Maximum XC performance. Minimum weight.

Do you want to save every last gram and take the performance of your XC bike to the next level? The SID SL Ultimate is made for just that. With the intelligent Flight Attendant technology, the fork automatically adapts to the terrain in a fraction of a second - for maximum efficiency and optimum traction on any trail. Its lightweight, race-ready construction is made for the most demanding XC trails in the world and gives you the decisive advantage from the start to be at the front of the pack.
The optimized DebonAir+ air spring and a larger overlap of the bushings reduce friction and breakaway torque, ensuring a sensitive response. The milled and anodized crown is stiff, looks classy and also reduces the weight. Last but not least, the tire clearance has also been optimized so that you have a free choice of width.

The SID SL Ultimate is more than just light - it is smart, individual and uncompromisingly designed for speed. Perfect for ambitious XC racers who want to make the decisive difference at the start line.

Charger Race Day Flight Attendant
The electronically controlled shock has a 3-position compression stage, which can be adjusted from completely open via the pedal to a rock-solid lockout. An adjustable rebound stage rounds off the package perfectly.

The simplicity of riding
The completely new algorithm uses special sensors to detect the current condition of the ground and your individual riding situation. No other suspension system offers you more personalization options.

Launch Control
This function gives you the perfect start to your race. Your suspension is locked for a period of time defined by you and then automatically switches to auto mode when it detects larger bumps.

Fork-only update
Hardtail riders can now also enjoy the Flight Attendant System. It also works without dampers and is designed to optimize the balance between efficiency and comfort.

Customizable auto mode
With the "Pedal Disabled" option in your SRAM AXS app, riders can switch off the pedal mode. This allows you to choose between the Open and Lock position - ideal for trail or enduro riders who prefer consistent traction.

Adaptive Ride Dynamics
Adaptive Ride Dynamics enables the Flight Attendant System to adapt to your riding style and make individual decisions that make your tour faster and more efficient.

Compatibility
The Flight Attendant system is compatible with all AXS components. The more of them there are on the bike, the better everything works together. The batteries of all components are compatible with each other.

32 mm chassis
Slim, light and stiff for precise handling. Developed for the racetracks of the world, it is ready to take you to the podium.

Milled crown
Fork crown machined to perfection for low weight, high stiffness and unparalleled stability.

Optimized bushing package
Thanks to reduced friction and maximized bushing overlap, the fork responds more sensitively than ever before. This gives you perfect control on the trail and gets you to the finish line faster.

Reduces friction and wear and optimizes performance on every ride.

Bottomless Tokens
