Abstract

The disclosure describes an electromechanical rear derailleur for coaxial mounting on a rear wheel axis. The rear derailleur has a base member, a pivot mechanism, a movable member having a chain guiding arrangement, and an electromechanical drive for driving the pivot mechanism. The pivot mechanism connects the base member to the movable member. The chain guiding arrangement is connected to the movable member for rotation about an axis of rotation. The base member comprises a first connection end, which can be mounted coaxially with the rear wheel axis, and a second connection end for coupling with the pivot mechanism.
