The RockShox ZEB Ultimate fork is designed for the most extreme terrain, from double black runs to freeride, and even for hiking back up if that’s part of the plan. The Linear XL air spring offers a feel similar to coil springs: soft at the beginning of the stroke, supportive in the middle, and a damped bottom-out with adjustable bottom-out stop for greater control, in a configuration designed to deliver flawless consistency and predictability. Available exclusively on Ultimate series forks, ButterWagonTech technology ensures a continuous supply of oil to the bushings to reduce friction and maintain smooth, consistent performance between service intervals. On the Charger 3.2 cartridge, featuring ButterCups technology, intuitive high- and low-speed compression control makes the setup quick and easy to understand and communicate. The ZEB fork offers the control every rider needs to choose their line and hold it with confidence, even on the most extreme terrain.

- The Linear XL air spring provides a consistent and predictable feel, combined with adjustable bottom-out (ABO) for greater control at the end of the stroke.
- ButterWagonTech technology ensures a continuous supply of oil to the bushings to reduce friction and maintain smooth, consistent performance between maintenance intervals.
