RockShox: 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.FEATURESUpgrade kits are bike brand, model, and year specificA DUB spindle required unless otherwise specifiedKits include complete fork, shock, shock hardware, pedal sensor, 2 batteries and a charger unless otherwise specifiedFlight Attendant System is completely water and dust proof to IP69KShared battery with all other SRAM AXS enabled componentsCompatible with AXS Electronic Controllers including SRAM Rocker 2 button left SPECIFICATIONSUpgrade Kit Model: ZEB
