SID World Cup Solo Air 100 Fork - 29in

Like a cheetah switching its tail in anticipation of a chase, the RockShox SID World Cup Solo Air 100 Fork - 29in is poised for race-day speed with stiff, snappy handling and just enough travel to soften the bumps without getting bogged down in the heavy squish of big travel front ends. Its light yet stiff tapered carbon crown and steerer tube, adjustable Charger Damper, and reinforced lower legs make this fork an ideal choice for gram-conscious XC racers who don't compromise on strength, durability, or functionality.

The SID's Solo Air spring features an easy-to-tune design with a single Schrader valve that controls air adjustment for both chambers. The feel of the spring is also customizable with RockShox's Bottomless Tokens, which alter the chamber's effective volume and compression curve to meet individual ramp-up preferences. While the Solo Air spring lets you adjust the fork for more trail-oriented terrain, the Power Bulges on the lower bushings ensure the SID is always ready to do what an XC bike is meant to do: attack and open up a gap on the climbs. Power Bulge's reinforcement also extends to terrain, helping the fork track truer across root lattices and fast descents so you can maintain the advantage you earned going up.

The fork's damper leg features the Motion Control DNA damping system, which fights off gravity with external rebound to reduce jarring and provide a controlled, smooth platform for navigation and attacking. The integrated Dual Flow technology boasts separate circuits for low- and high-speed compression as well as beginning- and end-stroke rebound damping for high-riding sensitivity over consecutive bumps and larger impacts. Pairing all this with a Rapid Recovery valve that rebounds quickly after full impacts means that the fork is always already prepped for the next hit.
