RockShox SIDLuxe Isostrut Ultimate Flight Attendant Rear Shock for Trek Supercaliber

The RockShox Rear Shock SIDLuxe Isostrut Ultimate Flight Attendant represents a significant advancement in suspension technology, engineered exclusively for the Trek Supercaliber 20. This rear shock integrates seamlessly within the frame, delivering 80mm of finely tunable rear suspension travel that expertly balances stiffness and support while minimising friction. Featuring a robust 38mm strut tube, it ensures exceptional durability and responsiveness, essential for high-performance cross-country (XC) racing and demanding trail conditions.

What distinguishes this shock is the innovative Flight Attendant automatic suspension system. Employing a sophisticated algorithm combined with an array of sensors, it dynamically adjusts suspension settings in real time to suit your riding style, terrain variations, and physical input. This system offers three distinct damping modes—Open, Pedal, and Lock compression—allowing the bike to adapt intelligently for optimal efficiency and speed. The inclusion of an intuitive rebound dial and Maxima Plush Dynamic Suspension Lube further enhances both performance and longevity, ensuring a smooth, controlled ride throughout your journey.

Designed to integrate flawlessly with the SRAM AXS ecosystem, the Flight Attendant system is cable-free and shares its battery with other AXS-enabled components, providing a streamlined and unobtrusive setup. Its IPX7 waterproof rating guarantees reliability under adverse weather conditions, making it a dependable choice for competitive World Cup racing or challenging trail rides. For those seeking precision and control in a rear shock, this product elevates the performance of your bike to new standards.
