  • Patent number: 11623712
    Abstract: A mechanism and method for externally adjusting the mid-valve stiffness is described and enables adjustment of a mid-valve functionality without disassembly of a suspension system incorporating the invention. The effect of this adjustment on the damping curve is far greater than either low-speed compression adjusters or conventional high-speed compression adjusters. The apparatus combines the valve-stiffening system of a high speed compression adjuster with the sensitivity of the mid-valve. Externally accessible adjustment members are operatively coupled to the mid-valve components located internally in a fork so that manipulation of the adjustment members causes adjustment of the mid-valve and the damping force created by the mid-valve. The apparatus may be utilized in closed cartridge suspension forks (CCSF) and open cartridge suspension forks (OCSF) and other shocks or suspension dampers.
