A bicycle rear derailleur includes a movable member and a chain guide assembly rotatably connected to the movable member. The bicycle rear derailleur also includes a pivot member non-rotatably coupled to the chain guide assembly and having an outer annular surface, a biasing device 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 device that is radially inner relative to the biasing device. The friction device includes a friction member having at least one friction surface biased against and in frictional engagement with the pivot member.
A bicycle rear derailleur comprising:
A damper device for a bicycle rear derailleur, the damper device being disposable within a movable member of the bicycle rear derailleur, the damper device operable to apply a damping force to a chain guide assembly rotatably attached to the movable member via a pivot member as the chain guide assembly rotates in a rotational direction relative to the movable member, the damper device comprising:
