ZEB Ultimate is engineered for riders pushing into the most demanding terrain, from steep double-black descents to aggressive freeride lines. Built around a stiff 38 mm chassis, it delivers the stability and front-end precision required to stay composed through high-speed impacts and rough trails while remaining capable for long days in the mountains.

The LinearXL air spring produces a coil-like feel with a supple initial stroke and strong mid-stroke support, while Adjustable Bottom Out (ABO) allows riders to tune end-stroke progression for confident control on heavy hits. Exclusive to Ultimate models, ButterWagonTech ensures a constant supply of oil to the bushings, reducing friction and maintaining smooth suspension performance throughout the service interval. The Charger 3.2 RC2 damper with ButterCups technology adds independent high- and low-speed compression adjustment while reducing high-frequency trail vibration, delivering precise control and improved rider comfort.
