Super Deluxe Ultimate is a race-proven, award-winning rear shock that keeps improving. Its high-flow main piston reduces High-Speed Compression damping, eliminating hang-ups and allowing the wheel to easily get out of the way on hard impacts. RC2T damper offers Rebound adjustment, independent High and Low-Speed Compression adjustment, and an easy-adjust Threshold lever for added pedaling efficiency. DebonAir+ air springs maximize fine-tuning potential, allowing you to tune your air volume with Bottomless Tokens to match your bike, desired ride feel perfectly, and the trail ahead. Hydraulic bottom-out kicks in to restrict oil flow within the last 20% of travel, offering a soft hydraulic cushion that reduces harsh bottom-out.
