Gearing

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

RPM

RPM = pedal turns per minute.

All published sizes53/39T · 12–25T · 10-speed
Lowest1.56:1 Highest4.42:1 Total range283%
Estimated speed At 90 RPM Lowest gear11.0 mph Highest gear31.1 mph

Uses front tire 700C×23; rear size isn’t listed.

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.

Your changes apply to this calculation. The archived build stays unchanged.

Your gearing setup

Use up to three front tooth counts, separated by /. For one rear sprocket, enter the same count twice.

On a tire marked 32-622, width is 32 mm and rim diameter is 622 mm. Use the rear tire on mixed-wheel bikes. Leave tire fields empty to compare ratios only.

Speeds are estimates. These calculations do not establish component compatibility or available tire clearance.
