Climb mountains. Charge descents. SID Ultimate Flight Attendant isn’t like other XC forks, featuring a formidable 35mm chassis that holds the line when you’re on the edge. With the Flight Attendant system, this fork is more efficient and advanced
than ever before. The new Charger Race Day 2 Flight Attendant electronic damper features a three-position (3P) Compression adjuster— Open, Pedal, and Lock positions, all at your fingertips. SID Ultimate Flight Attendant adapts to everything from fullgas cross-country to sporty backcountry loops thanks to a new, higher-volume DebonAir+ spring that’s supple at the top of its travel with tons of tunability.
