Gearing

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

RPM

RPM = pedal turns per minute.

All published sizes30T · 11–46T · 11-speed
Lowest0.65:1 Highest2.73:1 Total range418%
Estimated speed At 90 RPM Lowest gear5.5 mph Highest gear23.1 mph

Rear tire: 26×4.8.

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.
