Gearing

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

RPM

RPM = pedal turns per minute.

All published sizes32T · 11–34T · 9-speed
Lowest0.94:1 Highest2.91:1 Total range309%
Estimated speed At 90 RPM Lowest gear6.8 mph Highest gear21.0 mph

Rear tire: 700C×32.

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.
