Est CdA? Help needed
Est CdA? Help needed
I am planning to upgrade my iSport soon and want to make a note of my current calibration before the upgrade in case it gets lost. I have Aero, Fric, Crr. I know how to compute riding tilt from Fric, Crr and weight. I need help finding CdA and wind scaling. Would someone use the Est CdA screen on their unit, enter 72" height, 170 weight, on drops and download the profile and post what CdA they get? This would give me enough information to solve for wind scaling. Thanks, Mike
Re: Est CdA? Help needed
It looks to me that if Profile 2 has not had a calibration ride done, then its wind scaling equals 1. So switch to Profile 2, enter Est CdA parameters, and the resulting Aero value equals the CdA computed for those parameters. So it is easy to make up a chart relating these parameters to CdA if you want.
