Vivid Ultimate RC2T Trunnion Rear Shock - D1

RockShox Vivid Ultimate RC2T Trunnion Rear Shock - D1 is a gravity-focused air rear shock built for riders who want coil-like sensitivity with the tunability and weight advantages of an air spring. Its Linear XL air spring is designed to stay supple off the top, hold up through the mid-stroke, and stay controlled deep in the travel, making it a strong fit for modern enduro, E-MTB, and downhill bikes running higher system weights and harder impacts.

5 setup advantages that matter on real trails

1. RC2T damper with HSC/LSC adjusters - Wide, usable High Speed Compression and Low Speed Compression ranges help riders separate big-hit control from chassis support without confusing overlap
2. Adjustable Bottom Out (ABO) - Five compression settings let riders tune cushioning in the last 20% of travel for better end-stroke control on drops, compressions, and high-speed chatter
3. Linear XL air spring + “o-ring” tokens - Delivers a consistent, predictable spring feel, with quick progression changes for dialing support without resorting to excessive damping
4. 20-click rebound adjustment - Broad range with uniform rebound curves helps keep return speed consistent across rider weights and air-spring setups
5. Updated base valve / reduced IFP forces - Designed with a 40% reduction in IFP forces to improve small-bump sensitivity and traction while maintaining control under repeated impacts
6. System-matched compression tuning - Main piston compression tunes are matched in performance intent to Charger 3.2 damper characteristics for a more balanced fork/shock feel when pushing into the mid-stroke

Note: The numbered compression adjuster simplifies setup communication (start at “0” and add damping as needed), and the removable rebound knob doubles as the HSC and ABO adjuster for streamlined trail-side tuning.
