Gear ratio explorer
Compare ratios, gear inches, rollout and speed at a chosen cadence.
Your inputs
Calculate a starting point.
Estimated result
Supporting information
Know what shapes the result.
Ratio is chainring teeth divided by sprocket teeth. Development multiplies that ratio by wheel circumference; cadence then converts rollout into speed.
Best used for
A practical starting point
Comparing a gear, cadence and wheel-size combination before changing a cassette or chainring.
Limitations
Check the context
The result is mathematical gearing, not a prediction of sustainable speed. Loaded tyre diameter and drivetrain condition change real-world results.
