RockShox SID SL Ultimate Flight Attendant Race Day 3P Crown 29" Suspension Fork E2

The RockShox SID SL Ultimate Flight Attendant Race Day 3P Crown 29" Suspension Fork E2 is RockShox's lightest cross-country race fork, built for racers who count every gram. A 32mm straight-wall aluminum chassis keeps weight to a minimum without giving up the stiffness needed for hard efforts out of the saddle, and the DebonAir+ air spring — tuned with increased bushing overlap and lower friction — delivers a supportive, low-friction ride over rough singletrack. Flight Attendant is what sets the SID SL Ultimate apart from a standard XC fork. The Charger Race Day 2 Flight Attendant damper automatically shifts between Open, Pedal, and Lock positions based on real-time rider and terrain input, so the fork firms up for a sprint or climb and opens back up for descents without you reaching for a lever. The system is wireless, AXS-enabled, and includes a fork-only update mode for riders running a hardtail. A machined, anodized crown gives it a clean, race-ready finish. This configuration ships with a 1.5" tapered steerer and 15x110mm BOOST axle, with travel adjustable between 100mm and 110mm, and comes in Electric Red or Gloss Black. It's built for XC racers and marathon riders who want a lightweight, automatically tuned fork, and it is not approved for e-bike use.
