RockShox SID Ultimate – the lightest 35 mm XC fork with a 3-position Race Day 2 damper

SID Ultimate is RockShox’s top-tier XC fork, created for racers seeking the lowest weight, maximum stiffness and absolute control on steep climbs and aggressive descents. The new 35 mm stanchions deliver razor-sharp handling even when riding at the limit, while the Race Day 2 damper with three compression modes lets you instantly switch between Open / Pedal / Lock. The larger-volume DebonAir+ air spring provides supple small-bump sensitivity and strong mid-stroke support, making it easy to fine-tune the fork for the demands of modern XC courses. This is pure XC performance — in an even lighter and stronger package.

Features:

• 35 mm stiff, ultra-light chassis: optimized for modern XC bikes, offering precise steering and stability on high-speed descents.
• Charger Race Day 2 damper: the lightest damper on the market; features three quick-select modes — Open, Pedal and Lock — for maximum efficiency at any moment.
• DebonAir+ air spring: plush off the top with a tunable, supportive mid-stroke—ideal for fast, technical XC riding.
• New bushing system: increased overlap improves smoothness and stiffness under lateral loads.
• Maxima Plush Dynamic fluid: reduces friction, enhances sensitivity and extends performance longevity through heavy seasons of use.
• Machined, weight-optimized crown: reduces mass while maintaining stiffness and structural integrity where it matters most.
• Bolt-in Torque Cap adapters included: allows the use of standard hub end caps without requiring special wheels.
