RockShox Vivid Coil Ultimate RCT2 Rear Shock with Standard Bearing and Adjustable Bottom-Out

The RockShox Rear Shock Vivid Coil Ultimate RCT2 redefines the coil suspension experience with its unmatched blend of sensitivity, support, and adjustability. Designed to deliver a supple initial stroke and robust mid-stroke performance, it ensures riders feel every nuance of the terrain while maintaining control through the most demanding sections. The innovative Adjustable Bottom-Out (ABO) feature enables precise tuning of the last 20% of travel, giving riders confident end-stroke support tailored to their riding style and trail conditions.

Built to harmonize perfectly with your fork and the Charger 3.2 damper, the RCT2 damper introduces refined main-piston compression tunes that enhance mid-stroke support without sacrificing smoothness. Its wide range of Low-Speed Compression (LSC) and High-Speed Compression (HSC) adjustments allow for a dialed-in setup that’s both intuitive and effective, thanks to numbered compression settings starting at “0.” The removable rebound knob doubles as an HSC and ABO adjuster, streamlining the tuning process while offering 20 clicks of rebound control to accommodate a broad spectrum of rider weights and preferences.

This shock is engineered for today’s toughest mountain biking disciplines including enduro, E-MTB, and downhill, bringing decades of coil technology heritage into a modern performance package. With a base valve that reduces IFP forces by 40%, traction and suppleness are maximized, ensuring your bike grips and responds with precision. The optional 8×30 bearing adapter upgrade kit allows compatibility with all standard eyelets, making installation and maintenance straightforward.

Explore the full RockShox range to complement your suspension setup and enhance your ride. Whether upgrading your existing components or building a new rig, the Vivid Coil Ultimate RCT2 stands as a pinnacle of suspension engineering, designed for riders who demand consistency, reliability, and exceptional performance on every trail.
