Why WattGap
A CdA calculator built for real road cyclists
Most CdA tools need a velodrome or a perfect test loop. WattGap learns from the rides you already do.
The problem with field testing
Traditional aero field tests require repeated laps, calm conditions and careful protocols. Most riders never do them, so they never learn their real CdA.
Learn from normal rides
WattGap filters everyday rides for clean, steady segments and checks historical wind, so useful data comes from training you're already doing.
Grounded from day one
Because each estimate starts from your bike's published wind-tunnel figure, you get a credible number before your first upload.
