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 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.

Abstract: A bypass device for a seating component such as an adjustable seating assembly for a bicycle may be provided to redistribute fluid preferentially by density. The bypass device may be operable to redistribute a low density compressible fluid or a mixed phase of low density compressible and high density non-compressible fluids within the seating component.

Abstract: An electromechanical rear derailleur is provided for a bicycle, including a base member for attachment to the bicycle. A movable member has a cage assembly attached thereto. A linkage is provided that couples the movable member to the base member and operative to enable movement of the movable member relative to the base member in a direction substantially parallel to the mounting axis. A power source powers an motor module connected thereto to move the movable member and elements thereon.
