Rockshox Flight Attendant Upgrade Kit - TREK Supercaliber Gen 2

The Flight Attendant Upgrade Kits include everything you need to upgrade your rig to an automatic suspension system that listens to the rider and responds in real time.

Flight Attendant uses a suite of sensors to read rider and terrain inputs to anticipate the perfect suspension position—enabling you to ride faster, ride longer, and spend less energy adjusting your suspension and more time focusing on what matters most: the unbridled joy of riding.
