The FOX Dual Speed Compression (DSC) adjuster provides added control and comfort tuning for lower speed cruising, all the way to aggressive damping for high speed whoops and carving dunes. The adjuster allows for precise suspension tuning with the simple twist of two clearly defined knobs, using simple tools to easily fine - tune your suspension to best suit your needs in any conditions. The DSC increases both low and high - speed compression levels up to 25, allowing you to maximize small - bump compliance and traction while still having the extra damping required for big hits.
