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.
