The new RC2 damper features a new base valve with a 40% reduction in IFP forces for the most supple performance on the market, main piston compression tunes matched to the Charger 3. 2 damper for mid-stroke support, and a wide, usable range of both High Speed and Low Speed Compression adjustment without cross-talk. A numbered compression adjuster makes setup fast and easy to communicate, while 20 clicks of rebound adjustment deliver a consistent, uniform feel across a wide range of rider weights.
