Gearing

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

RPM

RPM = pedal turns per minute.

All published sizes52/36T · 11–28T · 11-speed
Lowest1.29:1 Highest4.73:1 Total range368%
Estimated speed At 90 RPM Lowest gear9.1 mph Highest gear33.3 mph

Rear tire: 700C×23.

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.
