Description
Designed for demanding riders, the ROCKSHOX SUPER DELUXE ULTIMATE RC2T LINEAR XL shock combines competition performance with great ease of adjustment. Its versatile chassis adapts to a wide variety of frames and uses, from downcountry to enduro, guaranteeing efficiency and control on all terrains.
Fitted with the new LinearXL air spring, this model delivers predictable, consistent and highly adjustable behaviour thanks to volume tokens. The hydraulic bottom-out management system improves control at the end of the stroke, adding more comfort and safety in the most committed sections.
The revised RC2T cartridge allows independent adjustment of HSC and LSC compression, with intuitive ergonomics thanks to numbered dials. The new main piston, inspired by Charger 3.2 technology, delivers excellent mid-stroke support, optimising stability and traction.
Finally, the increased maximum pressure raises the overall load capacity, while the 15 rebound clicks guarantee precise and consistent adjustment. The result: a high-performing, reliable shock designed to push the limits on every ride.

Points forts
The LinearXL air spring provides a consistent and predictable feel, with adjustment possibilities thanks to easy-to-set O-ring volume spacers.
The RC2T cartridge allows independent adjustment, without interference, of low-speed compression (LSC) and high-speed compression (HSC).
The numbered compression adjustment makes tuning easier: simply start from "0" and add or remove damping.
The base valve reduces IFP forces by 40%, ensuring smoother operation while maintaining excellent traction.
The main piston compression settings are optimised to work with the Charger 3.2 cartridge, promoting mid-stroke support.
The removable rebound knob can also be used to adjust HSC.
The bottom-out bumper works in conjunction with the optional hydraulic bottom-out management system to restrict oil flow in the last 20% of travel, creating a hydraulic cushion to soften bottom-out.
Maximum pressure is increased to improve the overall load capacity of the system.
Decals are heat-applied to increase durability and preserve the product's appearance for longer.
The 15 rebound clicks provide smooth rebound curves, with a wide adjustment range allowing a consistent feel based on rider weight.
