Bicycle Gear Calculator

Although the GearCalc Pro Bicycle Gear Calculator is a very powerful application for serious cyclists, it is also fun and easy to use. It creates charts, tables, and graphs for your bicycle in English/American and Metric Standard Gearing. It will calculate speed, and cadence, and gearing step sizes. It has automatic suggest functionality for both gear usage and freewheel/cassette cog sizes. It quickly and easily calculates the speed range for each gear. The gearing assessment also gives the optimum speed for each gearchange along with the cadence that this corresponds to.

If this sounds far too easy you can always use some gear ratio charts and suffer.
