RockShoxMY26 BoXXer Ultimate Charger 3.2 is a race-focused downhill suspension fork built to keep a 29er chassis calm under braking bumps, compressions, and high-speed chatter. With a 29" wheel platform and 48mm offset, it targets precise tracking and predictable steering feel when speeds rise and the line gets rough.
Race-day advantages that matter on the clock
Charger 3.2 damper with HSC/LSC adjustment - High- and low-speed compression controls make it straightforward to add support for steep braking zones without sacrificing small-bump traction.
LinearXL air spring - Delivers a coil-like ride balance (supple off the top, supportive in the mid-stroke) with a jounce bottom-out bumper for controlled end-stroke feel on big impacts.
ButterCups technology - Helps filter high-frequency vibration; RockShox rates it at up to 20% reduction in “trail chatter” to reduce hand and arm fatigue on long, rough runs.
ButterWagonTech lubrication management - Maintains a consistent oil supply to the bushings to reduce friction and keep the fork feeling smooth throughout the service interval.
Low-Grab SKF wiper seals + Maxima 920 (15w) lubricant - Focused on minimizing seal drag and overall friction for more consistent sensitivity and longer-lasting performance.
Bolt-on fender compatibility supports front and rear coverage using the BoXXer Bolt-On Fender (sold separately), helping riders keep vision and stanchions cleaner in wet race-day conditions.
