Conquer mountains. Navigate descents with confidence. The SID Ultimate is unlike other XC suspension forks. It is lighter than ever before and features an impressive 35mm chassis that holds its line when you're pushing the limits. The new Race Day 2 damping system includes a three-position compression adjustment (3P) - from the rigid "Lock" setting to the comfortable "Open" and the efficient "Pedal" mode. Thanks to a new, more voluminous DebonAir+ spring that is smooth at the top of its travel, the SID adapts to everything from full-throttle cross-country to sporty touring, offering plenty of adjustment options.
