ROCKSHOX BoXXer Ultimate Charger 2.1 RC2 Debon Air 27.5" 200mm 36mm Straight 20x110 Red 00.4020.168.005

Built to be race ready out of the box, the World Cup winning BoXXer Ultimate features the completely re-tuned Charger™ 2.1 damper providing higher ride height during compression while keeping the tires glued to the ground on rebound. The combination of the DebonAir™ DH air spring, improved SKF wiper seals, SKF damper cartridge seals and Maxima Plush fluid add up to huge reductions in friction for unmatched control.

To celebrate its race-winning heritage, this version of BoXXer Ultimate proudly sports the same legendary BoXXer Red color that it did when it changed the DH world more than 20 years ago. Meet the Boxxer designed for the next generation of DH shredders.

Built from the ground up for big wheels, optimized lower legs, 35mm strong aluminium upper tubes in Fast Black and MX-inspired crown that allows optimized handlebar height. The DH-specific DebonAir air spring with 200mm travel offers riders the best attributes of coil and air: low breakaway force, mid-stroke support, linear feel and tunable progression. With the Charger™ 2.1 RC2 dampers riders are able to find the perfect level of adjustment for their ride, because it offers independent high and low speed compression adjustment. Furthermore it reduces riders fatigue, unwanted friction, overall weight, increases bump-sensitivity and traction, and reduces the force needed to turn knobs and lock in the best setting for the terrain. Furthermore its crowns lower the weight and compensating for taller wheel and tire combinations.
