HSC Adjustment Range
The High Speed Compression (HSC) adjuster knob offers 12 clicks of adjustment and mainly affects compression damping during medium to fast suspension movements such as steep jump faces, harsh flat landings, and aggressive wash board roads.

OPTIONAL DUAL SPEED COMPRESSION (DSC) ADJUSTER
The Dual Speed Compression (DSC) adjuster provides added control and comfort tuning for on-road use while also offering more aggressive damping for use off-road. The adjuster allows for precise suspension tuning with the simple twist of two clearly defined knobs: No tools and no mess, just a way 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.
