Gearing

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

RPM

RPM = pedal turns per minute.

All published sizes50/34T · 11–34T · 10-speed
Lowest1.00:1 Highest4.55:1 Total range455%
Estimated speed At 90 RPM Lowest gear7.2 mph Highest gear32.5 mph

Rear tire: 700C×28.

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.
