Buy Cassettes, Sprockets, and Sprocket Packs Affordably at the Bicycle Online Shop of starbike.com

A cassette (also called a sprocket or sprocket pack) is always mounted on the freehub of the rear wheel hub in a derailleur system and consists of 7 to 11 individual sprockets. The sprocket pack, in combination with the derailleur, is responsible for the fine-tuning of the gear shifting.

In the past, cassettes were manufactured as complete sprocket packs, but today smaller sprocket packs (3 to 4 sprockets, for example, in a Shimano XT cassette) or individual sprockets are used, which makes replacement easier in case of wear or damage.

The sprockets are placed onto the freehub of the rear hub and secured with a lockring. There are two different freehub standards: Shimano or SRAM on the one hand and Campagnolo on the other. It is essential to ensure that Shimano and Campagnolo freehubs are not compatible with each other! The type of freehub is always listed in the product name on our site.
