Gear Ratio Formula Bike, The number is derived from a simple formula: (chainring size / cog size) X (wheel size X PI).

Gear Ratio Formula Bike, Gear ratios can be calculated from the following formula, where CT stands for chainring teeth, ST for sprocket teeth, and GR for gear ratios. CT / ST = GR When should gear ratios be used? Gear ratio is the most simple system when it comes to comparing gearing on bicycles. The defining component is the chainring-sprocket tooth count pair — the number of teeth on each sets the gear ratio directly, and that ratio decides how much road the bike covers per pedal stroke.
