RockShox ZEB Ultimate Flight Attendant 29 fork with upgraded Charger 3.2 damper
What Our Gearhead® Experts Are Saying:
"The new Charger 3.2 damper runs Flight Attendant automatically based on terrain and rider input, so the fork is open when the trail demands sensitivity and firm when it demands control. This generation also adds Adjustable Bottom Out, which lets me dial end-stroke feel independently of token count and gives me one more variable to tune without touching the air volume."
Why We Like It
ButterCups sit at both the damper and air spring shafts, intercepting high-frequency trail chatter before it transmits into our hands. The new ButterWagonTech runs continuous oil supply to the bushings throughout the service interval, keeping friction consistent rather than letting it creep up between services. Both features are exclusive to the Ultimate.
