Gearing

Lower gears help on climbs. Higher gears suit higher speeds.

RPM

RPM = pedal turns per minute.

All published sizes30T · 11–51T · 12-speed
Lowest0.59:1 Highest2.73:1 Total range464%
Estimated speed At 90 RPM Lowest gear4.7 mph Highest gear21.7 mph

Rear tire: 29×2.6.

How it works

Ratio = chainring teeth ÷ rear sprocket teeth. A 400% range means the highest ratio is four times the lowest.

Speeds are estimates from tire size and pedal cadence. Actual speeds vary.
