Dynafit Speed Radical
A combination of forged aluminum, CrMo steel, stainless steel, and high-strength plastic provide plenty of strength and keep overall weight low (341g). No plate under the toe means that power gets transferred to your ski more directly. Speed Step heel-height adjustment system activates easily using your pole tip. Slideable heel piece allows you to gain or lose 12.5mm of length without remounting. Torx (steel) screws save weight and are ultra durable.
Built to be light, fast, and super-simple to use, Dynafit designed its TLT Speed Radical Binding to withstand the forces of traditional alpine touring and maintain the low overall weight that ski-mountaineers demand.
