Sprocket Assembly

Abstract

The invention relates to a sprocket assembly for mounting on a driver of a rear wheel hub of a bicycle. By means of a threaded element, a sprocket cluster and a separately embodied ring element are axially clamped together, and a rotation-coupling device is provided between the sprocket cluster and the ring element. Knurled teeth features on the threaded element and ring element prevent the loosening of the threaded element. Through the separate embodiment of the ring element and sprocket cluster, the respective most suitable manufacturing methods can be used for the two parts and, in the event that the sprocket cluster is manufactured by means of machining methods, the knurled features on the ring element can also be produced in a cost-effective and precise manner through shaping methods.
