Abstract

See full text

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.
