Marker Alpinist Ski Bindings. The ultra-light Alpinist pin binding (270 g without brake) offers everything experienced touring skiers need. Its construction allows active length compensation without affecting the ski’s flex. A very stiff, ISI front makes the binding easier to step into, as a wide footprint with integrated stop automatically positions and aligns your boot. Kinematically optimised pin levers then allow the pins to snap shut with just a gentle push. The heel features 0°, 5° and 9° climbing aids and can be switched quickly and easily from ascent to descent mode. A 38 mm wide hole pattern transfers power brilliantly to the edges, which means control and great steering. Neutral walking mode and two climbing aids offering 5° and 9°. The fast shift mode enables quick shifting between 0° and 9° without the need to rotate the heel. Active length compensation in the heel allowing the heel to move back up to 4 mm when the ski is flexed. The ISI toe ensures that you’ll be able to get in and out of the toe really quickly and easily. Best Use : Snowsports, Freestyle Skiing, All Mountain Skiing.
