Podium-driven composure defines the BoXXer Ultimate Charger 3.2 29in Boost Fork

What Our Gearhead® Experts Are Saying:


"If you’re racing a 29er downhill bike, this is the top-tier option. It’s incredibly predictable through rough sections, and the RC2 controls make setup straightforward between practice runs."


Designed for downhill racing, the BoXXer Ultimate Charger 3.2 29in Boost Fork refines performance through predictability. LinearXL’s position-sensitive linear curve reduces speed sensitivity and maintains consistent support through the entire stroke. A jounce bottom-out bumper controls deep compressions with precision.


The Charger 3.2 RC2 damper delivers fully independent high-speed and low-speed compression adjustment, tuned to complement the LinearXL spring. ButterCups reduce high-frequency vibration to help preserve rider energy, while ButterWagonTech continuously carries Maxima oil to bushings for sustained low-friction performance. SKF wiper seals further enhance sensitivity.
