A set of sprockets (called a "cassette") is mounted onto a splined shaft of the freehub to engage the chain. The ratcheting mechanism is a part of the hub, in contrast to a freewheel , an older technology, which contains both the sprockets and a ratcheting mechanism in a single unit separate from the hub.
