Boost your XC ambitions.

With its 32mm stanchions and the reinforcement of Power Bulge bushings, the SID RCT3 Solo Air 100 Boost Fork is already a stiff, lightweight XC missile for 29in or 27.5+ wheels. Add a Boost 110 front axle to the equation, and RockShox's recipe for world class climbing gets even stiffer. More stiffness means more efficiency, sure, but it also tracks better through terrain, so you won't lose time earned on the climbs by having to nurse your machine gently across terrain going down.

The 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 customizable in a snap with RockShox's Bottomless Tokens that adjust the chamber volume to dial in the compression curve and meet individual ramp-up preferences.

The damper leg features the Motion Control DNA damping system, which fights off gravity with external rebound to reduce jarring and provide a controlled, smooth ride across rocky trails. 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 to prep for the next hit means you can rest assured that the ride will feel smooth and in control, no matter the terrain.
