RockShox SID SL Ultimate Race Day 3P 29" Boost suspension fork

The new RockShox SID SL Ultimate fork is designed for ambitious XC racers who want to reduce the weight of their bike without compromising on performance. The DebonAir+ air spring provides a smooth ride and better mid-stroke support, while a new generation of seals minimizes friction.

The precision-milled anodized crown not only saves grams, but also stands out visually – especially in the iconic Electric Red finish. The fork has more bushing overlap and space for wider tires (up to 62 mm), which allows for better grip and confidence in technical passages.

The key element is the Charger Race Day 2 (3P) damping system with three clearly separated modes – Open / Pedal / Lock – which allow for precise tuning of the fork stiffness according to the climb, flat or descent. Weighing just 1,390g (for 110mm travel), it is one of the lightest XC forks on the market and is ideal for world-class racing.
