ROCKSHOX rear shock SIDLuxe Ultimate Flight Attendant Standard Mount 185x50 mm | Trek TopFuel Gen 3-4
Climb mountains quickly. Master descents with speed.
The SIDLuxe Ultimate Flight Attendant is the fastest, most efficient and most technically advanced shock that RockShox has ever brought to market. Depending on the current riding situation, its intelligent algorithm always selects the right setting between the three compression positions "open - pedal - lock" and makes every ride a special experience.
With the SIDLuxe Ultimate Flight Attendant, you are equipped for everything - from a fast XC race to an extended back-country tour to relax. Your path to the podium has never been so clear.
The simplicity of riding
The completely new algorithm uses special sensors to detect the current surface conditions and your individual riding situation. No other suspension system offers you more personalization options.
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.
Solo Air
The negative and positive air chambers are filled simultaneously using just one valve, which makes it much easier to adjust your personal set-up.
Counter Measure
Thanks to the Counter Measure technology, the breakaway torque of your shock is practically reduced to 0. This means that even small bumps are absorbed and you always have perfect traction.
SAG Gradients
If you don't set your suspension elements correctly, you might as well be riding someone else's bike. With RockShox, the markings for the exact adjustment of your suspension components are printed directly on them, saving you a lot of time when setting them up.
Maxima Plush Damping Fluid
The best suspension needs the best oil. Maxima Plush is designed to reduce wear on the suspension elements, friction and noise.
Ultimate Flight Attendant damper
The Ultimate Flight Attendant shock allows you to adjust the rebound to your needs. It also has a lockout that automatically selects the right setting in three positions (open/pedal/lock).
The shock must be used in conjunction with a Flight Attendant fork and a pedal sensor or power meter. The Flight Attendant system cannot function without these components. The shock is matched to the respective model and is only 100% suitable for this model!
