RockShox Vivid Coil Ultimate RC2T Trunnion Rear Shock - D1 brings the traction and consistency riders expect from a modern coil rear shock, with a damper and adjuster layout built for fast, repeatable setup on enduro, e-MTB, and downhill bikes. The coil spring curve delivers a planted feel off the top and stable support through the mid-stroke, while Adjustable Bottom Out (ABO) adds controlled end-stroke tuning for confident high-speed riding and hard landings.
Dial-in control for modern long-travel bikes
RC2T damper with independent HSC/LSC - Wide, usable High Speed Compression (HSC) and Low Speed Compression (LSC) adjustment without cross-talk, making it easier to balance support, comfort, and control across varied terrain
Adjustable Bottom Out (ABO) - Five compression settings tune the last 20% of travel, helping riders add cushioning and resist harsh bottom-outs without over-stiffening the rest of the stroke
20-click rebound adjuster - Broad range with consistent rebound behavior across settings, supporting a wide spectrum of rider weights and spring rates
Updated main piston compression tunes - Designed to deliver confident mid-stroke support and align performance with forks using the Charger 3.2 damper
Numbered compression adjuster - Intuitive baseline at “0” for clear, repeatable changes that are easy to track and communicate
Lower IFP forces - Base valve design reduces IFP forces by 40% for improved small-bump sensitivity and traction while maintaining control under load
