Week in Review – December 4th, 2017


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!

DCRainmaker.com posts in the past week:

Here’s all the goodness that ended up on the main page of DCRainmaker.com this past week:

Sports Tech Deals of Note:

Despite what you might think – the sports tech deals are cruisin’ on!  In fact, especially for Europe, which has seen the lowest prices ever for many items, much of which is still matching Black Friday sales.  All of these are detailed on the massive deals post that I still keep updating.

Still, here’s the rundown of major deals still cookin’:

Fitbit Alta$129$30 off!Dec 10 2017Dec 24 2017LinkLinkN/A
Fitbit Alta HR$149$20 off!Dec 10 2017Dec 24 2017LinkLinkN/A
Fitbit Blaze$199$50 off!Dec 10 2017Dec 24 2017LinkLinkN/A⚡Not too shabby a deal on this unit. It requires your phone for GPS, but otherwise it's a good option for a more full featured Fitbit.
Fitbit Charge 2$149$20 offDec 10 2017Dec 24 2017LinkLinkN/A
Fitbit Ionic$299$30 off!Dec 10 2017Dec 24 2017LinkLinkN/A⚡About the best deal we'll likely see for a while on Ionic (it was down a bit more for Black Friday, but that's a rarity).
Garmin Fenix5 (5/5S/5X)$599$100 offNov 13 2017Dec 24 2017LinkLink⚡ Definitely the best deal you're going to see this year on this.
Garmin Forerunner 235$329$30 offDec 10 2017Dec 24 2017LinkLinkN/A

Garmin Vivofit Jr$79$49Nov 22 2017Dec 23 2017LinkLinkThe lowest we've seen this unit. Was super popular last year (the most popular item ordered via DCR actually).
Garmin Vivofit Jr. 2$99$69Nov 22 2017Dec 23 2017LinkLink⚡ This just came out 5 weeks ago, and so this is a solid deal. Note: This price was dropped $10 further on Dec 5th.
Garmin Vivosmart 3$139$99Nov 22 2017Dec 23 2017LinkLink⚡ Note this just came out earlier this year, if looking for an activity tracker as opposed to a GPS watch, this is a great deal.
Garmin Vivosport$199$149Nov 22 2017Dec 23 2017LinkLinkThis just came out back in September, so a pretty good deal.
TomTom Adventurer (Music + OHR + GPS)-$50 offDec 10 2017Dec 31 2017LinkLinkN/ADown to $299, includes music, optical HR, and GPS.Note: TomTom wearables division is being shut down however.

Garmin Edge 520 $299$219Nov 28 2017Dec 20 2017LinkN/AN/A⚡ ⚡ Note: This has an unknown end date. Could be in 2 minutes, or in 2 weeks. No idea, it's an Amazon specific deal.
PowerPod$299Dec 10 2017Dec 19 2017LinkLinkN/A$249 for the ANT+ version, $279 for the BLE version, and $299 for the dual ANT+/BLE version

DJI Mavic Pro$999$200 off!!!Nov 23 2017Dec 20 2017LinkN/AN/A⚡ I love my Mavic and use it anytime I'm not using my DJI Spark. Simple line in the sand is quick vacations/cycling I'll take DJI Spark with me. Whereas for really cool destinations with lots of flying I'll take DJI Mavic Pro.
Garmin VIRB 360$799$100 offDec 10 2017Dec 16 2017LinkLinkN/A⚡This is the first US sale we've seen on this unit, and likely done to edge you to purchase it over the GoPro Fusion or Rylo cameras. While Rylo is in a different (lesser) category, Fusion is similar, but not yet as mature as the VIRB 360.
GoPro Hero5 Black + 32GB SD + $40 store credit$399$100 off!Dec 10 2017Dec 31 2018LinkLinkN/A⚡ This is technically a permanent price drop effective Dec 10th, but now the GoPro Hero 5 Black is $299! I'm listing it here for now since it's a good deal if you don't care about the new Hero6 features. Also, this edition on Clever Training includes a 32GB SD card and a $40 store credit (great for picking up a few extra batteries).
GoPro Hero5 Session$299$100 off!Dec 10 2017Dec 31 2018LinkLinkN/A⚡⚡⚡ This is technically a permanent price drop effective Dec 10th, but now the GoPro Hero 5 Session is $199! I'm listing it here for now since it's a good deal, especially if you want a small camera that has 4K capabilities and is totally waterproof.
GoPro Hero6 Black$499$50 off + 32GB CardDec 10 2017Dec 16 2017LinkLinkN/A⚡ Awesome deal ! Also includes a 32GB micro-SD card tossed in. Amaze-ball deal for a brand new unit! CLEVER TRAINING ONLY
GoPro Karma Drone Hero5 & Hero6 Bundles$200 offDec 10 2017Dec 24 2017LinkLinkN/AWhile I don't generally recommend the GoPro Karma drone...if you really want it, it's on sale for about 20% off. Instant price reduction for the Karma Hero5 and Hero6 bundles.

YouTube Videos I Made This 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 that 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.

1) The most incredible bike share photo: This photo shows what happens when you fill an entire football field with discarded bike share bikes…and stack it as high as some buildings.  Unbelievable, you really need to see this photo.

2) Jumping into an airplane with a wingsuit: Undoubtedly, many of you have seen this by now.  But if not, enjoy.  And if you have already, enjoy it again. It’s worth it, as you know.

3) Getting the GoPro Shot (further details): Last week I shared a GoPro video on the behind the scenes of just one brief sequence in the launch video.  This post however details that out even further in a more textual manner.

4) SoulCycle now offered as benefit on a points credit card: For those in Europe, the whole credit card points thing is illogical.  But for those in the US/Canada, you know it’s all about the points card.  This card apparently offers free days at SoulCycle. I thought it was interesting (I’ve never done SoulCylce however).

5) Fitbit selected for long-term national health study: Regardless of which vendor is selected, it’s good to see some long-term studies being done with vast numbers of people.  Let’s just hope that there’s at least a few people that understand technology helping with this study, so that we don’t end up with all the flawed ones we see recently on wearables.

6) GlovePay, it’s a thing: Forget Garmin Pay and Fitbit Pay, for the upcoming winter Olympics, you’ll be able to pay by rubbing your gloves against the payment terminal.

7) FDA approves first EKG reader for Apple Watch: This is an interesting one, but one you shouldn’t be misled by the main headlines about it.  This is NOT the FDA approving the Apple Watch as an EKG reader.  Instead, it’s the FDA approving an accessory for the Apple Watch by a 3rd party company as an EKG reader.  The cool part here though is that it’s doing it via an Apple Watch band/strap that you then place your finger on.  I’ve gotta believe the company will look to make straps for other devices like Fitbit and Garmin, since it’d be easy for them to leverage app platforms on both companies devices.

8) Study looking at accuracy of the CycleOps Hammer trainer: Not too shabby.  Though personally I would have liked to have seen wattages above 500w, since that’s pretty low by most testing standards.  (via Tim)

Sports Technology Software/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 firmware updates.

Garmin Edge 520 and 820 Firmware Updates: Adds latest Connect IQ support, tweaks some indoor trainer stuff, other fixes. (both units identical here on update)

Garmin Edge 1000 Firmware Update: Adds latest Connect IQ support.

Garmin Edge 1030 Firmware Update: Adds latest Connect IQ support, boatload of other tweaks and some new features.

Garmin Fenix Chronos BETA firmware update: Bunch of fixes/tweaks.

Garmin Forerunner 735XT Firmware Update: Adds latest Connect IQ support, some Varia Vision tweaks.

Garmin VIRB 360 Firmware Update: Apparently resolves random things that were too random to list.

Wahoo ELEMNT/ELEMNT BOLT Firmware Update: Mostly bug fixes, but a smattering of new features including zero averaging calculations.  GPLama also did a more detailed piece on it here.

Zwift update: You can now control the camera with far more granularity, allowing you to rotate it around you like drone shots.  Also a pile of other new features and stuff, but the camera one stood out to me as nifty.

With that, thanks for reading!

    $349 for the PowerTap C1 chainring power meter is an amazing deal. I just purchased – upgrading from left-only Stages. Thanks Ray!

    I just recently found out about the Apple Heart Study. I’ve installed the app on phone and watch and signed up but nothing has happened yet. I don’t know yet whether they’re going to take data from anyone who signs up or only a selected few. Looks like it’s being paid for by Apple and run by Stanford.

    What a shame that the Chinese government is just creating a giant scrap pile of bikes, rather than stuffing them in to containers and sending them somewhere that could really benefit from them through something like link to worldbicyclerelief.org. I’m sure that the vast majority of those bikes could be repaired by cannibalising parts from other bikes, at least before the were heaped up so high, which has likely bent anything more than a few feet deep beyond rescuing.

    • Indeed, that was both my and The Girl’s first thought as well. Just thinking that WBR could likely whack the bike locks off of these and call it macaroni.

      Of course, it’s far more complex that that – but certainly some org must be able to use these in rural locales.

      Here in Hong Kong I first thought that bike sharing was a good thing until it became obvious that many users are just too irresponsible and just leave the bike where they need to get off. That is in the middle of the walking/running path, in front of stairs or anywhere else they get in the way of other cyclists and pedestrians. The bike share companies are not much better, pushing out their bikes in public bike parking to the extent where there is no spot free for people to park their private bikes. Setting aside the fact that its a waste to just discard them, I would not mind if I saw a pile like the one of the pic here in Hong Kong.
      I do remember a similar but smaller pile on a pic form Beijing, It was outside a hospital and it was bikes left by incoming patients that had to be piled up so they didn’t block access to the hospital.

    The Hammer study summery says they are comparing to a “scientific SRM system” while the full text says its Powertap P1 pedals. Gee, I wonder who funded this…..

    “The last 45s of each measurement was analyzed.”
    Doesn’t a persons power output get steadier towards the end of a 3 min interval so easier to measure? Seems like steady state was accurate but the sprint test wasn’t so good based on figure 1.B

    For those who want the full text: link to fredericgrappe.com

    • Nice find, I couldn’t find it quickly. That is odd.

      What’s funny is that in looking at the authors of the study with their affiliations listed in the full text, I know from some other things just being local they work very closely with PowerTap/CycleOps on other projects. Didn’t recognize the author names, but definitely the orgs. Good call…

    The comment on the dual sided WatTeam power meter says:
    It’s £300 for a dual one or £204 for single (as you say in the next line down).
    And the DCR discount applies too, so it’s even cheaper! :)

  6. Hello Ray

    Tourism Flanders has created a website ‘Cycling in Flanders’ to promote its cobblestones classics to foreign cycling tourists: cool!
    Info on http://www.cyclinginflanders.cc

    Kind regards

    I think you have discussed this before but I can’t find it — do we know how long for tomtom have committed to supporting their web platform?
