Push limits on the trail with confident control from the SID Ultimate 2P fork




What Our Gearhead® Experts Are Saying:

"I’ve raced the SID Ultimate 2P on fast, technical courses and it just holds lines—super stiff for its weight. The new Race Day 2 damper feels dialed with just two modes, and the DebonAir+ spring is crazy plush off the top. It feels like it’s reading the terrain without me thinking about it."

We’re riding further, faster, and with more confidence thanks to the RockShox SID Ultimate 2P. Designed for cross-country domination, this fork is purpose-built to keep us in control on everything from punchy race laps to technical singletrack. With a new 35mm chassis that blends light weight and stiffness, SID Ultimate holds its line when we’re dancing on the edge of grip—and does it without adding grams to our build.

Inside, RockShox’s new Charger Race Day 2 damper brings ultra-reliable 2-position control with Open and Lock settings, so we can hammer climbs or dive into descents with confidence. The new DebonAir+ spring offers more small-bump sensitivity and tunability through added air volume, while Maxima Plush fluid keeps the action smooth, quiet, and consistent. Paired with remote adjustability, Boost spacing, and a modern 44mm offset, the SID Ultimate 2P is ready for flat-out XC speed on today´s most demanding courses.
