Bike Gear Ratio Visualizer

How it helps

Use it for a focused task

Enter your chainring, cassette, wheel size, and crank length to instantly see every gear combination visualized. The main chart shows speed at four common cadences (60, 80, 90, 100 RPM) so you can spot gaps and overlaps at a glance.

A gradient estimate tells you what climb each gear can handle. Switch to comparison mode to line up two drivetrain setups and see exactly what you gain or lose before buying new parts.

Pick a preset that matches your bike type, or type in your own chainring and cassette teeth. Choose your wheel size from the dropdown or enter a custom tire.
