How Do Mountain Bike Gears Work? A Comprehensive Guide for Beginners
Mountain bike gears work by changing the ratio of pedal revolutions to rear wheel revolutions, allowing you to cycle up hills or down them. A chain turns the front and rear gears, and choosing a different size front chainring or rear cassette will result in a different gear ratio. Shifters control the chain movement between gears, with the left shifter typically controlling the front gears and the right shifter controlling the rear gears. By shifting the gears, you can find the perfect balance of power, speed, and endurance for any terrain.
