Description
Born from racing, BoXXer Ulitimate promises one thing above all-composure. By eliminating chaos before it reaches the rider, every run delivers predictable speed, traction, and control. The all-new LinearXL air spring provides a coil-like ride-supple off the top, supportive through the mid-stroke, and backed by a jounce bottom-out bumper for confident end-stroke control-giving you unwavering consistency and predictability. Found only in our Ultimate forks, ButterWagonTech ensures a constant supply of oil to the bushings, reducing friction and maintaining smooth performance throughout the entire service interval. Intuitive HSC/LSC controls on the Charger 3.2 damper with ButterCups technology make setup fast, understandable, and easy to communicate. You’re so composed you don’t realize you’re going faster. But the clock says it all.
