AeroStar loads your Notio JSON or Garmin FIT data

AeroStar calculates the instantaneous CdA (aero resistance) and Crr (rolling resistance).

Competitive riders demonstrate inter-lap CdA variation is CdA~0.002 or 2W. CdA resolution is sub 0.001.

Excellent accuracy demonstrated by matching analytical solutions.

What is not measured, cannot be improved.

You already know that +80% of your power goes into overcoming your aerodynamic resistance.

Welcome to AeroStar
an easy to use, super-accurate CdA tool that validates its results

Competitive cyclist riding 6 sets of 7 laps doing ABABAB testing. CdA~0.170 with Intra-lap CdA variation of 0.001 or sub 1W. CdA resolution is sub 0.001.

Validation of CdA for recreational cyclist riding Out&Back. Error between Virtual Elevation and measured elevation often sub 5cm.
