Abstract

A multi-sprocket arrangement for installation on a rear wheel axle of a bicycle includes a sprocket assembly. The sprocket assembly has at least a first sprocket and a second, self-supporting sprocket. The second sprocket is connected to a holding body via the first sprocket by way of a separate, cylindrical fastener which extends parallel to the rear wheel axle. The fastener has a first and a second end which are connected in frictionally fit fashion to drilled holes in the first and second sprockets. The frictionally fit connection between the fastener and the drilled holes of the sprockets prevents an axial movement of the first and second sprockets toward one another. The fastener is additionally connected, at the first and second ends, in form-fitting fashion, to the first and second sprockets such that an axial movement of the first and second sprockets away from one another is also reliably prevented.
