A crucial component of the shifting is the sprocket. The number of individual pinions are combined to form a so-called bicycle cassette or sprocket cassette. The corresponding number of pinions on the rear wheel affect the specifications of the other components such as chain, chain ring and its width, rear derailleur and shift lever. In our assortment, you will find a large selection of different sprockets, from one to eleven pinions per cartridge. The more gears are attached to the rear wheel the less space is between each gear, since the available space on each bike is about the same.
