How Do the Gears Work on a Mountain Bike: A Comprehensive Guide
Mountain bikes typically have two sets of gears: the front gears (also called chainrings) and the rear gears (also called the cassette). By switching between different gears on the chainrings and cassette, riders can effectively change the bike’s gear ratio, making it easier or harder to pedal depending on the terrain. The gears work by shifting the bike’s chain from one gear to another, which changes the distance that the bike travels with each rotation of the pedals. The lower the gear, the easier it is to pedal up steep hills or off-road terrain, while the higher the gear, the faster the bike can travel on flat, smooth roads.
