About Bike Gears
Bike gears allow you to maintain an optimal pedaling cadence across different speeds and terrains. Understanding gear ratios helps you choose the right gear for your riding conditions.
Key Concepts:
Gear Ratio: Chainring teeth รท Cassette teeth
Gear Inches: Effective wheel size considering gear ratio
Development: Distance traveled per crank revolution
Gain Ratio: Leverage advantage of the gear
Gear Classifications:
High Gear (100+ inches): Fast, hard to pedal, good for descents
Medium Gear (70-100 inches): Balanced, good for flat terrain
Low Gear (Below 70 inches): Easy to pedal, good for climbing
