The BoXXer Ultimate with Charger 3 RC2 is a world-class downhill fork built to meet the demands of the fastest tracks and most aggressive riders. Featuring a stiff 38 mm chassis, a new damper architecture, and a DebonAir+ air spring tuned specifically for DH use, it offers the support, sensitivity, and consistency required for podium-level performance.

At the heart of the fork is the Charger 3 RC2 damper, which provides truly independent high- and low-speed compression adjustment, plus low-speed rebound. Its re-engineered layout eliminates cross-talk between adjustments, delivering more usable clicks and more predictable handling. The damper and air spring both include integrated ButterCups to absorb trail vibration and reduce arm fatigue on long descents.

The BoXXer Ultimate is built around a dual-crown layout for maximum steering precision and chassis stability, making it ideal for bike park laps, DH racing, and big mountain riding.

Installation Notes

Professional installation recommended unless experienced. Requires proper crown race installation, steerer tube trimming, and torque checks on all fasteners. After fitting, set sag, air pressure, and damping to suit rider weight and track conditions. Recheck crown bolts and axle torque after the first ride.
