RockShox BoXXer Ultimate D1 Fork, 29'', DebonAir+ W/ButterCups, 200mm, 1-1/8'', 20x110mm Boost TA, Rake: 52mm, Black

In the Ultimate version, the BoXXer Boost suspension fork from RockShox - here in the 29-inch version - comes with Charger 3 RC2 damping, which can be modulated, and of course the DebonAir+ air spring. Thanks to the double crown design, 200 mm travel and the new 38 mm chassis, it is ready to step on the gas on downhill tracks. The shock allows you to adjust the rebound as well as high- and low-speed compression. The proven DebonAir+ air spring makes you think you have a steel spring under the cockpit and absorbs bumps with ease. You'll also benefit from the ButterCups, which soften those continuous, high-frequency trail vibrations that can otherwise give your arms and hands a hard time. The stanchion tubes, which are thicker than in the previous model, provide you with a balance of high stiffness, precise control and ride quality. With the BoXXer, you simply rush over smaller roots and rocks, land safely after jumps and ride at speed.
