RockShox SIDLuxe Ultimate IsoStrut Flight Attendant Rear Shock 239 x 40mm SoloAir

The IsoStrut Flight Attendant shock for the Trek Supercaliber, for racers who'd like the bike to do the hard thinking.

IsoStrut is the structural, frame-integrated shock RockShox created with Trek's engineers, and it's the magic behind one of the most decorated XC race bikes on the World Cup circuit. Add Flight Attendant's automatic damping and you get a race-ready package that moves between Open, Pedal and Lock as its sensors read you and the terrain.

You get 80mm of tunable rear suspension with a 38mm strut tube for added stiffness and support, and a fully checked compression circuit tuned to eliminate pedalling bob. A numbered rebound dial shows your exact setting at a glance.
