    By adding a one-piece carbon crown and steerer unit to its already exceptional XC race fork, RockShox pushes its SID XX World Cup Solo Air 120 27.5in Fork into the stratosphere of climbing speed. It's not only exponentially stiffer than the pedestrian SID XX, but it's also over 200g lighter. With a tapered carbon fiber steerer tube and crown structure, 15mm thru-axle, and carbon fiber Power Bulge providing ample durability and stiffness to tackle the fastest, most technical courses, those weight savings don't come at the cost of survivable speed. The Power Bulge bushings stiffen the chassis at the dropouts, and a user-friendly 15mm Maxle Lite quick-release thru-axle holds everything together for a solid ride every time you get on the saddle.

    The SID XX World Cup features RockShox's top end, race-ready Motion Control DNA damping system that fights off gravity with external rebound and incorporates separate circuits for low- and high-speed compression. The damping is remotely adjustable with the included Xloc remote, so you can dial it for high-riding sensitivity over consecutive bumps or larger impacts.

    The Solo Air spring is also easy to tune with a single Schrader valve, which adjusts both the negative and positive chambers at the same time, and RockShox's Bottomless Tokens, which alter the chamber's effective volume to dial in the compression curve and meet individual ramp-up preferences. Pairing all this with a Rapid Recovery valve that rebounds quickly after full impacts to prep for the next hit means you'll stay in control across rooty climbs and rocky descents.
