Cycling Aero Savings Calculator

Calculate time saved by reducing aerodynamic drag (CdA) on the bike.
Quantify the benefit of aero gear, position changes, and helmets.

Average power (watts)

Current CdA (e.g. 0.35 for standard road position)

New CdA after change (e.g. 0.30 aero position)

Course distance (km)

Rider + bike weight (kg)
