Gearing Calculators
Coded, in JavaScript, by Scott Rose
Enter the weight of your rig-- bike, gear, and self-- the cadence you like to keep, your power output, and a grade-- and click on the "crank" button to compute the required gear ratio. I've provided some reasonable defaults; just type over them with your own values. And takes your wheel size, chainring size, and freewheel size and computes the gear ratio.
