A bicycle rear derailleur (80) has a base member (86) mountable to a bicycle frame (52), a movable member (88) movably coupled to the base member, a chain guide assembly (92) rotatably connected to the movable member for rotation about a rotational axis (R), a biasing element (204) configured and arranged to bias the chain guide assembly for rotation in a first rotational direction (T) with respect to the movable member, and a fluid damper (90) having a fluid cavity (122) containing a volume of fluid. The fluid damper is operatively disposed between the chain guide assembly and the movable member to apply a damping force to the chain guide assembly when the chain guide assembly rotates in a second rotational direction (D) opposite to the first rotational direction. The fluid damper has a guide wheel (104) configured to route a chain and rotatable about the rotational axis.
