Eurobike 2022 Tech Tidbits: Bryton Trainer, New Stages & Rotor Power Meters

I’ve got a few minor tech tidbits from Eurobike still to sprinkle out in some posts. While this wasn’t a big show for indoor trainers/bikes from the bigger brands, there were a surprising number of smaller brands showing off new trainers. Some at the show, and some not. And the same goes for power meters. No major new power meters were announced at Eurobike, but a handful of brands did minor updates to their lineups, including new variants.

Realistically, that’s probably going to be pretty common for power meter companies going forward, in that the technology isn’t likely to see the massive shifts we’ve seen over the last decade, and instead focus on more minor tweaks. As for trainers, I suspect we’ll still see some more in the fall. I think many brands are trying to figure out if 2022-2023 is ‘worth the effort’ to launch a new trainer product(s).

In any case, here are the first of a few posts with leftover Eurobike stuff. Still more trainers to dive into, as well as other sports tech tidbits.

Bryton’s new Smart Trainer:

While much of the attention on Bryton at Eurobike was on their out-of-nowhere cycling radar unit, they also had a new smart trainer sitting nearby. Like the radar unit, details were hard to come by here. However, unlike the radar, I’m apparently allowed to talk about this one. Or at least, that’s what my notes say.

This direct drive trainer doesn’t appear to be any obvious re-brand of another trainer by any other companies, but, ya never know these days. A lot of trainers are being re-branded, or having a slightly tweaked case with different branding.

– Price: $899, cassette not included
– Availability: Autumn, globally (no geographic restrictions)
– Connectivity: Concurrent ANT+ & Bluetooth Smart
– Flywheel weight: 6.8kg (that’s actually reasonably beefy for this price point)
– Total weight: 22kg (weight of trainer)
– Max Resistance: 2,200w
– Claimed rocker movement: 8°
– Status LED’s: Yes, power, ANT+, and Bluetooth Smart
– Collapsible legs and handle: Yes, you can see that it can be folded in, with a handle atop
– Adjustable height: Yes, if you look below the cassette, that supporting beam can be adjusted just like a Wahoo KICKR

As noted, the Flywheel weight is 6.8kg, which is a fair bit more than the 5.4kg of the Wahoo KICKR CORE and even more than the 6.2kg of the recently announced Elite Justo. In general, the heavier the flywheel, the more realistic the inertia feel is. Though, there are some exceptions to this rule.

I didn’t have a chance to test the whole movement thing and see how it feels. But, Bryton is certainly moving the same direction as everyone else in terms of integrating subtle movement into the trainer.

Like most things, I’m sure at some point it’ll meander into the DCR Cave for a test. Bryton is probably better positioned in terms of distribution than ZCycle even TrueKinetix for wider availability, though I don’t suspect we’ll see them join the availability ranks of Tacx/Elite/Wahoo (and to a lesser extent, Saris). Those three brands have simply been around longer, and in local bike shops longer, such that they’ve established those retailer/distributor relationships over many years. Still, as always, more competition is absolutely better here.

Stages Adds Shimano R8100/R9200 Compatibility:

IMG_0956

Next up there’s Stages Cycling, which launched their Shimano Ultegra R8100 & Dura-Ace R9200 crankset compatibility, meaning, you can get a Stages unit atop the Shimano one, in case you don’t want to either pay for Shimano’s power meter (or don’t deem it accurate). Now technically speaking, Stages has already been selling the left side (single-sided) variant of this combo-dish since last fall. This adds the new right side/dual-sided option.

Semi-notable is that Stages is using a slightly different design than past Shimano right-side units, on the right side. This new design has a bit of a cradle on the backside. It’s barely noticeable from the front side, but really only easily seen when the crank is off the bike and on a stand:

The design was first rolled out on the Stages Campagnolo Super Record cranks, where you can see the ‘arms’ reaching around here:

The new units are priced as per the below nifty table:

StagesPowerMeter

It sounds like I’ll have a Stages dual-sided variant of one of the cranksets above to test here in a few weeks, and put it through the paces.

Oh, and since some will ask, just this Monday I finally got my hands on the Shimano R9200P power meter (meaning, Shimano’s power meter, not the Stages one). Testing has begun already, with a few rides completed. More in a bit.

ROTOR INpower 2022 Update:

IMG_1069

On the team of very minor updates, we’ve got a minor tweak from ROTOR, who have updated their INpower power meter, which is their single-sided power meter (2INPower is their dual-sided unit) The updated model is mostly cosmetic though, changing some outside visual aesthetics, as well as some internal components to deal with chipset shortages. However, they said that functionally it’s the same, and none of the critical components (like strain gauges) have changed.

IMG_1067

So while it might look somewhat different from the outside, it’s same-same from a consumer standpoint. However, the company did note that a new smartphone app is coming later this year that is completely revamped, both internally and visually, and promises to be (and I quote) “much more stable” than the previous app. The new app also allows recording of data, including now pushing to Strava and TrainingPeaks, as well as editing of data fields.

As the power meter wars have largely died off, at this point crankset manufacturers like ROTOR are making power meters less so to get someone to buy just their power meter, and more so to keep people on their cranksets that need a power meter. Meaning, there’s little reason a happy Shimano/SRAM user is going to jump to ROTOR just for their power meter. But inversely, the lack of a power meter would keep someone from jumping to ROTOR cranksets, if they wanted ROTOR.

Still, ROTOR has historically gone above and beyond when it comes to app metrics for their power meters, with all sorts of advanced pedaling efficiency bits. None of these metrics integrated with head units (except a very unique force-vector Polar integration that’s now discontinued), but, they were there for those that wanted them on their phones.

In any case, the new ROTOR INpower Road 2022 is set to be available from July 25, 2022 starting at a price of 499EUR.

With that – thanks for reading, and stay tuned for plenty more!

    “In general, the heavier the flywheel, the more realistic the inertia feel is.”
    I always cringe a little bit at this statement – the inertia *is* related to the mass of the flywheel, but also to its radius (to the square of the radius to be more exact), and the shape of the flywheel. So – same mass, same shape, double the radius = quadruple the inertia; same mass, same radius, going from a full disk of uniform thickness to a flywheel concentrating the mass on the periphery = almost double the inertia.

    Depending on the design, it does not take a lot for a heavier flywheel to have a lower inertia than a smaller one. You can compensate a 10% difference in weight by a 5% difference in radius to get the same inertia.

      That’s all nice and well, but if you go into all-out nitpick mode and completely skip the transmission ratio between cassette and flywheel that might differ wildly between designs, the critique seems a bit… I don’t know, allow me to keep those words to myself 😉

    • Yeah, ultimately, there’s no great way to compare many things on smart trainers. Which is why I rarely discuss flywheel weight, and instead, focus more on how it actually feels.

      But, to what I said in the article:

      “In general, the heavier the flywheel, the more realistic the inertia feel is. Though, there are some exceptions to this rule.”

      I think the second sentence covers this. 🙂

    Noticed there hasn’t been any real new updates in the power meter world in a while. 2inpower released in 2017 I think, same goes for power2max NG, favero assioma

    • Ty

      P2M NG has been updated recently with minor strain gauge refinement and a switch to a magnetic charging port instead of the micro usb. Falls in line with what Ray is saying about power meters undergoing minor tweaks instead of wholesale redesigns.

  3. Aleksandr Dorofeev

    A bunch of useless things. Slightly updated, slightly optimised. WOW! One more brand released trainer! Only one missing. (or two) Garmin 540 and 840.

    Ray,

    How do you change the battery on the right side Stages Power Meter? Do you have to take the chainrings off?

    • David

      The right is on the outside cradled next to the spider and arm. You do not need to remove the chainrings.

    • Matthew

      Thanks. I missed the picture showing the right side power meter “capsule” cradled in the outside next to the spider & arm.

    “On the team of very minor updates, …”

    Probably should be “theme” rather than “team”?

  6. ezio

    Hi DC!
    nothing related to power meter for Time pedals?
    thanks!

    No updates from Rotor for their INSpider?

    I found Shane’s review pretty damning and don’t consider it an option at the moment (INPower not an option for me as I need a shortened axle for a velomobile).
