Vivid Ultimate DH RC2 Trunnion Rear Shock - D1

RockShox Vivid Ultimate DH RC2 Trunnion Rear Shock - D1 is a gravity-focused air rear shock built for riders who want coil-like sensitivity with the tuning range and consistency of a modern DH damper. The LinearXL air spring is designed to stay supple off the top while holding support through the mid-stroke, and the Adjustable Bottom Out (ABO) adds a dedicated control for the final portion of travel—helpful for hard landings, high-speed compressions, and bike-park impacts without making the whole stroke feel harsh.

The RC2 damper targets clear, repeatable setup with independent High-Speed Compression (HSC) and Low-Speed Compression (LSC) adjustment, plus a wide-range rebound circuit for matching different rider weights and leverage curves. Built as a system-driven option for downhill bikes, it’s a strong choice for riders pairing with a RockShox BoXXer front end and prioritizing traction, composure, and end-stroke control on steep, fast terrain.

Dial-in advantages for downhill setup

1. RC2 Compression Tuning (HSC/LSC) - Wide, usable adjustment range with minimal cross-talk, making it easier to separate support for pumping/braking from control on square-edge hits
2. Adjustable Bottom Out (5 settings) - Fine-tunes the cushioning in the last 20% of travel for better big-hit control without over-stiffening the early stroke
3. LinearXL Air Spring + Bottomless Tokens - Predictable spring curve with simple progression changes, helping riders tune for traction, pop, or added ramp based on track demands
4. 20-Click Rebound Range - Broad, consistent rebound adjustment to match rider weight, spring setup, and rebound speed preferences
5. Updated Internal Architecture - New base valve design with a claimed 40% reduction in IFP forces to improve small-bump sensitivity while maintaining control under repeated DH impacts
6. Numbered, Tool-Free Style Adjuster Design - Numbered compression adjuster for repeatable changes, plus a removable rebound knob that doubles as the HSC and ABO adjuster for simplified trailside tuning
