Abstract: A seat post assembly for a bicycle has a first tube with a first distal end and a second tube with a second distal end. The first and second tubes are movable relative to one another to establish a distance between the first and second distal ends. A first pressure chamber has a loaded pressure proportional to a load applied along the tube axis. A second pressure chamber has a second pressure not proportional to the load. A flow path connects the first and second pressure chambers. A valve is disposed along the flow path and is configured to move between a closed position closing the flow path and an open position opening the flow path between the first and second pressure chambers. An isolator of the valve is configured to nullify any resultant force produced by the loaded pressure of the first pressure chamber acting on the isolator.

Abstract: Example bicycle disc brake rotors are described herein. An example disc brake rotor described herein includes a core having a brake surface core portion and a single-piece brake track coupled to the brake surface core portion. The brake track is constructed of stainless steel. The brake track includes a first track on a first side of the brake surface core portion, a second track on a second side of the brake surface core portion, and a connecting portion extending over a peripheral edge of the brake surface core portion between the first and second tracks.

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.

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 pressure measuring device for a bicycle has a housing that includes a pressure chamber. The pressure chamber has a valve disposed in a first opening and a second opening into or out of a tire assembly volume of a tire assembly. A sense element is in pressure communication with the pressure chamber along a flow path between the first and second openings.
