- Data limitation

Ratio2.88:1
Estimated speed at 90 RPMGear
Uses front tire 700C×25; 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.
