Abstract
A multiple-sprocket arrangement for mounting on a rear wheel axle of a bicycle includes a receiving body designed for mounting on the rear wheel axle, and a sprocket assembly. The sprocket assembly includes a first sprocket, the inner diameter of which is greater than an outer diameter of the receiving body and which is connected to the receiving body. The sprocket assembly further includes at least one second sprocket, the inner diameter of which is smaller than an outer diameter of the receiving body and which is designed in an unsupported manner and connected to the receiving body in a torque-transmitting manner by means of the first sprocket. The first sprocket and the at least one second sprocket may be of a one-piece construction.
