ROCKSHOX suspension fork 29" SID Ultimate Flight Attendant Race Day 3-P Crown DebonAir+ 120 mm BOOST 44 mm Offset tapered red | USB-C Charger
Climb mountains quickly. Master descents with speed.
The SID Ultimate Flight Attendant is not like other XC forks. It has been designed around a stiff yet lightweight 35 mm chassis. Suspension is provided by the DebonAir+ air spring, which offers you maximum sensitivity with the smallest bumps and great support in the mid-travel range.
With the Flight Attendant system, your fork is more efficient and advanced than ever before. The new electronic Charger Race Day 2 Flight Attendant shock features a 3-position (3P) compression adjuster - open, pedal and lock - all at the touch of a button.
With the SID Ultimate Flight Attendant you are equipped for everything - from a fast XC race to an extended back-country tour to relax.
Electric Red
Red embodies the speed, power and intensity typical of racing. Since 1989, red has been a defining and ever-present color in the RockShox catalog. From now on, the same red extends across all suspension forks and shocks in the RockShox Signature series.
Charger Race Day 2 Flight Attendant
The electronically controlled damper has a 3-position compression stage, which can be regulated from completely open via 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.
35 mm chassis
Perfect balance of stability, stiffness and low weight. Optimized to meet the requirements of modern XC bikes.
Milled crown
Fork crown milled 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.
Maxima Plush Dynamic Suspension Lube
Reduces friction and wear and optimizes performance on every ride.
DebonAir+
The DebonAir+ technology has an extremely low breakaway torque in order to work as sensitively as possible from the very beginning with the smallest bumps. It offers you perfect performance in the mid-travel range and reliably prevents bottoming out with high end progression.
Bottomless Tokens
Enables individual adjustment of the air chamber size. This allows you to perfectly match the spring characteristics of your fork to your riding style.
Maxle Stealth
Very lightweight thru axle which can be fitted and removed with a 6 mm hexagon socket. In addition to a clean look, it also saves some weight on the unsprung mass.
Bolt-in torque caps
Torque caps reinforce the connection between the hub and the fork dropout with an enlarged surface that connects the two. This creates a stronger and stiffer interface that gives you better feedback and more control. So you can concentrate on the most important connection: The one between your bike and the trail. Thanks to screw-in torque cap adapters, nothing stands in the way of using normal hub end caps.
