Gearing

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

RPM

RPM = pedal turns per minute.

MD · 29″, LG · 29″, XL · 29″32T · 10–51T
Lowest0.63:1 Highest3.20:1 Total range510%
Estimated speed At 90 RPM Lowest gear4.9 mph Highest gear25.1 mph

Rear tire: 2.4″ + 29-inch.

SM · 27.5″, MD · 27.5″34T · 10–51T
Lowest0.67:1 Highest3.40:1 Total range510%
Estimated speed At 90 RPM Lowest gear5.0 mph Highest gear25.3 mph

Rear tire: 2.4″ + 27.5-inch.

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
Gears

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

Rear tire

Apply the marking on your rear tire or edit its dimensions below. Older or fractional inch sizes need the ISO marking (e.g. 37-590).

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

Gear, dimension and cadence changes update results automatically.

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