Y en pocas palabras...
"The Cone Valve fork is a very high-end system that uses quality components and a unique “cone valve” mid-valve to control compression damping. This cup-and-cone system is different from the shim system used in nearly every fork on current dirt bikes. The cone meets the ports of the rebound piston and is backed by a coil spring. This allows for variable orifice functions. The design has advantages over the normal shim-stack mid-valve. It reduces turbulence and cavitation, since there are no sharp edges or abrupt corners in the path of the fluid flow. It allows for infinite tuning via three different cones and various mid-valve springs. The highest-quality materials, super-tight tolerances and high-end coatings equate to less friction."
