Gearing

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

RPM

RPM = pedal turns per minute.

All published sizes28T · 11–42T · 11-speed
Lowest0.67:1 Highest2.55:1 Total range382%
Estimated speed At 90 RPM Lowest gear5.2 mph Highest gear19.8 mph

Rear tire: 27.5×3.

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.
