Gearing

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

RPM

RPM = pedal turns per minute.

All published sizes32T · 10–51T · 12-speed
Lowest0.63:1 Highest3.20:1 Total range510%
Estimated speed At 90 RPM Lowest gear4.9 mph Highest gear24.9 mph

Rear tire: 29×2.3.

How it works

Ratio = front teeth ÷ rear teeth. Hub gears also include the hub’s internal ratio. A 400% range means the highest ratio is four times the lowest.

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