Gearing

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

All published sizes34T · 11–50T · 12-speed
Lowest0.68:1 Highest3.09:1 Total range455%

Speed unavailable: wheel or tire size is missing or unclear.

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.
