In 1998, Rock Shox launched the first Sid suspension fork on the market. Since then, it has been the epitome of a cross-country suspension fork and has served as a reference for products from other brands. For two years now, the RS-1 has been the first choice for cross-country racers. Although an absolute top fork, it is somewhat heavier than the old Sid and wheel installation is a little fiddly due to the movable ends of the upside-down fork. It soon became clear that the Sid would once again be the first choice for cross-country racers, and this is confirmed with the new Sid.

The Sid is available in the World Cup, RLC, XX and RL versions. All of these are available for 27.5 and 29-inch wheels as 100 or 110 millimeter boost versions as well as 27.5 plus boost. All versions are also available as Solo Air versions. Compared to the old Sid forks, the new ones have a slightly more linear spring characteristic. However, this can now be adjusted to your own requirements with so-called bottomless tokens, plugs with which the air volume is reduced.

Lower weight and better performance

The Rock Shox engineers have paid particular attention to low weight, precision, performance and speed. From its special 100 millimeter travel chassis, damping and air spring to its precise steering characteristics and meticulous elimination of excess weight, every design element of the Sid is built for peak race performance.
The particular focus of the SID World Cup is on cross-country performance. The chassis and inner workings are specially designed for a suspension travel of 100 millimeters. The SID is now equipped with Rock Shox's "Charger Damper™" - ideal for riders who prefer a harder ride. The damper allows the rebound, lockout and low-speed compression to be adjusted.

The top-of-the-range "World Cup" model is the only one with a carbon steerer tube and crown. With a stated weight of 1,366 grams, the Sid now weighs practically the same as the top model from Fox. Similar to the latter, the Sid also comes with a bolt-on axle (Maxle Stealth) without a quick-release lever.
The same weight-reduced axle can also be found on the other Sid models. Incidentally, these do not come with carbon steerer and crown, but aluminum ones. However, at 1530, 1572 and 1523, the RLC, XX and RL versions are still within the lightweight range.

Rock Shox also gives the Sid more stiffness through the combination of wheel end caps and larger contact surfaces on the fork. This stiffer combination allows for more precise steering and incredibly accurate steering.
