Super Deluxe Ultimate RC2T Rear Shock - Standard Trunnion, D1

RockShox Super Deluxe Ultimate RC2T Rear Shock (Standard Trunnion, D1) combines race-proven control with an air-spring and damper package designed to be easy to tune across a wide range of trail, enduro, and downcountry frames. The Linear XL air spring delivers a consistent, predictable spring curve and straightforward progression tuning, while the updated RC2T damper adds clear, independent compression adjustments and strong mid-stroke support for riders who want traction without giving up chassis stability.

Key performance advantages for real-world setup and control

1. Redesigned RC2T damper with HSC/LSC - Provides a wide, usable range of High Speed Compression and Low Speed Compression adjustment with minimal cross-talk, making it easier to dial support for pumping and cornering without over-stiffening on impacts
2. Charger 3.2-matched compression tune - Updated main piston compression tuning targets supportive, controlled mid-stroke behavior for better ride height and consistency when trails get steeper or faster
3. Linear XL air spring with o-ring tokens - Maintains a predictable feel through the travel, with quick progression changes via easy-to-adjust volume tokens for dialing pop vs. bottom-out resistance
4. Updated bottom-out system - New Jounce Bottom Out bumper with optional Hydraulic Bottom Out adds end-stroke control by restricting oil flow in the last 20% of travel, reducing harsh bottom-outs under hard compressions
5. 15-click rebound adjustment - Broad, uniform rebound range helps match return speed to rider weight and spring pressure for traction and stability over repeated hits
6. Higher max PSI + lower IFP forces - Increased maximum air pressure supports higher system weights, while a new base valve designed to reduce IFP forces helps improve small-bump compliance and sustained traction

The Standard Trunnion mount format fits modern frame designs that package the shock for stiffness and clearance, making this a high-end upgrade option for riders prioritizing tunability, mid-stroke support, and controlled end-stroke behavior in a premium RockShox air rear shock.
