Published drivetrain ratios

Gearing

Chainring ÷ rear sprocket

Lower ratios provide more mechanical advantage for climbing. Higher ratios turn the rear wheel farther with each crank revolution.

Published build50/34T · 11–32T · 10-speed
Lowest1.06:1 Highest4.55:1 Total range428%

The bar uses the same mechanical-ratio calculation as Compare. Wheel-dependent speed appears only when the record includes an exact ISO/ETRTO rear tire size; no tire size is assumed.
