Climb mountains. Conquer descents with confidence. The SID Ultimate is not like other XC forks. It is lighter than ever before and features an impressive 35mm chassis that holds the line when you're pushing your limits. The new Race Day 2 damping includes a three-position compression adjustment - from the rigid "Lock" to the comfortable "Open" and the efficient "Pedal" setting. The SID adapts to everything from full-throttle cross-country to sporty tours, thanks to a new, more voluminous DebonAir+ spring that is smooth at the top of the travel, offering plenty of adjustment options.
