AeroEdge turns aerometer and power-meter files into a CdA you can defend: three independent physics models, transparent calibration, and your gains translated into time on the courses you race.
Your power data implies an elevation profile. If the profile your laps draw is flat where the road is flat, your CdA and Crr are right. Drift shows up as a slope, visible at a glance, not buried in an average.
Aerodynamic drag, rolling resistance, kinetic and potential energy, drivetrain loss: the validated power model solved lap by lap for a direct CdA estimate that cross-checks the trace.
With an aerometer on board, apparent airspeed is data. Crosswinds and gusts stop being noise, and AeroEdge calibrates your sensor from your own validation runs, with every coefficient on screen.
This is a real virtual-elevation shape: each hump is one velodrome lap. As the modelled CdA converges on the true value, the trace flattens. When it's flat, the number is earned: that's the whole method, visible.
Every assumption visible. No false precision.
An out-and-back on a quiet road, or laps of a velodrome. Consistency matters more than perfection.
Ride the segment in the setup you want to measure (out and back), so direction effects cancel.
Helmet, hands, tyre pressure, skinsuit. One variable per comparison, then ride the pair again.
Group runs into a session, name each setup, save laps. Originals are stored: when your calibration improves next month, re-analyse every old run against it.
A CdA delta means nothing until it's seconds. Upload a GPX, set CP and W′, and simulate or optimise pacing with your measured numbers, forecast wind included, segment by segment.
