Gearing

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

All published sizes53/39T · 13–23T · 8-speed
Lowest1.70:1 Highest4.08:1 Total range240%

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

How it works

Ratio = chainring teeth ÷ rear sprocket teeth. A 400% range means the highest ratio is four times the lowest.

Speeds are estimates from tire size and pedal cadence. Actual speeds vary.
