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