Abstract
A bicycle rear derailleur has a base member mountable to a bicycle frame, a movable member movably coupled to the base member, a chain guide assembly rotatably connected to the movable member, a biasing element configured to bias the chain guide assembly in a first rotational direction relative to the movable member, and a damper device disposed between the chain guide assembly and the movable member. The damper device is operable to apply a damping force to the chain guide assembly when the chain guide assembly rotates in a second rotational direction relative to the movable member. The damper device includes a friction member having a first end and an outer annular surface. The first end is non-rotatably attached to the chain guide assembly. The outer annular surface of the friction member is in frictional engagement with an inner annular surface of the movable member.
