    摘要: A transmission element 1 (driver) for transferring torque from a set (3) of sprockets (5) to a bicycle rear wheel hub (9) bearing-supported on a wheel axle (7) is equipped with a first interface (13) for coupling to the sprocket (5). This first interface is arranged such that it secures the sprocket or the cassette to the driver in axial and/or radial and/or tangential direction. The driver (1) is furthermore equipped with a second interface (15) for coupling to the sprocket (5). The second interface is arranged such that it secures the sprocket to the driver in axial and/or radial and/or tangential direction. The second interface (15) is then present in a larger diameter than the first interface (13).
