Description
ZEB Ultimate is built for the most extreme terrain—steep double-black runs, freeride features, and even the pedal back up if that’s in the cards. The Linear XL air spring delivers a coil-like ride—supple off the top, supportive through the mid-stroke, and backed by Adjustable Bottom Out (ABO) for confident end-stroke control—giving you unwavering consistency and predictability. Found only in our Ultimate forks, ButterWagonTech ensures a constant supply of oil to the bushings, reducing friction, and maintaining smooth performance throughout the entire service interval. Intuitive HSC/LSC controls on the Charger 3.2 damper with ButterCups technology make setup fast, understandable, and easy to communicate. ZEB delivers the composure riders need to confidently pick their line and hold it—no matter how extreme the trail.
