Dynafit has lighter bindings for races, but the Superlite 150 Binding is the lightest option for speed touring. It weighs a mere five ounces and still holds reliable release ratings for rowdy downhill riding. The front piece is completely fixed for solid retention that optimizes power transfer on the ski's natural flex, and despite its minimalist appeal, the heel piece still has a heel elevator for extra assistance on steeper tours. There are attachments for crampons, ski brakes, and an adjustment plate to accommodate ski boots you might buy in the future.
