Mountain    Suspension Forks

RockShox SID XX World Cup Fork

The Sid XX World Cup is the fork cross country racers dream about. In particular, the glossy BlackBox hollow, 1 piece UD carbon fiber crown and tapered carbon fiber steerer creates a lust factor that is off the charts. This super sexy crown and steerer is absolutely vital in providing all the stiffness you need at the weight you want. In short, the SID 29 World Cup is the complete race package that could be considered an unfair advantage.

Motion Control DNA in the Sid XX series is designed for riders looking for more cross country efficiency. The XX Motion Control DNA damper features RockShox's XLoc hydraulic remote lockout for the lightest, most ergonomic go-fast solution. The Rapid Recovery System allows the shock to recovery faster between consecutive bumps, letting the wheel track the ground with greater precision. This more active suspension system, doesn't pack up and enables the bike to ride in a higher and softer part of the spring rate. Rapid Recovery gives the rider access to more available wheel travel, bump after bump, to achieve a smoother and more controlled ride.

Solo Air lets you add air to your forks through a single Schrader valve, filling both the positive and negative air spring chambers simultaneously. So they're always in perfect equilibrium. This gives you a plush, predictable ride you can precisely tune in less than a minute with the lightest weight air spring on the market.

Other details include Magnesium, post mount disc brake with carbon Power Bulge. Other forks just increase the stanchion size adding extra weight. Power Bulge simply reinforces the lower leg to allow for an oversized bushing, increasing stiffness.
