Week in Review: April 5th, 2021


The Week in Review is a collection of both all the goodness I’ve written during the past week around the internet, as well as a small pile of links I found interesting – generally endurance sports related. I’ve often wondered what to do with all of the coolness that people write, and while I share a lot of it on Twitter and Facebook, this is a better forum for sending it on to y’all. Most times these different streams don’t overlap, so be on the lookout at all these places for good stuff!

So with that, let’s get into the action!

Sports Tech Deals:

There’s a handful of sports tech deals out there right now:

ProductSale PriceAmazonOther siteSale Notes
All Amazon Kindles: 33-45% offVariesBoth myself and The Girl have Kindles for reading. In her case, she uses hers daily. In my case, it ends to be more vacation/weekends. We both recently upgraded are crazy-old ones to the newer Paperwhite editions. We don't need much fancy.
Amazon Echo Dot - 53% off$19I use these around the studio and home - and for $18, it's kinda incredible what kind of technology they can pack into that price.
Amazon Halo Wearable Band - 30% off$69
Apple AirPods Pro - $60 off!
Apple AirPods with Wireless Charging Case - $50 Off!$149⚡ I use AirPods primarily when I'm travelling just to listen in airports, planes, etc... I don't tend to use these for workouts due to them falling out. Personally, I just use the basic model.
Apple Airpods (2nd Gen) - $30-$50 off
$99-119I use AirPods primarily when I'm traveling just to listen in airports, planes, etc... I don't tend to use these for workouts due to them falling out. Note: Price fluctuating between $99-$119 throughout day.
Apple TV 4K (2021 Edition) for Zwift - $29 off$169I use this for almost all my Zwifting. This is the first major deal we've seen on something barely a month old. Also, the 32GB model is on sale too, from the same link.
Apple Watch Series 6 - (40mm) - $120 Off
$399/$499 (cellular)
$279⚡⚡ The strongest deal yet on the Apple Watch Series 6! Note, this price is fluctuating constantly throughout the day, so keep checking back if it's not showing the lowest price.
Apple iPad - Latest Model 8th Gen (32GB) - 10% off$299I use my iPad primarily for TrainerRoad as well as Zwift when not with a larger display. I also occasionally use it for other apps, namely The SufferFest - but I pretty much test every smart trainer app on it. (US AMAZON DEAL ONLY).
Beats PowerBeats Pro Wireless Sport Headphones - $30 off
$169⚡ These are my daily driver headphones that I use for all my trainer rides, and anything else sport related. While they're not perfect (namely the charging case), it's what I keep going back to every day because of the seamless Apple ecosystem integration (iPad/Apple TV/iOS/Mac).
DJI Mavic Mini Fly More Combo Kit - 24% off$399
Fitbit ACE 2 Activity Tracker for Kids - 57% Off$29Umm, this is an incredible. So incredible that I've almost gotta wonder if this product line is going to be kept around. Fitbit never discounts this much. But hey, they also never drop support on things - so it frankly doesn't matter much if there's not an ACE 3 or something.
Fitbit Charge 4 - $50 off!
$99Currently the best deal we've seen to date, matching only the Black Friday deal last fall.
Fitbit Inspire 2 - 40% off
Fitbit Sense - 40% off
$199This is the lowest price to date for the Fitbit Sense (by far), and makes it a deal you should definitely consider versus the Fitbit Versa 3 for the same price (no, really, there's no reason to get the Versa 3 at the same price).
Garmin Edge 1030 Plus - $110 off
$490⚡ I don't think this particular discount will last long. It seems a bit quirky the way it's worded on Amazon's page. Note that the Edge 1030 Plus was on sale for $100 off till last week, so in some ways this is just a continuation of that for a tiny bit longer/more.
Garmin Edge 130 Plus - 30% off!
$139⚡ This is the lowest we've seen the Edge 130 Plus on sale. The 'Plus' variant is notable compared to the regular unit for having ClimbPro on it, plus a handful of other tweaks. $139 is a great deal for it.
Garmin Fenix 6 Sapphire (Pro) - $300 off$499⚡⚡⚡ This is probably the best deal of the day for this Fenix 6 Pro Sapphire edition, which includes the maps/music/Wifi, and is discounted far more than the rest of the lineup.
Garmin Fenix 6 Series - $100 all models
$100 off⚡ This deal is back! A variant of the $100-$150 off Fenix range deal shows up each May/June ahead of Fathers day and past Amazon Prime Day, and this is no different. This also includes the newer Fenix 6/6S Solar units from this past summer.
Garmin Forerunner 245 - $50 off
$249Both the Forerunner 245 is on sale for $50 off. While not a huge sale, it's actually the lowest we've seen either product priced to date.
Garmin Forerunner 245 Music - $60 off$289Both the Forerunner 245 Music is sale for $60 off. While not a huge sale, it's actually the lowest we've seen either product priced to date. The FR245 Music supports Spotify, Amazon Music, and other streaming platforms.
Garmin Forerunner 45/45S - $20 off
$139This is a good deal, though, keep in mind the Forerunner 55 just came out. So the 'normal' list price of $199 for the FR45 isn't really true anymore (that's the new FR55 list price). Thus this is roughly $20 off. In any case, it's a great running watch.
Garmin Forerunner 745 - $25 off
$475The FR745 multisport GPS watch has music support (including Spotify), and is otherwise a full triathlon watch. This is only the second time we've seen it on sale since release. So $25 off is better than nothing off.
Garmin Forerunner 945 - $83 off
$515Not a bad deal, the price seems to fluctuate between $80-$85 off (official Garmin sale price currently).
Garmin Instinct Esports Edition - 40% off$179This is actually the first time we've seen a deal on this quirky little variant of Garmin Instinct, meant to pair up with its own special app for transmitting data to streamers.
Garmin Instinct Solar - $150 off
$249⚡ By far the best deal we've seen on the Instinct Solar edition, which came out last summer.
Garmin Instinct Tactical- $120 Off$179This is the lowest this watch has been ($120 off, and down to $197). Note that this is the non-Solar version, so do keep that in mind.
Garmin Varia RVR315 Radar - 23% off$104This is Garmin's latest gen Varia radar, without the light portion. This is also by far the best deal we've seen on it.
Garmin Varia Radar (RTL515) - $30 off$169This seems to go on sale about once per year, and this be that time. If you're looking to pick one up, I wouldn't expect any further deals till probably Black Friday timeframe.
Garmin Venu GPS Smartwatch - $130 off!
$219⚡ This is about the lowest we've seen yet for the Garmin Venu GPS (by far), which includes an AMOLED display as well as music (even Spotify offline). Solid deal. Note, the Venu 2 did come out last month.
Garmin Venu SQ Music - $60 off
$199/$249 with Music
$189This is a good deal on the music edition, making it the lowest price we've seen to date.
Garmin Vivoactive 4/4S - $100-150 off
$189⚡ This is Garmin's current offering to compete with the Apple Watch series (alongside the Garmin Venu/Venu 2), and is currently the lowest price we've seen to date, even better than Black Friday last year. Historically Garmin refreshes this lineup the last week of August this year, but who knows what the future holds.
Garmin Vivofit Jr. 3 - 38% off$49This deal easily beats Black Friday last year, making it the lowest we've seen on the Vivofit Jr 3 series.
GoPro Hero 9 Black - $50 off$399This is the camera I use for all my daily shooting during sports. Actually, I've bought a few of them. Note that if you're a GoPro Plus Subscriber, then it's a bit cheaper at $349 from GoPro directly, but otherwise, it's $449.
Google Nest Mesh WiFi Router - 30% two-pack$205These are the WiFi mesh access points I use both at home and the DCR Cave. Love them - I don't need to dork with them, they just work.
Insta360 One R Action Cam - 5% off$469The entire lineup of Insta360 One R action cams are 15% off, including the 1" and 360 variants. Overall it's a good cam with good picture clarity (I've mainly used the 1" 5.3K variant), but I find the software really lets it down.
Jackery Portable Power Station - $100 off$199This is something I use frequently when shooting out and about and I need to re-charge a crapton of drone batteries, action cameras, or just cameras and such. I also use it on trips to Eurobike and elsewhere to keep equipment charged. Technically you can even hook a solar panel up to it. Heck, I've even powered a KICKR trainer ride from it!
Lacie 2TB & 4TB Ruggedized USB Drives - 41% off$91These are the drives I primarily use for large piles of storage with my laptop and daily use before offloading to a file server. I also sometimes edit videos off these too (though, for multiple 4K streams in video it can be a tiny bit slower than SSD drives). But still, definitely recommend these.
Nest Cam Indoors - 23% off$99We have more Nest cam's than I can count. No really, we have half a dozen at the DCR Cave alone, plus more at home. We love them. Nest Cam's really only go on sale about 1-2x per year.
Nest Cam Outdoors - $50 off$149We use one of these and so far after I think just about three years, it's working great for us. Love it, and works better than trying to stick a regular Nest Cam out the window (since it'll reflect both during daytime and at night with the IR sensor).
Nurvv Running Insoles - 40% off
$179This is a pretty new product, just launched this past fall that sits inside your shoe and even has GPS built into the pod sidewalls. However, just last week (mid-June) it got an update that now includes a new footstrike coach/target system.
Polar Ignite GPS - $40 off
$159This is a good deal for a good unit. As with the Polar Vantage M deal, it's no longer the most recent version of this watch, but it's still got a ton of features packed into it.
Polar Vantage M - $50 off
$223This isn't the latest model anymore, but it's still a really solid multisport watch.
Samsung Galaxy Buds Plus Wireless Earbuds - 43% off$84
Samsung Galaxy Watch 3 - 35% off$279This is almost the lowest price I've seen on the Samsung Galaxy Watch 3
Samsung Galaxy Watch Active 2 - 36% off$159
SanDisk 1-2TB Extreme PRO Portable External SSD - 36-45% off$169This is one of the two the high speed drives I use to store the footage I'm actively video editing, so that I can edit it on both my iMac at the office, and then my MacBook when travelling or at home.
SanDisk 256GB Extreme PRO SD Cards - 52% off$47I use the SanDisk Extreme Pro SD Cards exclusively for all my video/photo shooting on my Panasonic GH5 and Nikon cameras (video and stills), including up to 6K recording with the GH5. I've mostly used 128's, but more and more lately I'm filling up cards faster with higher bitrates, so this sale is gonna have me pickup a bunch of the 256GB ones instead. The 128GB/512GB/1TB ones are also on sale too viathe same link.
SanDisk 256GB MicroSD Card - 40% off!$28I use this card in both 128GB and 256GB variety, and it's perfect for all my drones and action cams, easily recording 4K/60 and 5K/30, as well as 5.7K without trouble. I often pickup these cards when on sale like this, so I have them for later in the year when not on sale.
Suunto 7 Wear OS Watch - $128 off
$270This is the lowest price we've ever seen the Suunto 7 Wear OS powered watch at. Plus, it continues to get new features too!
Suunto 9 Baro Series - $100 off
$599 (non-baro is $499)
$499This isn't quite as good a deal as a few weeks ago when it was 42% off (basically $200 off), but it's still a deal nonetheless.
Synology 4 bay NAS DiskStation DS920+ (Diskless) - $110 off$439⚡ I use Synology NAS units for all my file storage at the DCR Cave. This unit is a slightly smaller variant of what I use (DS1817), but mainly just with less storage space. The DS920+ linked here is a solid deal at $110 off, though, keep in mind if just using for simple storage, the DS418 is cheaper (but doesn't support expansion units). Also, remember you'll need to add disks. I currently find 8TB units are the sweet spot on price vs capacity.

YouTube Videos This Past Week:

Here’s what hit the tubes over on the You of Tube, definitely don’t forget to subscribe there to get notified of videos the second they hit!

Stuff I Found Interesting Around The Interwebs:

Here’s a not-so-small smattering of all the random things that I stumbled on while doing my civic duty to find the end of the Internet. Also, there’s a few things this week that were actually from a week or two ago – I’m just catching up on this list:

1) A deeper look at the Wahoo Speedplay Power Pedals (engineering perspective): For those that know Keith, he’s one of the most public power meter developers in the industry, and also behind many sports tech gadgets within the cycling world from a number of companies. Here’s his most recent look at the FCC filings from Wahoo, on their recently announced Wahoo Speedplay power meter:

2) ZwiftHub Closing Down: Congrats to Toby (the person behind it) on his new job at Wahoo. Unfortunately, it means at the end of the month, ZwiftHub is no more. Perhaps Zwift will consider acquiring it for a fair rate.


I do think this once again though shows how big a boon it would be for Zwift to actually have a proper/supported API, akin to what Strava has, for people to Create Cool Shit. It’s these sorts of projects that should eventually be built into Zwift (or acquired). But as Strava and their 20,000+ apps shows, there’s an incredible potential for 3rd party apps to fill in the gaps and increase the community around Zwift.

3) Peloton closes Precor acquisition – shifts focus to Commercial usage: In the grand scheme of sports tech deals, this is one of the bigger ones in recent years, as it will dramatically increase production capability for Peloton. However, when it was announced last December, it didn’t mention increasing focus on the commercial side of Peloton – it just mentioned getting gear to ‘members sooner. However, the new announcement specifically calls out using Precor to focus on the commercial aspect of Peloton (e.g. hotels/apartments/etc…), which by and large Peloton has treated as the red-headed stepchild over the years. Yet, it’s also a great place to introduce people to the Peloton brand with zero marketing cost.

4) A look at the 2021 Chip Shortage: This is a good dive into the semiconductor chip shortage and how it’s impacting the industry (including sports tech). While sometimes this will be obvious to you as a consumer, most times it won’t be: It’ll just mean delayed product launches behind the scenes, or perhaps limited availability without a reason. This is mostly the reason.

5) Casio launches new WearOS watch: Though, perhaps unsurprisingly, without solar capabilities. Given WearOS has the well-earned reputation of being the Cookie Monster of battery burn, the trivial amount of power that solar delivers in most watches probably wouldn’t last more than a song on WearOS. Still, good to see more options. Hopefully we’ll see Casio find a way to refine what they have sports-wise today, which in my testing of their GBD-H1000 (solar, with FirstBeat Analytics) seemed like a promising vision, but fell pretty far short in reality. For example, there was only one sport mode (running/hiking), which meant if you wanted to use it for a ride – it screwed up all your data.

5) Garmin engineer discussing dual-band GPS implementations: Nothing crazy deep, but some tidbits there for those that are interested.

6) Want a cargo bike emoji? One emoji developer is looking at submitting a cargo bike emoji for consideration, however, he is trying to nail down the design. Give a quick tap on this Twitter vote to help.

7) Equipping cyclists to identify bad bike intersections: This project equipped 700 cyclists with little beepers that they’d tap when they stumbled upon poor/clumsy bike situations. During the trial some 36,000 situations in Amsterdam were identified, giving city planners areas to consider upgrades for. Looking at the map, I’d definitely agree with most of the larger dots.

Sports Tech Device Firmware Updates This Week:

Each week I quickly highlight some of the new firmware, app, software, and website service updates that I see go out. If you’re a sports technology company and release an update – shoot me a quick note (just one-liners are perfect, or Tweet it at me is even better) and I’ll make mention of it here. If I don’t know about it, I won’t be able to post about it. Sound good?  Oh – and if you want to get a head start on things, this page is a great resource for watching Garmin, Wahoo, Polar, and a few other firmware updates.

Garmin Swim 2 Firmware Update: Bug fixes

Garmin Fenix 5 & 5 Plus Series BETA Firmware Update: Bug fixes (including fixing a Physio True-up updating issue)

Suunto 5 Firmware Update: Adds turn by turn with Komoot, supports POI interest/navigation

Suunto 9 Firmware Update: Adds Tour battery mode, turn by turn with Komoot, POI, and Suunto Plus Red Bull app.

(Kinda a quiet week for firmware updates)

With that – thanks for reading!

    Did you notice that the SRAM AXS Power meter has dropped to 450 USD (from 600?), what a great deal now!

  2. Joe

    Damn. I haven’t used Zwift in a bit as it’s gotten nicer out, so this is the first I’m seeing about ZwiftHub. I load up ZwiftHub before literally every ride to help determine a route. What a huge loss.

  3. Andrew

    Not a single post on Instagram last month? Is the extra one in Feb the reason or are you going for two posts this month? I think the KFC cargo bike would’ve qualified?

    • Yeah, I’ve gotta be careful to not over-deliver here. Given the two Instagram posts in February, March would indeed seem to warrant a skip to keep things on the right progression. 🙂

      (Actually, I remembered at 12:05AM on Apr 1st, and then was like…well…crap me.)

  4. Keren

    Hey Ray,

    Will also be sad to see ZwiftHub go. But it seems ZwiftHacks has already come up with a solution? But Zwift should have something set up already as a matter of course. Good luck to Toby at Wahoo, he will do great there.

    To change the subject but to stay on Zwift. Not sure if you have seen this recent news, but Zwift finally did what they said they would do a year or two ago, and stopped supporting the Milestone Pod app from 1 February. You can still use it to run on Zwift but there is no way to see your data and stats anymore. Or even check the battery level. Lot’s of unhappy Milestone Pod users here:
    link to forums.zwift.com

    I also use a Milestone for my Zwift runs and they shut the app down without any warning. They should have said something at least that it was about to lose support.

    Maybe you can dig a little deeper about this? Seems Zwift just doesn’t care about the pod that they bought.


    • Bummer, that sucks. Though, somewhat inevitable I suspect. Largely, as I bet that Zwift might not even have on staff any longer the couple people that were behind Milestone. :-/

  5. Onno

    I assume the purpose of the “Trending Now on DC Rainmaker” overlay isn’t to scare off visitors, but in its current form it’s doing just that. While it could be somewhat interesting in theory (but not too much, since I’m obviously already reading the site), having it pop up on every single page and obscuring the real content makes it more annoying than any 3rd party ad I’ve seen here.

    • Yeah, it’s something that’s being tested by the ad company I have the last week. It’s not quite where we want it yet. It seems fine on desktop, but a bit over the top for mobile. Appreciate the feedback – trying to find the right balance is always tricky. But I’ll keep trying!

  6. usr

    Oh, i love FCC internals. So (unsurprisingly, given the first external pictures) same gauge placing as Assioma, but definitely a new design regarding board and battery. Those Powerzero things will be light! Battery cells appear to be similar size 60mAh, but Wahoo using only two per pedal instead of three. And it looks like Wahoo is going for a conventionally sealed cavity instead of playing it safe and flooding the entire pod with resin. On top of that, not only is the board more integrated (less distinct components in addition to the nrf52 they all use), they also skip the magnet for the charging adapter, opting for simple mechanical clipping instead.

  7. RIP ZwiftHub

    ZwiftHub will be sorely missed. It’s worth noting that the developer noted his dream was to work in this space, yet ended up being hired by Wahoo, not Zwift. How dumb can Zwift be? They should’ve hired the guy and had him start by making ZwiftHub’s functionality part of the Companion App.

    Also interesting around the interwebs:

    ‘Beseffen jullie wel hoe perféct Amsterdam is?’ in de NRC van Stan Putman, dd. 8 april 2021.

    (..) Toch is het heel speciaal wat zich achter uw venster afspeelt, meent de Canadese Amsterdammer Jason Slaughter (44). Het is zelfs zo bijzonder, dat hij ervoor naar Nederland is verhuisd, na omzwervingen langs de VS, het Verenigd Koninkrijk, Taiwan en België. Op zijn YouTube-kanaal Not Just Bikes (link to youtube.com) legt Slaughter uit dat het aangename leven in Nederland alles te maken heeft met de manier waarop ons land is ontworpen. Hij plaatst er filmpjes over Nederlandse geneugten als slimme stoplichten, autoluwe straten en gescheiden fietspaden. Met de video’s bereikt Slaughter een publiek van honderdduizenden mensen. Filmen doet hij met een handzame digitale camera, of, als hij op de fiets zit, met een schokbestendige Go Pro-camera die hij op zijn borst bevestigt.(..)

    Hi, do you think or know if there is a Coros Apex 2 arrivng as I am thinking of buying the Apex, but would wait if an Apex 2 is arriving this year…. should I wait or Buy? Tricky…

    Looking forward to your newsletter!

    • Tom

      My weekly look for new sport tech updates, reminds me to come to your ‘week in review’, and then i find myself looking around.
      Shame it’s not updated as much, it’s always a good read. Don’t simply want to bookmark the other page, as I might never come back here 😉
