This is a Look by Plum Guide 12, all metal minimalist light weight tech binding. I had them on a pair of Dynastar Cham 107s and they were my favourite until the skis bit the dust. My replacement pair came with dynafits mounted so now I’ve just got these sweet bindings kicking around. Simple and strong in design. 12 DIN in the heel. Adjustable lengthwise in the heel so that you don’t have to remount them if you replace your boots.
Not break compatible, but can use a ski crampon with them. The newest version of this binding has breaks and retails for 479 €.
