Gearing

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

RPM

RPM = pedal turns per minute.

All published sizes42T · 11–40T · 10-speed
Lowest1.05:1 Highest3.82:1 Total range364%
Estimated speed At 90 RPM Lowest gear7.8 mph Highest gear28.2 mph

Rear tire: 650B×2.3″.

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.
