BicycleSource.com Gear Calculator

The gearing calculator produces a table listing each gearing combination for a given set of sprockets. This is a great way to examine your existing combination, or to decide upon a new one that minimises duplication and gaps.

Instructions: Click the checkboxes for the number of teeth on your front rings and rear cogs, and a table with gear-inches for each combination will be generated.
