The patented PLUSHPORT system generates the specific compression damping in every stroke, to get small bump sensitivity, mid-stroke support and bottom-out control. To do so, an opening in the low-speed compression circuit (the PLUSHPORT) is slowly closed by a floating piston when the fork goes into its travel, at the beginning of the stroke, it is fully opened to offer maximal traction.
Once the fork compresses, this port is slowly closed which leads to higher compression damping, enabling more support from the fork. For the last centimeters of travel, the piston keep the PLUSHPORT closed. This forces most of the oil which is still being displaced by the compression piston to move through the high-speed circuit, creating much higher compression damping force for a bottomless feel.
