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. And with Flight Attendant on board, ZEB Ultimate is unrivaled—its improved algorithm personalizes every adjustment to your preferences, terrain, and effort, so you can charge without hesitation. 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.
