## How Bike Gear Ratios Work
### Formula
**Gear Ratio = Chainring Teeth / Cog Teeth**
**Development = Gear Ratio x Wheel Circumference**
Development tells you how far the bike travels per pedal revolution. Higher gear ratios mean more distance per revolution but require more force.
### Gear Inches
Gear inches is a traditional measure: **Gear Inches = Gear Ratio x Wheel Diameter (inches)**.

हल किया गया उदाहरण
A road bike with a 50-tooth chainring, 17-tooth rear cog, and 700mm wheels.
- Gear ratio = 50 / 17 = 2.94
- Wheel circumference = 700 * 3.14159 = 2199 mm = 2.199 m
- Development = 2.94 * 2.199 = 6.47 m per pedal revolution
- At 90 RPM: 6.47 * 90 * 60 / 1000 = 34.93 km/h = 21.71 mph
