The RockShox SIDLuxe Ultimate is the matching rear shock for the SID fork family, designed to deliver a lightweight, sensitive, and fully adjustable platform for XC race and fast trail full-suspension bikes. The 210x50mm stroke covers a range of XC frame platforms, and the 3-position lever with an 8-click adjustable mid-mode gives you meaningful compression versatility on the trail.

• SoloAir spring with 1 token for a light, active feel
• 85-click rebound and 30-click compression adjust for fine-grained tuning
• 3-position lever: Open, adjustable Mid-mode (8 clicks), and Lockout
• Adjustable lockout threshold (8 clicks) — set how firm a hit is needed to blow through the lockout
• Standard/Standard mount, blue decal included

The 3-position lever is the centrepiece of the SIDLuxe Ultimate's on-trail versatility. Open delivers full sensitivity for rough descents. Mid-mode provides a user-defined level of compression firmness — ideal for flat-out cross-country pedalling or rolling trail where you want efficiency without sacrificing all the suspension. Lockout closes the damper to near-rigid for smooth surface riding. The lockout's adjustable threshold means you can dial in exactly how much force is needed to overcome the lockout on a big hit, preventing the shock from topping out on rough descents when left accidentally locked.

SoloAir is a lightweight spring system that uses a single Schrader valve for easy pressure adjustment, making setup quick and accessible. The included 1 bottom token allows you to tune end-travel ramp if needed. Standard/Standard mount fits a wide range of XC full-suspension frames — confirm your frame's eye-to-eye measurement is 210mm and stroke is 50mm before ordering.
