Sterzo hacked. Go get your geek on.

Engineer extraordinaire, Keith Wakeham, has reverse engineered (aka “hacked”) the Zwift steering protocol used by the Sterzo. Published the 3D printing files and basic instructions on how to DIY one of these for ~$25 (assumptions are made). All in, this looks amazing, and were it not for Keith’s hints around future development exactly the kind of thing I would be interested in. Except that I would make two changes to the physical…

✅No boring bikes ✅Worthy cause

I’m not sure how I feel about the lines of the top tube, but you’ll get no argument from me that the Dogma F12 is a beautiful bike. If you have the dosh for a super limited, guaranteed not-boring, version, you will be able to compete for two of them on eBay starting today, with at least some portion of the proceeds supporting World Bicycle Relief (release isn’t super clear on this…

I tried Garmin, but the guys…

Yesterday my Garmin fēnix 6 was nagging me about the need for base, which of course I ignored. Hold up, not just because I didn’t want to, but because the Friday morning group ride is supposed to be slow, and laid back. So I figured that it would be easy to ride off the back in something that would approximate a base power output. That was not to be the case this…

Garmin fēnix 6 11.75 BETA fixes Indoor Training Activity

I’ve been pretty happy with the 11.10 firmware release, except for one thing. They introduced indoor trainer control, but in the process broke heart rate capture for the activity – making it impossible to determine load (doh). Fortunately that is an undocumented fix in the BETA release of 11.75, which also includes a ton of other useful features. Like “Suggested Workouts” (apparently I need some base :)). Changes made from version 11.10…

It’s supposed to work that way…

The problem with undocumented algorithms, is that we can’t really tell how they work. We can only guess based on our observations, and hope that we get it right. When limiting our sample to one, it’s pretty easy to guess the wrong way. I suspect that’s what’s happening in the case outlined below. Which to be completely fair, might be a “training issue”, a helpful feature working the way it is supposed…

Resting heart rate as an indicator of relative stress

Like a lot of people, I track my resting heart rate (RHR) as an indicator of training stress. It’s hard to know whether to CRUSH IT, take a rest day, or get in the space between otherwise. It’s a real number that provides insight into what’s going on, well before I would otherwise notice. With the worst of it over (hopefully), I thought it would be interesting to explore the impact crashing,…
