World-class downhillers such as Vali Höll and Loris Vergier have helped Rock Shox to develop the best Boxxer yet. The downhill fork comes with a new, stiffer 38-millimeter chassis and improved air suspension, which offers racers more progression but also the finest response. The Boxxer is damped with Rock Shox's Charger 3 RC2 damping and rounded off with vibration-damping butter cups.
