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: A control device for a hydraulic brake for a bicycle includes a reservoir for hydraulic fluid. The reservoir has a variable volume. The control device also includes a reservoir cover at least partially defining the reservoir, and a support that is attachable to a handlebar of the bicycle via an inner annular surface of the support. A handlebar proximity zone is radially outer relative to the inner annular surface of the support and is within two centimeters of the inner annular surface of the support. At least part of the reservoir cover is within the handlebar proximity zone.

Abstract: A bicycle with an electric pedal assist motor capable of driving a chainring independent of cranks includes wheel speed sensors and crank cadence sensors. The wheel speed sensors and the crank cadence sensors measure wheel speed and crank cadence, respectively, and provide the measured wheel speed and crank cadence to controller of the bicycle. The controller activates motor overdrive based on the measured wheel speed and/or the measured crank cadence.

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: An electromechanical control system for a bicycle has a switch device, the switch device operating a switch between at least three positions. A control communication device transmits signals responsive to operation of the switch. The electromechanical control system includes an operation device configured to respond to signals transmitted by the control communication device. Signals transmitted by the control communication device include commands to listen and commands to operate.

Abstract: An apparatus for determining bicycle pedaling may include a sensor that detects the angular velocity and/or position of a drivetrain or rear sprocket assembly of the bicycle The apparatus may determine values indicative of pedaling. The apparatus may be configured to be housed within a component of the bicycle, such as within a hollow opening of the spindle or crank axle. The apparatus also may include a wireless transmitter to communicate with another component, such as a suspension controller.

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: A gear change mechanism for a bicycle may involve a tensioner that has a wheel engaged with a chain in a bicycle drivetrain. This tensioner may be configured to rotate or otherwise change orientation in response to slack in the chain to maintain tension in the chain. A sensor may be used to measure the orientation of a tensioner of a chain in a bicycle drivetrain, and/or the physical orientation of components indicative thereof. Actions may be triggered by signals generated by the sensor.

Abstract: Responsive to a hydraulic piston advancing out of a piston housing in a second brake arm and contacting a piston cam surface of a first brake arm, the second brake arm pivots around a second pivot. As this is happening, a cam surface in the second brake arm lifts a contact surface of a first force transfer member of the first brake arm, imparting torque to the first brake arm which then pivots around a first pivot. The cam surface is shaped to impart synchronous motion to the first and second pad holders. Splitting one of the brake arms with a centering member permits a centering adjust feature.
