RockShox ZEB Ultimate B1 27.5" Boost fork

The RockShox ZEB fork is built for the most extreme terrain – steep, double black descents and freeride trails. The all-new LinearXL air spring provides a coil-spring-like ride – responsive at the start of the stroke, with mid-stroke support and Adjustable Bottom Out (ABO) support for ultimate control at the end of the stroke. This ensures a consistent and predictable driving feel. ButterWagonTech technology, exclusive to Ultimate forks, guarantees a continuous supply of oil to the bushings, effectively reducing friction and maintaining smooth performance throughout the entire service interval. The intuitive high-speed and low-speed compression (HSC/LSC) controls on the Charger 3.2 with ButterCups technology allow for quick and easy adjustments. ZEB provides riders with the stability and confidence needed to precisely choose and maintain a track, regardless of the terrain.
