Climb mountains. Charge descents. The RockShox SID Ultimate isn’t like other XC forks. It is lighter than ever with a formidable 35mm chassis that holds the line when you’re on the edge. The Race Day 2 damper provides efficient Pedal positions, all at your fingertips. SID Ultimate adapts to everything from full-gas cross-country to sporty backcountry loops thanks to a new, higher-volume DebonAir+ spring that’s supple at the top of its travel with tons of tunability.
- 35mm chassis is the perfect blend of light weight and rigidity for the modern XC bike
- Charger Race Day 2 3P damper is one of the lightest damper on the market and features three compression positions: Open, Pedal, or a rock-solid Lock
- DebonAir+ provides more small-bump sensitivity and tunable mid-stroke support
- Bushing package maximizes bushing overlap for a smooth, solid ride
- Maxima Plush Dynamic Suspension Lube reduces friction, lasts longer, and enhances suspension performance ride after ride
- Crown machined to shave weight without compromising strength and stiffness
- Bolt-in torque cap adapters included for use with standard hub end-caps
