The RockShox SID SL Ultimate Race Day 29 3P is purpose-built for riders who demand maximum speed and efficiency on cross-country courses. Designed around 29-inch wheels and ultra-light construction, this fork is a favorite choice for racers who want precise steering, responsive suspension, and minimal weight on the front of their bike. The SID SL platform is known for its stiff yet lightweight chassis, helping you hold your line through technical sections while still climbing and accelerating with ease.
Equipped with RockShox’s high-end Race Day damper and a 3-position (3P) remote or crown-adjustable compression system, this fork allows you to quickly switch between open, pedal, and firm modes to match changing terrain. This means you can sprint out of the saddle, attack climbs, or charge descents with confidence and control. With modern XC tuning, smooth air spring performance, and refined small-bump sensitivity, the RockShox SID SL Ultimate Race Day 29 3P delivers the speed-focused performance serious cross-country riders and racers expect from a top-tier suspension fork.
