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. The locking screw arrangement has a shaft portion for receiving at least one sprocket of the at least two smallest sprockets. 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. 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 sprocket of the at least two smallest sprockets.
