RockShox SID Ultimate Race Day 2 2P DebonAir+ Boost Remote 29" Suspension Fork

The RockShox SID Ultimate 2P Remote 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 2-position compression adjustment via remote 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. You have the choice between the two proven positions: " Open" for full damping on high-speed descents and " Lock" for sprints, where you need an efficient power transmission. 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. A matching remote is not included, so it is best to directly order it together with the shock. Please note that if you combine the suspension fork with a remote rear shock, this must also have 2-position adjustment for the remote control of both elements to work.
