Race-focused Rudy XL Ultimate fork offers efficient damping for high-speed gravel
What Our Gearhead® Experts Are Saying:
"This fork changed how I ride gravel. It adds just enough travel to keep me composed on washboard or techy descents, but it still locks out fully for road sections. The 60mm version is my go-to for bikepacking, while the 50mm gives my race bike a fast, light feel."
Designed for riders pushing the boundaries of drop-bar terrain, the SRAM Rudy XL Ultimate offers refined control, confidence, and comfort for gravel and mixed-surface conditions. Available in 50mm or 60mm travel options and tuned specifically for 700c wheels, this fork provides a balanced blend of small-bump sensitivity and high-speed support without compromising weight or efficiency. The 45mm offset keeps handling quick and stable whether you’re descending chunky doubletrack or threading through tight urban corners.
Internally, the Rudy XL Ultimate features the Charger Race Day 2 damper—a lightweight, race-proven system with two-position compression adjustment (Open/Lock) for rapid adaptation to changing terrain. Partnered with SRAM’s Solo Air spring, it offers consistent pressure balance across travel, making for smooth actuation and excellent mid-stroke support. Its 30mm aluminum stanchions are coated in a low-friction Fast Black finish and paired with a forged hollow aluminum crown and magnesium lowers for a precise, lightweight platform.
Flat-mount disc brake compatibility, 12x100mm thru-axle spacing, and integrated short-fender mounts make the Rudy XL Ultimate ready for any high-performance gravel build. Whether climbing in a gravel race, floating down a loaded bikepacking route, or tucking into a smooth tarmac descent, this fork stays composed and responsive across all surfaces.
