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 having a tool interface on an inner circumferential surface of the locking screw arrangement for engaging a tool in a torque-transmitting manner,
• wherein the multi-sprocket arrangement is configured to be torque-transmitting coupled to the 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 a 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 shaft portion having a one-piece construction with the axially outer stop portion and the at least one external thread, the at least one-external thread configured to be screwed into an associated internal thread to fix the locking screw arrangement,
• wherein the at least one-external threads 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 sprocket of the at least two smallest sprockets,
• wherein the multi-sprocket arrangement of the multi-sprocket assembly is non-rotatably coupled to the driver.
