FUNDAMENTALLY FASTER

The all-new BoXXer is what happens when the paradigm shifts and the primary focus is improved rider composure. When you isolate and eliminate variance and surprise, precision goes up, fatigue goes down, and speed and traction increase as by-products. Predictability is fundamental. BoXXer gets it. Riding BoXXer proves it.

COMPOSURE = SPEED


Nothing amplifies rider performance more than composure. By putting our focus on improving rider posture, vision, and energy preservation, speed comes naturally. We did it by re-designing BoXXer to better isolate impact and vibration—but still allow feel for bike and terrain inputs. For racers to go faster.

DESIGN EVERYTHING TO ENABLE THE AIR SPRING


Damper performance has defined the conversation in mountain biking, but without the best air spring, the best damper isn’t. LinearXL is a whole fork approach to air spring design, reducing the speed-sensitivity of the air spring—delivering predictable position-sensitive control.

SETUP SHOULD BE SIMPLE


The perfect setup is personal. But you shouldn’t have to “puzzle” to find it. The all-new BoXXer streamlines racers into their “window of happiness” with adjusters that visibly indicate settings and make fine-tuning easy. No more counting clicks. No more wasted track time.

PREDICTABILITY IS LINEAR

LinearXL provides a position-sensitive linear curve. That means as you move through the travel, the rate at which the fork increases force never changes—delivering predictability. It’s supple off the top, supportive through the mid-stroke, and backed by an externally adjustable, jounce bottom-out system for confident end-stroke control. LinearXL’s whole fork approach also accounts for captured air in the lower legs, eliminating inconsistent speed sensitivity.

LINEARXL AIRANNEX

The AirAnnex on BoXXer’s lower leg increases the lower leg air volume, which reduces the air-spring progressivity and speed-sensitivity inherent to traditional lower leg designs. Transforming what was previously uncontrollable speed-sensitive progression into linear predictability for the racer.

STANCHIONS THAT BREATHE

Strategically placed breather holes in the stanchions allow for the lower leg air volume to increase as the fork goes through its travel. A small feature that transforms what was previously uncontrollable speed-sensitive progression into linear predictability for the racer.

CHARGER 3.2: SPEED-SENSITIVE AND SILENT

Re-tuned for the unique position-sensitivity of LinearXL, Charger 3.2 delivers speed-sensitive control with fully independent High Speed and Low Speed Compression damping. Because a damper should feel and sound incredible. That sound is silence.

PRECISION, NOT VIBRATION

Our most aggressively precise 38mm chassis, optimized for World Cup DH-winning speed—without the deflection and energy-robbing vibration typical of forks with excessively large stanchions. Put BoXXer where you want it.

CONSTANT BUSHING LUBRICATION: BUTTERWAGONTECH

ButterWagonTech is a proprietary matrix of divots on BoXXer stanchions that works to carry (or ‘wagon’) fresh layers of our exclusive, high-density Maxima oil to the bushings with every millimeter of travel. Unparalleled in design and function, ButterWagonTech sets a new benchmark for sensitivity.

BUTTERCUPS VIBRATION REDUCTION

Even the strongest and fastest athletes in the world experience fatigue and arm pump. ButterCups work to isolate the air spring and damper shafts from chatter, to reduce high-frequency vibration by up to 20%. Scientifically proven to keep racers fresher.
