The Track Cycling Gear Calculator allows users to input their inventory of chainrings and cogs for both track and/or road bikes and it will use them to calculate target gear-inches, gear-meters, or gear ratios.

The app also has a standard gear calculator function where one enters chainring and cog combinations and the app outputs gear-inches, gear-meters, and gear ratio.

This app was designed and developed by an avid track racer and coach.
