Abstract: A sprocket wheel for a bicycle includes a first main surface, which is flat in one or more sections, and a second main surface, which is situated opposite the first main surface. The second main surface is flat in one or more sections and extends parallel to the first main surface in one or more sections. The sprocket wheel also has an outer circumferential surface, which connects the first and the second main surface to one another and on which toothing is provided.

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.
