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 for rotation about a rotational axis, a biasing element configured and arranged to bias the chain guide assembly for rotation in a first rotational direction with respect to the movable member, and a fluid damper having a fluid cavity 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 opposite to the first rotational direction. The fluid damper has a guide wheel configured to route a chain and rotatable about the rotational axis.

A damper assembly includes a cylinder defining a chamber. The damper assembly includes a body supported by the cylinder and having a first surface and a second surface opposite the first surface. The body defines a passage extending from the first surface to the second surface. One of the first surface or the second surface define a slope at the passage. The damper assembly includes a check disc at the slope, the check disc selectively restricting fluid flow through the passage.

The present disclosure relates to a vibration damper for a vehicle, comprising a damper tube filled with hydraulic fluid, a working piston, which is connected to a piston rod and is arranged movably back and forth within the damper tube. An interior of the damper tube is divided by the working piston into a first working chamber and a second working chamber, a closure package, which closes off the damper tube fluid-tightly on the piston rod side, an adapter, which is fitted inside the damper tube and is intended for attaching a damping valve device, and a compression stop assembly with an auxiliary piston, which is arranged axially movably within the damper tube. The auxiliary piston is arranged between the adapter and the end of the damper tube away from the piston rod.
