RockShox SID Ultimate Race Day 3P Fork
Product Details
The RockShox SID Ultimate Race Day 3P Fork is purpose-built for modern cross-country racing, delivering an elite-level blend of precision, stiffness, and lightweight performance. Its updated 35mm chassis shaves even more weight while maintaining the rigidity needed to tackle aggressive descents and technical climbs. Designed with racers in mind, this fork balances speed and control, making it a top choice for XC riders who demand more from their front suspension.
At the heart of the SID Ultimate is the new Charger Race Day 2 damper, featuring a three-position compression adjustment: Open, Pedal, and Lock. This allows riders to fine-tune their performance on the fly, adapting instantly to terrain changes. The DebonAir+ spring improves small-bump sensitivity and offers tunable mid-stroke support, while the upgraded bushing package ensures a buttery-smooth feel throughout the ride. Paired with a hollow machined aluminum crown and magnesium lowers, the fork delivers race-ready responsiveness with weight savings that matter when every second counts.
