Cassettes & Sprockets

Like a gearbox in a car, a cassette provides the bike with its gear ratios and works together with the chain to transform rider input into motion. Cassettes attract more than their share of grime and dirt from use, this can speed up the wearing process. If the cassette is badly worn then the chain may well also need replacing. Cassettes can last for two to three chains if they are properly cleaned and lubricated.
