RockShox SID Ultimate Race Day 3P Fork
The RockShox SID Ultimate Race Day 3P Fork is engineered for modern cross-country racing, delivering an elite balance of low weight, stiffness, and precision handling. Built around a lightweight 35mm chassis, it reduces overall weight without compromising the rigidity needed for aggressive descents, technical climbs, and fast, high-output racing. The result is a fork that feels fast, responsive, and composed when every second matters.
At the core of the SID Ultimate is the Charger Race Day 2 damper with three-position compression adjustment: Open, Pedal, and Lock. This gives riders immediate control over suspension performance across changing terrain. The DebonAir+ spring enhances small-bump sensitivity while improving mid-stroke support for better control under load. Combined with refined bushing architecture and lightweight magnesium lowers, the SID Ultimate delivers a smooth, efficient, and race-tuned suspension feel designed for podium-level performance.

-
Charger Race Day 2 Damper - Three-position Open, Pedal, and Lock compression settings for fast on-the-fly adjustment.
