The RockShox SID Ultimate Race Day is designed for cross-country racers and fast trail riders who demand the best from their front end. Combining the DebonAir air spring's class-leading sensitivity with the Charger Race Day damper's 3-position remote, it gives you precise control over the fork's character without sacrificing a gram of efficiency.

• Charger Race Day damper with 3-position handlebar remote — Open, Pedal, Locked
• DebonAir spring for exceptional small-bump sensitivity and linear feel
• 120mm travel — XC-optimised with enough travel for technical courses
• Boost 15x110mm Maxle Stealth thru-axle for lateral stiffness
• 44mm offset for stable, quick-handling 29" XC geometry
• Gloss Black with ZipTie fender included

The Charger Race Day damper is purpose-built for XC competition. Its 3-position remote gives you Open mode for full trail sensitivity, Pedal mode for reduced low-speed compression on climbs, and Locked for smooth fireroad transfers or sprinting. Switching between modes is instant and intuitive, with no need to reach down to the fork.

DebonAir is engineered to track the ground closely through rough terrain, so you carry speed rather than losing it to vibration. The large air volume and equaliser valve allow you to run lower pressures without sacrificing support — a meaningful advantage over longer XC races. Fits 29" wheels on tapered headtube Boost frames.
