Aerometers and Marginal Gains
Aerometers have made it to market and promise some real time measurement of marginal gains. Take a listen as our special guest Michael Liberzon, host of the Endurance Innovation Podcast talk about their journey to bring this game changing technology to market.

Nice podcast as always. Regarding the topic of the temperature depency of the rolling resistance: on the one hand, as mentioned, the pressure can vary but on the other hand the loss factor of polymers can also depend on temperature. I don’t know if the changes are relevant or not but a second argument that the rolling resistance could be temperature dependent.
Very nice, good questions from Hottie, good responses from Michael.
The promise of the new generation of aero sensors is that they would make drag testing easy. I’m not sure that’s achievable with the current devices: I think they can widen the range of conditions under which one can test, which makes finding an appropriate test venue easier, but they’re not a substitute for good protocols and careful execution. They let you test more frequently, but not necessarily more accurately or precisely. When I teach I often emphasize fundamentals so sometimes I think it can be good to do a few “plain” VE tests on laps to get to understand problems, limitations, techniques, and protocols. As Michael noted, slope and elevation measurements are critical, and laps of the same course mostly side-step that issue.
