RockShox's SID XX World Cup simply dominates the XC world. Its impressively low weight is achieved with a hollow, 1-piece carbon crown and steerer, with stiff magnesium lowers for a dominant, commanding ride. Tune your ride to perfection with the fully adjustable XX Motion Control DNA damping, Dual Flow rebound, and the Solo Air spring that keeps both your positive and negative air chambers in equilibrium. Complete with RockShox's XLoc hydraulic remote lockout, the SID XX World Cup is a precision tool that lets you drop the hammer and leave everyone wondering how to keep up.
