SID SL Ultimate Flight Attendant 29in Boost Fork

What Our Gearhead® Experts Are Saying:

"This fork blew my mind. It’s the lightest XC fork I’ve ridden, but it still tracks with pinpoint precision. The Flight Attendant system auto-adjusts faster than I ever could manually—it just knows when to open up or firm up. On race days or long epics, it saves my legs and keeps me focused on speed."

We're chasing podiums, PRs, and smoother lines—and the RockShox SID SL Ultimate Flight Attendant fork brings intelligent performance that meets our pace. With wireless control that thinks faster than we do, the Flight Attendant system automatically adapts compression settings on the fly. We get maximum power transfer on climbs and supple support on descents without flipping a switch or losing momentum.

Built for pure XC speed, the SID SL Ultimate Flight Attendant features 100mm or 110mm of travel, a 32mm lightweight chassis, and SRAM’s lightest DebonAir+ spring. The Charger Race Day 2 Flight Attendant damper delivers electronically controlled 3-position compression, customizable via Auto Mode. A machined, anodized crown adds stiffness and style, while bushing overlap and Fast Black stanchions reduce friction. It’s the smartest, most race-tuned fork we’ve ever ridden—and it never stops thinking about how to go faster.
