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 bicycle control assembly may be provided for operating an electromechanical gear shifting device. The control assembly includes a graspable housing mountable to the bicycle, a power supply connected to the control assembly disposed in the housing, a first operating member movably connected to the housing, and electronic componentry disposed on the first operating member. The electronic componentry may include an electrical switch, a controller in communication with the electrical switch and configured to generate a signal to change a shift position of the gear shifting device responsive to an input from the electrical switch, and an antenna in communication with the controller and configured to send the signal. The control assembly may also include a cable extending from the housing to the first operating member connecting the power supply and the electronic componentry.

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 bicycle front shifting system includes operable to transmit a wireless signal, a crank assembly with two crank arms and a pedal on each of the two crank arms. The crank assembly is rotatable about a rotation axis. A front shift unit is coupled to the crank assembly and is rotatable about the rotation axis. The front shift unit includes a chain ring component with a big chain ring and a small chain ring. The small chain ring has a small diameter and the big chain ring has a big diameter that is larger than the small diameter. A shift mechanism is coupled to and rotatable with the chain ring component about the rotation axis. The shift mechanism is configured to receive the wireless signal from the shifter and to shift a chain between the big chain ring and the small chain ring according to the wireless signal.

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.
