A formidable 35mm chassis with the Flight Attendant system, this fork is more efficient and advanced than ever. The Charger Race Day 2 Flight Attendant electronic damper features a three-position (3P) Compression adjuster— Open, Pedal, and Lock positions.
- Algorithm that uses a suite sensors to read rider and terrain inputs to anticipate the perfect suspension position.
- Fork-only mode for hardtail bikes and customizable Auto Mode to disable "Pedal" or "Lock" positions.
- Adaptive Ride Dynamics enables the Flight Attendant system to learn from the rider to make smarter, more personalized decisions for greater efficiency and even more speed.
- DebonAir+ provides more small-bump sensitivity and tunable mid-stroke support.
- SRAM Model ID: FS-SID-UFA-D2
RockShox SID Ultimate Flight Attendant Race Day 3P Crown Fork
The RockShox SID Ultimate Flight Attendant Race Day 3P Crown Fork represents the cutting edge of cross-country suspension technology. Combining the legendary SID race chassis with SRAM’s intelligent Flight Attendant electronic suspension system, this fork automatically adjusts compression in real time to maximize speed, efficiency, and control on the trail.
At the heart of the system is the Charger Race Day Flight Attendant damper, which continuously analyzes rider input and terrain to automatically switch between Open, Pedal, and Lock modes without rider intervention. The result is a bike that climbs more efficiently, descends with greater control, and maintains momentum across constantly changing terrain.
Built around the modern SID chassis, this fork delivers exceptional stiffness-to-weight performance for competitive XC and downcountry riding. The lightweight design is paired with DebonAir+ air spring technology, improving small-bump sensitivity while maintaining strong mid-stroke support for aggressive race pacing.
The machined crown construction reduces weight while maintaining structural rigidity, and the fork uses Maxima Plush Dynamic suspension fluid to reduce friction and improve long-term durability.
Integrated with the SRAM AXS ecosystem, Flight Attendant shares the same battery system used by other AXS components and can communicate with compatible rear shocks and sensors to continuously optimize suspension performance.
For riders chasing podium finishes or simply looking for the fastest XC suspension available, the SID Ultimate Flight Attendant delivers one of the most advanced and efficient suspension systems ever developed.
