Multi-sprocket arrangement for a rear wheel assembly for a bicycle, and rear wheel assembly

A rear wheel assembly for a bicycle with a derailleur system, the rear wheel assembly comprising:

• a rear wheel hub which can be arranged between two opposite frame portions of a bicycle frame;
• a driver which is attached rotatably to the rear wheel hub;
• and
• a multi-sprocket arrangement, which is coupled to the driver for conjoint rotation, comprising at least eleven sprockets with differing numbers of teeth,
• wherein each sprocket has an inner side surface and an outer side surface in the region of the teeth and a sprocket center plane lying between the inner side surface and the outer side surface and extending orthogonally with respect to the axis of rotation,
• wherein the multi-sprocket arrangement is configured such that, in the mounted state, at least two sprockets with the smallest numbers of teeth are formed in a radially self-supporting manner and are coupled to the driver via at least one further sprocket with a greater number of teeth, and the three sprockets with the smallest number of teeth are arranged in such a manner that a sprocket center plane of the sprocket with the third smallest number of teeth runs in the region of an axial end surface of the driver or axially outside the driver.

A rear wheel assembly and a bicycle frame for a bicycle with a derailleur system, wherein the rear wheel assembly comprises:

• a rear wheel hub which is arranged between two opposite frame portions of the bicycle,
• a driver which is coupled rotatably to the rear wheel hub, and
• a multi-sprocket arrangement which is coupled to the driver for conjoint rotation and has at least eleven sprockets with differing numbers of teeth, wherein each sprocket has an inner side surface and an outer side surface in the region of its teeth and a sprocket center plane lying between the inner side surface and the outer side surface and running orthogonally with respect to the rear wheel hub,
• wherein the multi-sprocket arrangement is designed in such a manner that, in the mounted state, with an axial length of the driver from a driver stop to an axially outer end side in a range from 28.5 mm to 30.5 mm, preferably 29.5+/−0.2 mm, the following applies:
• a first distance in the axial direction from the driver stop to the outer side surface of the sprocket with the smallest number of teeth is greater than 37.4 mm, is preferably greater than 38.0 mm, is even more preferably 39.9+/−0.2 mm, or/and a second distance in the axial direction from the axially outer end side of the driver to an outer side surface of the sprocket with the smallest number of teeth is greater than 9.1 mm, is preferably 10.4+/−0.2 mm, or/and a fourth distance in the axial direction from the outer side surface of the sprocket with the smallest number of teeth to a circumferential surface at the rear dropout of the bicycle frame, which circumferential surface is adjacent to the rear wheel assembly and is closest thereto, is smaller than 8.35 mm, is preferably 7.35+/−0.15 mm, or/and a fifth distance in the axial direction from the outer side surface of the sprocket with the smallest number of teeth to a recessed surface at the rear dropout of the bicycle frame, which surface is adjacent to the rear wheel assembly and runs orthogonally with respect to the rear wheel hub, is smaller than 11.5 mm, is preferably 10.55+/−0.15 mm.
