RockShox ZEB Ultimate 29" MTB Fork with Charger 3.2 RC2 Damper and LinearXL Spring

The RockShox ZEB Ultimate CHARGER 3.2 B1 29" fork redefines performance for riders who demand the utmost from their mountain bike suspension. Designed to tackle the most challenging terrain—from steep double-black diamond descents to technical freeride paths—this fork combines strength, precision, and responsiveness. Its robust 38 mm chassis provides unparalleled stiffness, ensuring that your front end remains stable and controlled even during high-speed impacts and rough trails. Whether you’re enduring grueling all-day rides or conquering aggressive lines, the ZEB Ultimate is engineered to keep you composed and confident.

At the heart of the ZEB Ultimate lies the innovative LinearXL air spring, which mimics the feel of a coil spring by offering a supple initial stroke combined with strong mid-stroke support. This creates a smooth, controlled ride that balances comfort and performance. Riders can fine-tune their experience further with the Adjustable Bottom Out (ABO) feature, allowing precise control of end-stroke progression for confidence on heavy hits. Exclusive to the Ultimate model, ButterWagonTech continuously lubricates the bushings, reducing friction and ensuring consistent, smooth suspension throughout long service intervals.

The Charger 3.2 RC2 damper, enhanced with ButterCups technology, provides independent high- and low-speed compression adjustments to tailor the fork's response to your riding style and terrain. It also reduces high-frequency trail vibrations, minimizing fatigue and boosting rider comfort on extended rides. Complemented by SKF low-friction wiper seals and Maxima 920 suspension fluid, the ZEB Ultimate delivers durability and smoothness that elevate every trail adventure. With integrated short fender mounts and a choice of striking Electric Red or Gloss Black finishes, this fork not only performs flawlessly but looks the part.
