MTB Gear Ratio
Calculate gear ratio, cadence, and gain ratio for every gear in your setup. Configure multiple front and rear cogs and compare drivetrains side-by-side — so you pick the right cassette and chainring for the trails you actually ride.
Speed-vs-cadence graphed for every chainring/cog combo in your drivetrain. Spot duplicate ratios, find the gaps, and pick the cassette that gives you the spread you actually need.
Configure any combination of front chainrings and rear cassette teeth. 1x, 2x, 3x — whatever you ride. Save multiple setups to compare your current drivetrain against an upgrade you're considering.
Numeric gear ratios, gain ratios, and development per gear. Compare two setups side-by-side to see exactly which gears you'd gain or lose.
Pick a target cadence and see what speed each gear gets you. Pick a target speed and see what cadence you'd need. Especially useful for sizing climb gearing — figure out the lowest gear that keeps you spinning.
