The piston assembly is disposed within the piston chamber, wherein a movement of the piston assembly causes a gas separated from a liquid within the variable volume to flow through the fluid passageway, through the valve, and into the fluid chamber.

Abstract: A saddle clamp assembly includes a lower cradle, an upper cradle supported by the lower cradle, and a left pivot block and a right pivot block each independently, rotatably coupled with the lower cradle, the left pivot block and the upper cradle, and the right pivot block and the upper cradle to secure a left saddle rail and a right saddle rail, respectively, of a saddle for a bicycle therebetween.

Abstract: An air filter assembly for a height adjustment seat post including a lower tube and an upper tube telescopically supported within the lower tube includes a lower cap within an end of the lower tube of the height adjustment seat post, a filter within the end of the lower tube, and a filter retainer to retain the filter within the end of the lower tube, the filter to filter air expelled or ingested through the end of the lower tube through the lower cap.

Abstract: A pressure relief valve for a height adjustment seat post including a lower housing, a stanchion telescopically supported within the lower housing, and a cartridge including a piston rod driven by a piston to telescopically adjust the stanchion relative to the lower housing includes a pressure relief port in the piston of the height adjustment seat post, a pressure relief valve ball, and a pressure relief valve spring to bias the pressure relief valve ball to a closed position to close the pressure relief port.

Abstract: A multi-tool system includes a multi-tool sleeve assembly including a storage sleeve and an end cap to be inserted into an open end of the storage sleeve, with one of a bit driver multi-tool or a chain break multi-tool to be stored in the storage sleeve of the multi-tool sleeve assembly.

Abstract: A linear actuator system includes a linear actuator including an outer body, an inner body disposed within the outer body, a fluid chamber at least partially extending between the inner body and the outer body, a piston chamber extending at least partially within the inner body, a valve configured to selectively fluidly couple the fluid chamber and the piston chamber to each other, a piston assembly including a piston, a variable volume within the piston chamber that extends between the piston and the valve, and a gas collector assembly including a fluid passageway. The piston assembly is disposed within the piston chamber, wherein a movement of the piston assembly causes a gas separated from a liquid within the variable volume to flow through the fluid passageway, through the valve, and into the fluid chamber.

Abstract: A control device includes an actuation lever, a bearing mounted in the actuation lever, an axle extended through the bearing, and a base supported by the axle, whereby the actuation lever is rotatably coupled with the base, via the bearing and the axle, for rotation relative to the base.
