Aerodynamic CdA Estimator

CdA (Coefficient of Drag × Area) represents your "aero signature." Smaller numbers mean you're more slippery in the wind.
Estimated CdA
0.3062

Lower CdA allows higher speed for the same effort.

Required Power
318Watts

Rough power estimate using rider plus bike mass at 40 km/h.

About Cycling CdA & Wattage Estimator

Create a rough level-ground CdA and wattage estimate from rider dimensions, riding position, rider mass, bike mass, and speed using fixed sea-level air density, rolling resistance, and drivetrain assumptions.
