US Patent 11485449 Bicycle cassette with locking connection

A bicycle cassette comprises two segments that are attached together thereby forming a composite cassette that can be attached to a rear bicycle hub driver body. The bicycle cassette allows for the use of a smaller sprocket on one segment of the cassette because the smaller sprockets can overhang the hub driver body. Specifically, the cassette allows a small 9 or 10 tooth sprocket to overhang the cassette driver body on the bicycle hub by attaching a small sprocket assembly to a larger sprocket assembly using a locking, bayonet style attachment.
