Multi-sprocket assembly and rear wheel assembly for a bicycle with a derailleur system

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

• a rear wheel hub which can be arranged between two opposite frame portions of a bicycle frame,
• a driver rotatably coupled to the rear wheel hub;
• and
• a multi-sprocket assembly comprising:
• a multi-sprocket arrangement, and
• a locking screw arrangement,
• wherein the multi-sprocket arrangement is configured to be torque-transmitting coupled to a driver of the rear wheel assembly, and comprises at least eleven sprockets with differing numbers of teeth,
• wherein the multi-sprocket assembly is configured such that, in the mounted state, at least two of the smallest sprockets are axially fixed to the driver via the locking screw arrangement,
• wherein the locking screw arrangement has a shaft portion for receiving at least one sprocket of the at least two smallest sprockets,
• wherein the shaft portion has an axially outer stop portion at one end region and at least one external thread at an opposite end region, the at least one external thread configured to be screwed into an associated internal thread to fix the locking screw arrangement,
• wherein the external thread of the shaft portion has an outer diameter which is larger than an outer diameter of a region of the shaft portion that receives the at least one of the at least two smallest sprockets,
• wherein the multi-sprocket arrangement of the multi-sprocket assembly is non-rotatably coupled to the driver.
