A multiple sprocket assembly for assembly in a torque-transmitting manner in terms of a bicycle rear axle on a bicycle rear wheel driver device, and a modular system for generating multiple sprocket assemblies. The multiple sprocket assembly comprises an inboard terminating sprocket arrangement, a first sprocket cluster which is connectable to the inboard terminating sprocket arrangement, and an outboard terminating sprocket arrangement. The first sprocket cluster is configured to be rotatable on an outboard side in relation to the driver device by a rotational bearing device of the multiple sprocket assembly.

Multiple sprocket arrangement and modular sprocket arrangement system

A bicycle sprocket for a sprocket cassette comprises a sprocket main body which extends about a virtual sprocket axis about which the sprocket is rotatable during intended operation on a bicycle. In the case of a single release tooth being formed, a release-side stabilizing tooth is arranged in the circumferential region of extent of an upshift recess formation. The release-side stabilizing tooth has an inner tooth contact surface which has a greater axial spacing to an axial reference position than an inner tooth contact surface of the reference tooth. Additionally, or alternatively, in the case of a single catch tooth being formed, a receiving-side stabilizing tooth is arranged in the circumferential region of extent of a downshift recess formation. The receiving-side stabilizing tooth has an inner tooth contact surface which has a greater axial spacing to the axial reference position than the inner tooth contact surface of the reference tooth.

Bicycle sprocket

A bicycle rear wheel sprocket arrangement comprises a carrier sprocket and a self-supporting sprocket cluster connected to the carrier sprocket on the outboard side in a connection region of the carrier sprocket. The sprocket arrangement comprises a plurality of further sprockets which are designed as sprocket rings. The sprocket rings are each arranged on the carrier sprocket in the connection region and each are connected to the carrier sprocket.
