Abstract
A rear derailleur is provided for the coaxial attachment on a portion of a bicycle frame rear tail while using an adapter that includes an adapter bolt and an adapter nut and has a dual-arm base element, a pivoting mechanism, a movable element and a chain guide assembly. The reference is distinguished by at least one engagement element which facilitates an indirect frictional engagement between the adapter nut, on the one hand, and at least one of a) an inner first arm of the base element, b) an axial internal side of the mounting portion and c) the adapter bolt, on the other hand. Said engagement element, in a defined pre-assembled state, acts in the sense of a reinforcement of a consequential rotational force being able to be exerted on the base element by the adapter bolt and the adapter nut.
