The RockShox SID Ultimate Flight Attendant Race Day is the most advanced XC fork RockShox makes. Flight Attendant is an automatic electronic suspension system that continuously monitors terrain, rider motion, and pedalling forces, then adjusts the fork's compression mode in real time — without any rider input. You focus on racing; the fork handles itself.

  • Flight Attendant automatic suspension — continuous real-time mode adjustment
  • DebonAir spring for exceptional XC sensitivity and low-pressure tuning
  • 120mm travel for XC racing and fast trail
  • Boost 15x110mm Maxle Stealth thru-axle
  • 44mm offset, tapered alloy steerer
  • 3-position crown lever as manual override at any time
  • Gloss Black with bolt-on fender, star nut and Maxle Stealth included

Flight Attendant uses accelerometers and a gyroscope to detect the difference between bumps, climbs, sprints, and descents. On a smooth climb it locks the fork for zero energy loss. At the moment the terrain turns rough it opens the fork automatically. The system is wireless, integrates with AXS components, and can be adjusted via the RockShox app. Battery life is rated for multiple riding days between charges.

The 3-position crown lever remains available as a manual override so you can take control at any time — useful for starting blocks, transitions, or personal preference. DebonAir's large air volume and equaliser valve allow you to run lower air pressures than conventional springs for a more supple, tracking feel on XC terrain. Fits 29" wheels on Boost tapered headtube frames. Flight Attendant requires a compatible AXS battery pod, sold separately.
