more challenging to compare. The Tacx Neo 2T gives you power balance BUT i have noticed it gives me the inverse of what my Assiomas (and my Vectors before that ) report i.e. the Neo says my left leg is providing more power whereas the other 2 always say my right leg is more powerful which i think is more likely since I’m right handed.

      As Ray has often said its impossible to know which power meter is actually “right” but i think it’s more important that the powemeters you own agree with each other relatively well so that you can use the data from each easily.

    • Marc-Andre Savage

      Thanks for the reply Moritz. I’m would be very interested in seeing how your 4iiii matches up with your Neo 2T. Today I recorded another ride with the with my Garmin, Zwift and 4iiii Iphone app. My recorded leg imbalance was 51% Left / 49% Right. The power difference was still 13.5-15%.

      Assuming 2% loss because of the leg bias and a 3% loss for the drive train, there is still a 10% difference. I’m fine with adjusting the scaling on the 4iiii to match the power on the Neo but I’ll always wonder if this $2000 machine is out of spec. That and I can no longer ride with my regular local crew because I can’t hold a wheel on the climbs. 🙂

    • Moritz Haager

      If you can borrow a third power meter, ideally pedal based, to compare all 3 I would do that. I think itf 2 agree well and one is off then its a reasonable assumption that the odd one out is the weak link so to speak.

      Also I’m assuming you have updated all your PMs including the Neo to the latest firmware.

    • Ross F

      Marc-Andre Savage, have you tried recording an interval using one leg only on the 4iiii?
      I have used this method with 2x Stages units and found them to be incredibly similar. (See attached image).

    • Felipe Serra

      You can do an erg test and no cassette switch is needed, is your transmitions are 11s.

    • Marc-Andre Savage

      I had another chat with Tacx support. They are having me run a diagnostic test and I will try a few things mentioned here. I would love to get my hands on another power meter as a control…

      One curious thing that stood out in the files I recorded with my Garmin 520. The speed reading kept dropping out while the cadence and power reading were rock solid. The Tacx support tech though it was odd but said I could be interference. He didn’t rule our that something might be off with the unit.

  65. Anyone had their Tacx Neo 2T temporarily not work in ERG mode in a workout? I was starting a workout today and it just wasn’t working… Resistance all over the place.. After about 10 mins riding, few reboots of trainer, zwift and PC it eventually said “erg mode temporarily disabled” in Zwift, I got some random road feedback where I shouldn’t and then it came good…

    Setup is ant+ sensor into Windows 10 device… Had all worked flawlessly for the past week and the workout was a standard recovery one I’ve done a few times…

    Any ideas appreciated… Don’t want it to happen when I’m. Pressed for time or mid workout…

    • Update it. Same problem. I just have a like-minded neighbor, who’s pain cave shares a wall with mine and she has managed to connect to something in my setup! Troubleshooting to begin on what exactly (I think something Bluetooth to my trainer as I use Ant+ but have trouble connect f to the Tacx app).

  66. Mark

    Hi,
    I own an Neo 2T since october 2019, and recently bought a power2max NG.
    When I tested both, I noticed quite a difference in numbers. The P2max overreported consistently.
    I did an interval training from trainerroad in ERG mode.
    I used a 22 chainring with the middle of a 10 speed cassette (mtb).
    At first the P2M NG gave 5 to 6% higher readings, but when I shifted gears to the big chainring and smaller sprockets, the difference shot up to 10-12%. I kept the cadence similar.
    You can see the gear change in the last 2 intervals.
    Because a different chainring only (mostly) affects the Neo 2T (bigger flywheel speed), I guess it’s the Neo that started to fail accuracy.
    In the picture you see the 30 second smoothing of the powermeters, Neo2T Yellow, P2M NG Red.

    • Mark

      And in this picture you can see the actual difference in Watt’s (blue and left axis) between 7 and 23 watts.
      The difference in percentage (black and right axis) is at first quite steady around 6%, and shoots up to 10-12% once I changed gears.

    • Marc-Andre Savage

      The relation between flywheel speed and accuracy is very interesting. I am seeing mysterious speed dropouts when recording with my Garmin 520 at one second intervals. (see post above) I am wondering if perhaps there is something wrong with the flywheel speed sensor or firmware.

    • Mark

      I did two new tests, this time with a 1×12 drivetrain, (32 chainring and 28 cog) so the rpm of the neo are about the same as my cadence.
      First picture is a ramptest, and both powermeters (neo 2T and power2max NG) are most of the time within 1 or 2%. This is, in contrary to my previous test, almost spot on. Only on the cooldown portion you see the red (p2m) and yellow (neo 2T) line deviate (both are 30s average). The grey line shows the difference in %, the blue one actual watts (right axis)

    • Mark

      And this is the second test, some over unders 15 to 25 seconds, up to 325 watts.
      They track also quite good, but the difference shows a bit more, especially at the start and end of the intervals, which I understand, once it stabilizes, they’re again within 2%.

      My conclusion is that with the Neo 2T you need to ride in a low gearing if possible, because when the RPM of the Neo2T ramp up, the powernumbers are way off.

  67. Eric Olsson

    Really useful review, thanks! I just bought the Tacx Neo 2T to give me a good workout option during stay-at-home orders. Thanks for justifying my purchase after the fact 🙂 You included a lot of information that will be very useful for tweaking settings and so forth as I get used to the new gear. I’m new to trainers generally but really like the new Tacx apps with simulated rides. Happy to subscribe to your newsletter.

  68. Chaz

    I’ve just managed to buy a new Neo 2T as a replacement for a Tacx Flow I’ve been using. Overall it’s really impressive but I’m experiencing one thing that surprises me – at very high resistance and relatively low power, say for example on a 10%+ gradient when the app is simulating 100% difficulty, the pedalling gets really rough and lumpy. All other times it’s nice and smooth.

    Has anyone else experienced this?

  69. Tim Mitchell

    Just to add my experience with the Neo 2T as a UK based user. I purchased the unit direct from Tacx’s website in September ’19 as a subsidised warranty replacement for an inaccurate Flux 2.
    Since then it has been used 3-4 times a week for structured training on TrainerRoad. I did have a spell without training during January and February, but hit it again as Covid restrictions came into place.
    The unit failed on 5th May – it overheated during a low intensity workout and is now unusable. Every time I start a workout it overheats again within 3 minutes – causing a burning smell and all resistance to drop away.

    I have been in contact with Garmin, they have agreed to replace the unit, but are insisting that I pay the shipping costs back to their UK centre. The best quote I can find to ship this unit back to them is £70 (including insurance). I really don’t think it is fair to ask me to pay this. The unit has failed within 8 months.

    I have heard that other Neo 2T owners in the UK and EU have received a free return shipping service from Garmin, I am not sure why some owners get this and others don’t.

    While it was working, the Neo 2T was a great trainer – it tracked almost perfectly with my Assioma pedals and felt great to train on. Obviously I am really disappointed with the service levels from Garmin so far, I hope they soften their stance and can arrange to collect the unit from me.

    • Tim Mitchell

      Update: Garmin agreed to offer free return shipping of the unit. Unfortunately I’d lost patience and already shipped it back to them!

    • John S.

      I had the same issue and they initially wanted me to ship mine back (presumably paying for the shipping myself) and then they would ship me my replacement. I pushed for expedited shipping and pre-paid return and got it from them. This was in the US, but I’d urge all customers who experience this problem (which I sure hope they’ve fixed!) to do the same.

  70. Vicente

    I have a Neo 2T since January. I’ve been following the comments here, and read some complaints. I am sure that the vast majority are totally legitimate and justified. But I have thought that as in other cases that I know, only negative experiences are discussed in posts like this. So I thought it might be useful to share my experience. No problem, using it almost daily since January on Zwift and Trainerroad. I intend to compare the power readings with my Assioma duo, but haven’t found time yet. Too many routes and events in Zwift ….

  71. Marcel

    Has there ever been a definitive conclusion if bottom bracket height and chainstay length have anything to do with cadence problems? I bought a Neo 2T in late December, and used it a little bit in January prior to getting distracted by the ski season. I am a newbie to smart trainers, and primarily am a mountain biker. I have only used it with Sufferfest. I immediately found that using ANT to control it in Sufferfest was not workable, as there were 5-8 second delays for changes in resistance. That seemed to be specific to Sufferfest in Windows, judging from posts on their forums.

    So I switched to BT to control it instead. I’ve been using it frequently the last 8 weeks or so, and have found that it frequently drops BT connection and erroneously reports cadence. I have done everything I can to clear up interference, including turning off my wi-fi, changing channels, having the BT dongle on a USB extension a foot from the trainer and the like. In the last couple days I have come to realize that at least the cadence issues are definitely caused by heel position. If I consciously keep my heel dropped in my pedal strokes, it seems to pick up my cadence consistently. If I lift my heel purposely, it almost immediately starts reporting very low or no cadences. Whether this is related to the outright connection drops, I’m not sure. It does seem that if the cadence is being reported wrong, that after a few minutes the BT connection will sometimes drop. Outright connection drops happen once or twice during every other training session, roughly. But like I said, the bad cadence reporting I’ve found in the last couple rides is entirely controllable by my heel position.

    I’m using a 2017 Giant Anthem SX on the trainer. Don’t laugh, that’s the only bike I owned until recently. I did pick up a gravel bike a few weeks ago, but my intent was to commute with it, so not sure I want to order another cassette for it, as I’ll be pulling it on and off on a regular basis as opposed to every now and again with the trail bike.

    • John S.

      Marcel, It sounds like you’re having a problem similar to what I was seeing my mine. Contact Tacx/Garmin support. They have a plate that you can strap on the end of your left crank that will accurately trigger the cadence sensor. (Or you can make one out of sheet metal like I did…) Good luck.

  72. Thank you for the great review. It helped me to decide to purchase the Neo 2T to replace the Kinetic R1 that I returned. (Wish I’d read your review of the R1 before I made that mistake.) And other than the issues below, I really like it a lot.

    Three quick things: 1) my Neo 2T burned out after about three weeks or so of use. And no, I’m no beast – my FTP is in the low 200’s and I ride less than a hundred miles a week. Tacx/Garmin support didn’t seem at all surprised by the failure and immediately sent me a replacement. I literally wrote four sentences on their tech support chat and they told it it would need to be exchanged. So it seems clear they have seen this problem before. Have you heard of any issues with Tacx NEO trainers? I’m hoping this isn’t a trend. The replacement arrived a few days ago and so far it’s fine. But then so was the first one……until it wasn’t.

    2) It’s quite disappointing that a $1400 top of the line trainer doesn’t have leveling feet. Who has perfectly level floors? So I purchased some that turned out to not be quite the right size, but I was able to modify them to fit. They work perfectly and look as if they were truly designed for the trainer. I’d be happy to send you info and photos if you’re interested in sharing this with other Tacx owners. I have no financial gain from this. I’d just like to get the solution out there for those that might need it.

    3) The replacement Neo 2T couldn’t quite read my cadence accurately. (I had no issues with the first one.) It would mess up every few seconds, and as a result the power was off too, which in turn messed up ERG mode. Quite a mess. They sent me their cadence trigger plate that you attach to the left crank with a rubber band, but it interfered with my Pioneer power meter, so I made my own plate from some sheet copper I happened to have. If one has the tools (just sheet metal scissors) it’s a super easy thing to do. I tucked it under my Bontrager cadence magnet strap and it works perfectly. Again, happy to share photos…

    But like I said above, other than these issues, I really like this thing. Thank you for the work you do!

  73. Chris Pidgeon

    Hi, just ordered one as an upgrade to my Magnus.
    Anyone any ideas when/if Bluetooth FTMS will be coming to the NEO Series?

  74. CowRob

    I received mine in early November, and apparently from day one, the bike wasn’t level on it. (I was so excited to have this new trainer, I swapped quickly) After finding a piece of blue plastic on the floor recently, I started investigating, and rediscovered the out of level issue, and put the left side up on two blocks, and opened a case with Garmin. They replaced it, which was awesome. Since I had it up on the blocks, my back issues have disappeared. I should have investigated and opened the case with support sooner. But whatever. My pictures are in the earlier DCR post announcing the 2T.

    After taking my bike off, during cleaning to ship it back, I discovered a lot of cracks in the blue plastic on both legs. The piece of plastic I found is from the bottom corner of one of the legs, where the folded steel substructure ends just past the foot. The other cracks are mid span of one ‘strut’, and spread across mold lines near the feet, and one at a screw that goes into the substructure.

    I’m not reporting this to rip the 2T, but suggesting that people that have one look into whether their bike is level, and also remove their bike and check the legs and ‘struts’ where the substructure runs down from the hinges to the feet to see if there are any cracks.

    I weigh less that 200 pounds, so I doubt that this is a weight issue. According to Garmin Connect, I have about 3,400 miles on it. One thing I noticed is the packing material has changed from the first one I received and this replacement. They went away from a standard Styrofoam packing to a denser coated/mixed Styrofoam. The foam at the bottom of the original was busted in several areas, so I wonder how much shipping stress it had coming from the factory to me. Plus how much the side to side movement possible while riding is causing stress to transfer into the struts and that is causing the cracks.

    I’d be curious if others have any cracking. Hopefully Garmin can/has fix the issue.

  75. Santiago Cerrilla

    Hi Ray, thanks a lot for the thorough review. After reading it I decided to take the plunge and get a Neo 2T as it seems the most complete con the market (although the most expensive one.

    Comparing the power readings on the unit to my Vector 2 pedals I see the Neo being from 3% to 10% lower (ERG and Free Ride on the higher end of the range). Would you think this is acceptable or should I try to get a replacement unit to be closer on readings.

    As always your reviews are super helpful and worth while.

    Santiago.

    • Eric

      Hi Santiago,

      I don’t have an answer to your question, but wanted to let you know that Tacx is on Facebook and has been very responsive there. “Like” the Tacx page, and join the “Tacx Apps” group. “Tacx Apps” in particular seems to answer user questions very quickly.

      Cheers,
      Eric

    • CowRob

      When I raised inconsistencies with Garmin, I was told that the Neo 2T was not capable of being off in its power readings. It had to be the power meter that I had, a PowerTap C1. Part of their comment was that the two devices were reading the power from two different methods, and there would be a chance for discrepancies, but that the Neo 2T was accurate for the method/way that it was being measured.

      I guess I wasn’t surprised by their response. I chronicled the conversation in either this thread, or the other one. I felt like I was brushed aside, but after fighting with three different power meters, one calculated, I have come to the conclusion that ‘accuracy’ is as good as it is said to be. So many are different, and none seem to be spot on, or within any stated accuracy range compared to each other. How can you prove that the Neo 2T isn’t accurate when the accuracy of everything that you can use to prove its inaccuracy is potentially inaccurate as well. It’s like hitting a moving target. I gave up on trying to prove that the three power meters weren’t accurate. In the end, it didn’t matter as much as it would take to accurately prove that the individual meters were accurate.

      Plus, would Garmin want to be in the position of proving that either the Vector, or the Neo were wildly/moderately inaccurate?

    Thanks for the review – can you elaborate the paragraph “ Next, while Tacx does have a mobile app for their trainer, it’s unlikely you’re going to use it much if you use other 3rd party software. However, it is valuable for setting your correct weight so that you can get realistic grade simulation (as well as firmware updates). This is notable if you’ve got multiple people in your household at dramatically different weights:”

    Doesn’t apps like zwift send the rider weight to the trainer with the incline

    • One would think…but nope.

      It’s a long-standing quirk. It would be immensely better if they did.

    • CowRob

      I just think it’s like the H2 I had, and having to use the Rouvy Windows app to calibrate it. Strange, especially after they did an update to the app. ‘Where did they move that to I wonder?’

      Not having to calibrate is a blessing.

    • John Reinke

      Really? I never realized this. I don’t think I’ve ever updated my weight in the Tacx app since I set it up, but I’ve updated it in Zwift and everywhere else.
      So, unless I change my weight setting in the Tacx app, the Neo will apply the same amount of resistance for a given hill in Zwift no matter what weight I enter for myself into Zwift?

    • Paul

      Same for me, I set it once and never touched it but my weight in zwift is linked to a withings scale.

      I assumed zwift told the trainer how much resistance based on in game terrain and stats.

    • Nope, at least not with Bluetooth Smart connections. I was chatting with 2canbazza afterwards via e-mail, and he correctly pointed out that for ANT+ FE-C it will send it to apps (and apps will honor it), but not for any Bluetooth Smart connections except Tacx’s own app.

      Note that this only really impacts the Tacx NEO, NEO Bike, and Wahoo KICKR Bike – all of which use the same electromagnetic flywheel design that needs to know your weight to replicate it correctly. It doesn’t impact your Zwift power output, but impacts how realistic the NEO feels.

    • CowRob

      I’m having a hard time realizing what the effect would be for having ‘bad data’ in mine, and the bike weight fields.

      I checked mine yesterday, and it was set to 75 and 10. I’m actually 88.5 and the bike is 8.6. I made the change, but don’t know if there was a noticeable difference.

      So, did I just made climbing harder, yet not as much because the bike is lighter?

    • CowRob

      And I Googled around for enlightenment, and found that ‘most people’, apparently, seem to ride at a ‘trainer difficulty’ of 50%. Why? I ride at 100%. Am I working too hard? I started at the ‘default’, which seems to be 100%. It doesn’t make sense to alter that, unless I’m dying during a programmed workout.

      I think I missed something, or I’m a masochist. Um…

    • 2canbazza

      RobCrow

      Zwift trainer difficulty is set to 50% by default and has no affect if doing a workout (since incline is not in play).

    • Konstantin

      I’d like to confirm this for other people who might have found this post and wondering what effects this might have while using the trainer.

      I share a Neo2 with my wife, and its had a set weight of 80kg since day 1, until a few days ago when I found a post about this in a Facebook Tacx owners group with the screenshot from dcrainmaker with a comment above. My wife decided to test it yesterday and set her weight in the tacx app and off she went to use zwift doing alpe du zwift, and while the watts were the same, the climbing felt much easier for her (over 30% reduction in weight setting). She had told me before that zwift felt much harder than outdoor riding but I didnt know what reason could there be since she had all her settings correctly in the app and I never suspected the trainer sending other data and overriding the app in use.

      I use an ant+ usb dongle with my pc because its an old laptop with bt3 and most apps requiere bt4 so I have to use ant+, another reason is to have the heart monitor and her speed/cadence sensors that dont use bt.

      Today I forgot to set the weight back up and I did the same workout as last saturday, all numbers except heart rate and relative effort were basically identical. I generated the same watts and cadence, but my heart rate averaged 14 bpm lower for the whole workout and it made it feel noticeably easier.

    • Anthony G

      Can you perhaps update review to make this clearer? Later in the article you say their own Bluetooth protocol is used in Zwift as the standard one doesn’t support weight (which strongly implies Zwift is actually transmitting the correct weight…). Based on that I have not been updating it, and making my much lighter OH work harder than she should…

      Thanks for the great site and reviews!

  78. Howie

    In Tacx app version 4.9.3, I can’t find any way to check, let alone update, the Neo 2T firmware.

    • CowRob

      You have to connect through Bluetooth, and nothing else can be connected to it. It’s often the case that people don’t realize that the trainer is connected to their notebook, or other device already, and can’t be connected to their device for update. I’d recommend checking what might be connected to it already, and either ‘forge’ the trainer, or turn it off. I’ve had that happen myself, not realizing how quickly the computer grabs the trainer.

      Good luck…

    • Howie

      Doh, I was in the wrong Tacx app (Training vs Utility). Three apps (Cycling, Utility, Training) and now with Garmin (who has yet to make user friendly software) in charge of Tacx. Sigh.

  79. Peter Sorantin

    I am currently looking at the Neo 2T – my question:

    I am riding a custom frame titanium bike (bought from a friend who put it all together) that has a 10-cog Campagnolo unit, named “Record”. Seems to be from 2010.

    What do I need to do to make this work on the Neo 2T?

    I was originally planning to get the Wahoo Kickr, but their Camapgnolo adapter has terrible reviews (actually on their website, saying its not really working).

    Maybe folks here can comment on both units regarding how to make it work for my Campagnolo gear…

    Thanks!

    Yesterday I tested tacx neo 2t (I’v waited a lot for this) and … is very very dificult mantain power, compare with my previous trainer (tacx genius smart). Compare power measure between tacx neo 2t and quarq power meter in my mtb … 10 – 15% accuracy. I’v installed firmware 0.0.36 … I read a lot in this site and other, I think that my unit have some fail , or the firmware have bugs. I have mac pro 2015 with zwift, connect with bluetooth to neo.

    Please, Some could help me with some workaround or experience.

    Thank a lot (my english is bad), from Chile.

    • Do you have any files to compare (meaning, full recorded files side by side)?

      Also, keep in mind that you probably have smoothing enabled on the Zwift app (and maybe on your Garmin). Here’s something to help a bit: link to dcrainmaker.com

      thanks a lot, it information is very usefull, in the afternoon I’ll test that it (20kg test in my quarq xx1).

      I’ll record tacx neo2t with quarq xx1 in some ramp test, and compare the output and share with you.

      Hi,

      Yesterday I compare tacx neo2t with quarqxx1 eagle, firmware update in both, chain very clean and cassette (new) in mtb mount it in tacx. I used tacx trainner software in iphone, and garmin 520 plus for capture data from quarq. I programed a converted (in java language) for read tcx and add offset if it is necesary. 5 min aprox of test, the results in

      My resume: mmm 10% accuracy is bad, it is very responsive, I believe that 3% is good.

    • Hmm, yeah, that’s pretty far off indeed.

      I wish I had a good answer/option there. Any chance you’ve got a friend with a bike and power meter that can be placed on there to validate?

      With only two units, it’s hard to know which one is right. :-/

      Very very interesant test, with tacx app and garmin 520plus (connected with quarq).

      Other test was in zwift, neo 2t power meter connect with garmin ble, and zift connect with quarq as power meter and cadence sensor, in erg mode.

      It is very rare! maybe is possible an issue with bluetooth. I will try connect again al publish the result.

      If the difference is proporcional %, then slope quarq could be root cause …
