The Marker Duke 16 ski binding is a big-mountain free skiing binding with alpine touring capabilities. Designed for the skier who wants to be able to ascend in the back country, yet still jump cliffs and ski varied conditions during the descent. Designed from the ground-up for the modern free-rider, the Duke has all of the know-how and ski performance experience garnered by Marker over more than 50 years with the additional hiking mode desired by the back country skier. To switch from touring mode to ride mode, a rider must take the ski off, pop up the underfoot lever, then put the ski back on, which guarantees the binding will not inadvertently open in ski mode. With the shortest frame of all hiking models on the market, the Marker Duke allows your ski to flex naturally. In addition, Marker’s excellent Power-Width-Design allows for maximum power transmission. An adjustable toe height feature gives you an incredibly solid connection with your boot. In tour mode, the binding moves your center of mass backward 30mm for greater efficiency. Din 6-16. Recommended skiers weight is 130 +lbs.
