Bike cassettes give your bike the functionality and technical prowess needed for climbing and descending terrain. A bike cassette is a cluster of gears that sits at your bike's rear hub, and the derailleur shifts the chain up and down depending on the gear change as you ride. The range of bike cassettes has a selection of components designed for the needs of you as a cyclist and the terrains you are setting out on, starting at 7 speed and spanning up to 11 speed. Bike cassettes wear over time and will occasionally need replacing. When replacing a bike cassette, ensure the speed and number of teeth match the existing cassette. The selection of components includes premium brands that blend technology and performance, such as Miche bike cassettes, which manufacture their products in Italy and have a wealth of experience crafting technical components that enhance performance.
