A revolution in binding design, the O1 has become the benchmark in reliable downhill power and control with the added bonus of resistance-free touring for uphill efficiency. Push-button activation toggles between ski/tour modes with the simple touch of your ski pole tip. In tour mode, a smooth ergonomic pivot point just behind the pin line offers efficient climbing; in ski mode, underfoot cable routing and a pair of compression-spring cartridges deliver unmatched power and a predictable, progressive flex for precision downhill performance. A one-piece stainless steel toe box and solid-wire yoke heelpiece add torsional support and lateral control. With three cartridge options for customizing stiffness, the O1 is the ultimate, no-compromise freeheel binding. *These demos are almost new and show little to wear* Features: One-piece Toe Plate Progressive Active Flex Choice of 3 Spring Rates Full-coverage Skid Plate 27.5 mm Lift Specs: Standard: Over 305 mm Boot Sole Length Small: Under 305 mm Boot Sole Length Weight: 3 lb 11 oz, Std MidStiff Pair
