Gearing

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

RPM

RPM = pedal turns per minute.

All published sizes44/32/22T · 11–34T · 9-speed
Lowest0.65:1 Highest4.00:1 Total range618%
Estimated speed At 90 RPM Lowest gear5.0 mph Highest gear30.7 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.
