The RockShox BoXXer Ultimate is an uncompromising downhill suspension fork designed for maximum control on the most demanding trails. Developed for steep, fast, and technical descents, it combines high stiffness with responsive damping while reducing hand fatigue. With its revised Charger 2.1 damping, DebonAir air spring, and low-friction SKF gaskets, the BoXXer delivers a precise ride feel, high traction, and enormous reserves for tough bike park and race conditions.
Charger™ 2.1 Damping
The redesigned damping system is engineered to minimize unwanted friction while improving control and comfort during fast, rough descents. High- and low-speed compression settings are available.
DebonAir™ Air Spring
The air chamber delivers exceptionally sensitive suspension response and provides a spring-like feel throughout the entire travel—for more grip and stability on technical downhill trails.
SKF Low-Friction Gaskets
Low-friction SKF seals improve suspension response while increasing the fork’s durability during intensive use.
Redesigned Chassis
The BoXXer features a completely redesigned casting with an optimized bridge design, an improved cable mount, and modern geometry tailored for today’s downhill bicycles.
Volume Spacers
By using tokens (volume spacers), the air volume in the fork can be reduced, thereby influencing the spring rate curve. This results in smoother response with higher end progression.
Maxle Stealth
The Maxle Stealth thru axle is a lightweight, slim alternative to Maxle Lite and Maxle Ultimate.
