When a rear shock is paired into the Flight Attendant system, your suspension is able to operate in a split state. This means that while in Auto Mode, the fork and rear shock are in different suspension settings. On the fork Control Module, two suspension position LEDs can be illuminated at the same time. Split states ensures the bike is the most efficient depending on the terrain and makes your ride feel smooth and natural. Click the link in our bio to learn more about Flight Attendant. #RockShox
