With over 20 years of refinement, SR Suntour’s Cartridge Science Program has created the most controlled, consistent and functional dampers we’ve ever produced. PCS is a simple and repeatable way of reducing cavitation (air and oil mixing and creating pressure). Less cavitation means more predictable damping performance, and with cartridges being tested to over 200,000 cycles that performance should last run after run, ride after ride. When it does need servicing, our Quick Service Product (QSP) Philosophy, ensures that you’ll spend less time in the work stand and more time on the trail.

3CR PCS
With easy 3-position compression adjustment you can go from open to mid to firm at the touch of a lever. Backed with our PCS system to reduce cavitation you can instantly tune your ride to the terrain.
Open: Supportive but ready for big hits, varying terrain and downhills
Mid: Extra support for hard charging and undulating terrain
Firm: Efficient pedaling for roads, smooth climbing and big sprints

2CR PCS
Take all the guesswork out of your suspension with easy 2 position on-the-fly adjustment. Whether you choose the fully open position to tame the terrain or the firm position for the utmost in pedaling efficiency the 2CR PCS cartridge has you covered.
