Shock RockShox SIDLuxe IsoStrut Flight Att A2 Supercal Gen2

Flight Attendant on board

An IsoStrut for Supercaliber enhanced with SRAM Flight Attendant electronic damping technology.

The Trek Supercaliber is one of the most decorated XC race bikes on today’s World Cup circuit. Its secret sauce is IsoStrut — a structural, frame-integrated shock developed by RockShox in partnership with Trek engineers.

Pair that proven design with the latest Flight Attendant automatic suspension system, and you get a race-ready setup that adjusts on the fly and takes the thinking out of suspension management — so you can focus on speed, efficiency, and the finish line.
