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.
