Gearing

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

RPM

RPM = pedal turns per minute.

All published sizes48/35T · 10–33T · 12-speed
Lowest1.06:1 Highest4.80:1 Total range453%
Estimated speed At 90 RPM Lowest gear7.5 mph Highest gear34.1 mph

Rear tire: 700C×26.

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.
