Gearing

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

RPM

RPM = pedal turns per minute.

All published sizes36/26T · 11–40T · 11-speed
Lowest0.65:1 Highest3.27:1 Total range503%
Estimated speed At 90 RPM Lowest gear5.0 mph Highest gear25.1 mph

Rear tire: 29×2.1.

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.
