THE FUCKING POWER METER THREAD

I ordered a Calibre Biometrics device way back in July 2021. Finally got it just this week.

It's basically a portable metabolic cart. Does VO2, VCO2, RER, kcal/min, and thus from the last two can then break it down into kcal/min from fat and carbs, too. Also collects sundry other data.
Anyway, I gave it a trial run today, and despite some noise in the data that's likely related to mask leakage given my beard and the strap setup on it the numbers seemed plausible overall. Pretty cool little gadget that I'll play with more over time. It wouldn't be great for outdoor use, certainly not anything with jostling, but I can certainly use it on the Bike and the Tread.

How it works
Measuring 50 times per second, Calibre™ reads and captures oxygen intake, carbon dioxide production, respiratory flow & volume, and more. Taking these measurements and complicated formulas, the Calibre app is then able to help determine a multitude of metrics like the calorie burn rate, %carb...

I still think the mask fit/leakage was an issue, but I'm impressed with the Calibre device's openness with data. You can just click "logs" under your saved session and then you get a CSV with second by second data from sundry categories, that you can then export to wherever. I hid all but a...

More Calibre testing. This is with 100W x 20 min, 110/120 x 5 min each, then 130W until the last 10m at 100 again. So 1.8-2.1 VO2/min is expected. The raw data are noisy but when smoothed over 5 minute running intervals it doesn't look too bad. Little spike in the data were when I hyperventilated intentionally--apparently that leads to artifacts.
yes, that slow.
Favero Assioma Pro MX MTB (SPD) Power Meter In-Depth Review
Favero has finally officially announced their new SPD Favero Assioma variant, called the Favero Assioma Pro MX-2 MTB. I say ‘finally officially’, because the unit was actually non-announced back in November or so on their site. And that followed
