Gearing

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

All published sizes30T · 11–46T · 11-speed
Lowest0.65:1 Highest2.73:1 Total range418%

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.
