ABSTRACT:
A rear derailleur for a bicycle includes a base member for attaching the derailleur to the bicycle, a movable member for supporting a chain guide, a linkage mechanism coupling the base member to the movable member so that the movable member is capable of movement relative to the base member, a biasing mechanism for biasing the movable member toward a wheel of the bicycle, and an actuating member for coupling to a control cable of the type having an inner wire that slides within an outer casing so that pulling the inner wire causes the movable member to move away from the rear wheel of the bicycle against the biasing of the biasing mechanism and releasing the control cable causes the movable member to move toward the rear wheel of the bicycle in accordance with the biasing of the biasing mechanism. A shock absorber is coupled in a path between the control cable and the movable member for allowing the movable member to move relative to the base member when an external force having a component directed toward the rear wheel is applied to the derailleur.
