Gearing

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

RPM

RPM = pedal turns per minute.

S630T · 10–52T · 12-speed
Lowest0.58:1 Highest3.00:1 Total range520%
Estimated speed At 90 RPM Lowest gear4.5 mph Highest gear23.4 mph

Rear tire: 29×2.3.

Gearing not shown: S1, S2, S3, S4, S5.

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.
