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 seat post assembly includes a seat post that is electrically adjustable in height. The adjustability may be based on one or more pressures sensed by one or more sensors within the seat post assembly, respectively. The disclosed seat post assembly includes an electronics module. The electronics module may be carried under the seat or saddle and may include a pressure sensor or pressure sensor circuitry.

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.

Abstract: Example pedal detection devices for bicycles are described herein. An example a pedal detection device includes an electronics module to be disposed in a spindle of a crankset of the bicycle. The electronics module includes a sensor to detect angular velocity and/or position of the spindle, a driver, and an expander wedge movably coupled to the electronics module via the driver. Axial movement of the expander wedge relative to the electronics module causes the expander wedge to expand radially.

Abstract: Example brake systems and apparatus for providing pitch control on bicycles are described herein. An example rear brake caliper described herein includes a caliper housing to be coupled to the bicycle. The caliper housing includes a first port to be fluidly coupled to a first fluid line fluidly coupled to a front brake actuator and a second port to be fluidly coupled to a second fluid line fluidly coupled to a front brake caliper. The rear brake caliper also includes a valve between the first port and the second port. The valve is operable to affect fluid flow between the first port and the second port.

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 fluid device for a bicycle may be provided to vent fluid from a hydraulic chamber of a seating component such as an adjustable seating assembly for a bicycle. The fluid device may be operable to vent a compressible fluid or a mixed combination flow of compressible and non-compressible fluids in a metered volume. The fluid device may recycle fluids preferentially.

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 compensation device in fluid communication with the fluid cavity and is configured to accommodate a change in the volume of fluid in the fluid cavity.
