Gearing

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

RPM

RPM = pedal turns per minute.

All published sizes32T · 10–50T · 12-speed
Lowest0.64:1 Highest3.20:1 Total range500%
Estimated speed At 90 RPM Lowest gear4.8 mph Highest gear23.8 mph

Rear tire: 27.5×2.4.

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.
