Boxes

A cassette is the gear set on the rear axle of your bicycle. It consists of multiple sprockets that, together with the derailleur and chain, form the gears. The more teeth the largest sprocket has, the lower your lowest gear — useful on hills or with a heavy load.

Choose the cassette based on the number of gears your bike has (9-, 10-, or 11-speed) and the gear ratio (such as 11/42 or 11/50) that suits your riding style and terrain. Also, ensure that the cassette is compatible with your hub and groupset. On this page, you will find a wide range of cassettes for various bikes.
