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.
