RockShox SID Ultimate Race Day 2 3P DebonAir+ Boost 29" Suspension Fork
Item number: 91504
The RockShox SID Ultimate 3P 29" suspension fork with Race Day 2 damping, DebonAir+ spring and Boost dimensions for cross-country riding
The SID suspension fork from RockShox for 29" XC bikes offers 3-position compression adjustment via Crown Adjust and, in the Ultimate version, comes with lightweight Race Day 2 damping. Boost width, 120 mm travel and 35 mm stanchion tubes make it ready for every race track and down-country use. In addition to the tried and tested "Open" position for high-speed descents and "Lock" for sprints, where you need an efficient power transmission, the third "Pedal" position offers you the sweet spot in between for technical climbs where you need propulsion but also comfort. With the DebonAir+ air spring, you benefit from extreme reactivity, high traction and high tunability via air pressure. The optimised fork crown is lighter compared to the previous model without sacrificing steering precision.
