Calculate bike gear ratios, cadence speed, rollout and gear gaps for road, mountain and commuter bikes, fully offline.
Bike Gear Ratio Calculator is built for cyclists, mechanics and bike upgrade users who need to check gearing before changing chainrings, cassettes, wheel size or tires.

- Chainring and cassette combination comparison
- Gear gap and duplicate gear hints
- Climbing, cruising and commuting templates
- Road, mountain and commuter bike presets
