SID – The XC Fork for Champions and Contenders.
Cross Country racing has never been easy, but modern trails and bikes demand suspensions that can do more than just save a few grams. The SID began to stir up the World Cup back in the 90s and is again reaching for the XC throne in the current generation. They are supported by the revised DebonAir+ suspension, new Charger damping systems and an optimized chassis.
Climbing mountains. Charge descents. In the Ultimate version, the RockShox SID is not only lighter than ever before, the impressive chassis with 35 mm stanchion diameter uncompromisingly holds the line, even when the rider is at the limit. The Charger Race Day 2 damping combines low weight with durability and allows compression adjustment in 2 positions: reliable, hard-hitting "Lock" function and plush "Open" setting. The voluminous DebonAir+ suspension, which impresses with its suppleness especially at the upper end of the suspension travel, adapts to everything, be it sporty touring or full-throttle XC use.

Pump up the volume. The SID has already made a name for itself as an XC fork that likes it a little rougher. And with the DebonAir+ suspension it is even more tunable than ever before. Whether it's a tighter setup or a more comfortable ride, the pressure adjustment makes a noticeable difference in mid-stroke support. Regardless of the setting, the smooth feel in the upper range is not lost, nor is maximum use of the suspension travel compromised. More traction, control and comfort make the SID unbeatable on any track or trail.
Stronger than ever. The current SID suspension forks not only feature longer stanchions to increase the volume of the positive and negative air spring chambers to offer virtually limitless tunability. Lengthening the stanchions also allows the upper and lower bushings to overlap completely, which means less friction and longer durability. No less impressive is the lightweight fork crown machined from aluminum. This crowning achievement ensures that the SID remains beautifully slim without compromising steering precision. The final touch is a special mixture of the well-known Maxima Plush Dynamic Suspension Lube exclusively developed for the current SID model series. Created in collaboration with the leading experts in high performance lubrication, the gold medal formula not only keeps the chassis fresher for longer, but also ensures smooth operation of internal components at all temperatures.
DebonAir+ | A key requirement to improve the suspension was additional air volume. The DebonAir+ system provides 50 % more negative volume and 16 % more positive volume, changing the spring characteristics to help each rider find the perfect setup for their riding style and current terrain. While a 10 psi reduction in air pressure benefits comfort, 10 psi more provide better support. Initial suspension travel is also noticeably smoother, thanks to a larger negative air volume and a new Top-Out spring. The steel spring is used in place of a rubber buffer and provides comfort as well as traction at the start of compression.
Maxima Plush Dynamic | The Maxima Plush Dynamic Suspension Lube is characterized by its friction-reducing effect. In addition, the lubricant convinces with properties that not only extend the durability of the fork, but also improve its performance.
