RockShox BoXXer Ultimate Charger 3.2 MTB Fork with ButterWagonTech & Fender

The RockShox BoXXer Ultimate Charger 29" 3.2 D2 fork is engineered for riders who demand uncompromising performance and composure on every descent. Born from racing heritage, this fork offers a ride experience defined by predictability, control, and smoothness, ensuring you maintain speed and traction across the most challenging terrains. Featuring the innovative LinearXL air spring, it delivers a coil-like feel that remains supple at the top, supportive through the mid-stroke, and confidently controlled at the bottom thanks to its jounce bottom-out bumper.

Equipped exclusively on Ultimate models, ButterWagonTech ensures a continuous flow of oil to the bushings, significantly reducing friction and maintaining smooth, consistent performance throughout the service interval. The Charger 3.2 damper with intuitive HSC/LSC controls and ButterCups technology makes setup straightforward and communication effortless, while also reducing high-frequency trail chatter by 20%, which helps limit hand and arm fatigue. This combination of precision engineering and thoughtful features results in a fork that lets you focus on the trail and the thrill of the ride.

Designed with durability and practical use in mind, the BoXXer Ultimate includes low-grab SKF wiper seals for smoother action and longer-lasting performance, along with Maxima 920 blended 15W oil to minimize fork friction. The fork also supports bolt-on fender compatibility with full front/rear coverage, and the included BoXXer Bolt-On Fender adds an extra layer of protection. Available in striking Electric Red or Ultimate High Gloss Black finishes, this fork is as stylish as it is functional, perfectly complementing your mountain bike setup.
