Bike Gear Ratio Calculator
Bike Gear Ratio Calculator
This calculator helps cyclists determine the gear ratio of their bicycle — the relationship between the number of teeth on the chainring and the rear cog. Understanding gear ratios helps optimize cadence and climbing performance.
Gear Ratio: 0
A higher gear ratio means more distance per pedal revolution, suitable for high-speed flats. Lower ratios make climbing easier and help maintain a steady cadence uphill.
