The invention relates to a damping device on a multi-gear cassette for a rear wheel of a bicycle, wherein percussive forces produced by the chain members running from the slack span of the chain onto the sprocket are damped. This is achieved by damping the chain in the region of the chain run-in on the sprocket where no loads are borne. In one embodiment, a damping ring is provided for the purpose of supporting the chain link plates, and the tooth contour of the tooth flank which does not transmit load force is set back, and the tooth root space according to the invention is recessed toward the hub center. As such, when the chain is fed in to the sprocket, the chain link plate contacts the damping ring rather than the chain roller impacting the tooth flank or the tooth base.
