The Super Deluxe Ultimate is the most versatile shock RockShox offers, and is right at home on anything from a trail bike to a downhill bike! With a Linear XL air can, a redesigned RC2T damper, and incredibly easy setup, what&';s not to love about the new Super Deluxe D1?? All the adjustments on the RC2T damper are familiar faces, with Low Speed Compression, High Speed Compression, a firm mode switch, and an updated rebound knob right beside the piggyback to dial in your shock. Hydraulic Bottom Out is still controlling the last 20% of travel, keeping you in control when you run out of travel. All of the adjustments are incredibly intuitive, with well marked tick marks to help you get dialed in.
