The RockShox Flight Attendant ZEB 29 Upgrade Kit for TREK Slash 2021–2022 brings cutting-edge, electronically controlled suspension performance to your enduro bike. Designed specifically to integrate with compatible Trek Slash frames and RockShox ZEB 29 forks, this kit allows you to experience the benefits of RockShox’s Flight Attendant system, which automatically adjusts suspension settings in real time. By constantly reading the terrain and your riding inputs, it helps you stay in the optimal mode for climbing, pedaling on flats, and descending, without needing to reach for any levers.
This upgrade kit is ideal for riders who want to maximize efficiency on long climbs while still enjoying full, plush performance on aggressive descents. It is tailored to modern enduro and all-mountain riding, where quick transitions between technical uphills and rough downhills are the norm. With cleaner cockpit control and smart integration, the Flight Attendant system helps you focus on line choice and speed, rather than suspension adjustments. If you own a compatible Trek Slash and ZEB 29 fork, this kit is a premium way to modernize your suspension and unlock the full potential of your bike.
