Bicycle chains, chainrings and cassettes for single and multi-speed bikes.
Chains, chainrings and cassettes wear together, and a worn chain stretches, which causes poor shifting, chain slip and faster wear on the cassette and chainrings. Check chain wear regularly with a chain checker and replace it before it damages other parts. Chains must match the number of gears on your bike, such as single-speed, 8, 9, 10, 11 or 12-speed. Cassettes and chainrings come in different tooth counts, which change gear ratios for climbing or speed. Check compatibility with your drivetrain before ordering. Quick links make chain installation and removal easier. Clean and lubricate the chain regularly.
