Abstract: A bumper carrier for a suspension fork includes a base plate and a retention feature. The retention feature may be configured to secure a bottom-out bumper to the bumper carrier. In some aspects, the retention feature comprises an annular wall integral with the base plate, which may at least partially nest the bottom-out bumper. The annular wall can define an annular notch surrounded by protrusions to retain the bottom-out bumper. The base plate may include apertures for coupling to a topcap. In some implementations, the bumper carrier includes at least one elastomeric portion permanently affixed to the base plate, which may be overmolded or adhesively bonded.

Abstract: A suspension fork for a vehicle includes an upper tube and a lower tube slidably engaged with the upper tube collectively defining an interior. A topcap is positioned on the upper tube. A bottom-out assembly is disposed within the interior and comprises a bumper carrier positioned proximate to the topcap and an elastomeric bottom-out bumper affixed to the bumper carrier. An air pressure relief assembly can be integrated with the topcap. The suspension fork provides improved bottom-out protection and air pressure relief.

Abstract: A suspension fork includes a lower tube, an upper tube telescopically engaged with the lower tube, and an air-spring assembly disposed within the lower tube and the upper tube. The air-spring assembly includes a positive air chamber, a negative air chamber, a piston dividing the positive air chamber and the negative air chamber, and a sealhead positioned proximate the negative air chamber. The sealhead includes an outer wall and an inner wall defining an aperture in which a shaft coupled to the piston is movably received. A hollow chamber is positioned between the outer wall and inner wall. A topout plate comprising a plurality of openings in communication with the hollow chamber is attached to the sealhead. The hollow chamber of the sealhead increases a volume of the negative air chamber, providing improved suspension performance.

Abstract: The present disclosure provides a suspension fork comprising a fork leg comprising an upper tube and a lower tube slidably engaged with one another for compression and rebound, a damper assembly positioned within the fork leg, the damper assembly comprising a shaft and a sealhead coupled to the shaft, and a reservoir configured to retain bath oil in proximity to the sealhead. The sealhead is sized and positioned to splash bath oil upwards when the sealhead is driven into the bath oil during the compression of the suspension fork. The sealhead comprises a base portion and a leading portion tapering downwards from the neck. The hydrodynamic profile of the sealhead creates controlled oil displacement patterns that distribute lubricating oil to internal components including bushings, seals, and sliding surfaces during suspension movement.

Abstract: A suspension system includes an upper tube, a lower tube slidably engaged with the upper tube, and an air spring assembly disposed within the lower tube. The air spring assembly comprises an air piston positioned within a cylinder configured to retain an amount of bath oil, an air inlet positioned on a lower end of the cylinder, an extension tube in communication with the air inlet, and an air exit aperture positioned on the extension tube at a location above a maximum fill amount of the bath oil. The suspension system provides improved air spring performance and lubrication in an inverted fork configuration.

Abstract: A damper valve with an adjustable effective stiffness of a shim. The damper valve includes a piston. The piston has a fluid path formed therethrough. A shim is disposed proximate the fluid path formed through the piston. A stiffness adjustment feature is coupled to the shim, and the shim is disposed between the piston and the stiffness adjustment feature. The stiffness adjustment feature is configured to adjust the effective stiffness of the shim without affecting a preload applied to the shim.

Abstract: A user accessible shock travel spacer assembly is disclosed herein. The system is used on a shock assembly having a shaft with an initial predefined stroke length.
