By Bruce Wells updated 2023-11-02
If you've ever wondered how to build a better gear profile for your bike, this is where to begin. Simply input the cassette you use and the chainring sizes and Presto! - You get your gear ratios.
You can add custom sizes, tires, etc. or pull-down from the menus.
Title your configuration and it will show in the browser tab so you can have several 'up' at once to compare.
Download into CSV format or print too!
