Overview

ZEB 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 all-new LinearXL 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. Found only in 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 and easy to communicate.
