Anyone remember Chung-on-a-Stick (http://andyfroncioni.com)? The idea was to create a small wind speed and angle sensor that would allow you to compute tire and aero drag parameters with power meter data. Well, the project has turned into a commercial venture called Alphamantis Technologies. We're almost finished our first alpha product cycle, and we're looking to get some feedback about the aero field testing market.
If you're a coach or power user who's ever computed a Crr or CdA, then we'd like to hear from you. If you'd like to help us by filling out a short survey, we'd sure love you forever! :-)
