Abstract:
A bicycle rear wheel sub-assembly having a sprocket-carrying body, a cogset including a plurality of axially adjacent sprockets with at least three of the plurality of sprockets formed into a monolithic set and a ring nut securing the cogset to the sprocket-carrying body. The ring nut is formed as two parts assembled together—an axially outer first part on which a tubular body and a flange are formed, and an axially inner second part on which a threaded portion is formed. This structure provides a simple and effective coupling of the ring nut with the monolithic sub-set of the cogset and the sprocket-carrying body.
