The Black Diamond O3 telemark binding is for skiers who prefer a classic, neutral-feeling, but can do without the slop of old school cable bindings. With a less active flex, the O3 backs off a little on power, but keeps the driver firmly in control. The softer, traditional feel of this binding creates less resistance during deep-knee turns, but the underfoot cable routing maintains positive contact with the sole of your boot for greater control and ski stability. O3s are available with three cartridge options for customizing stiffness to provide predictable and precise control over the ski and the ability to distribute force during the entire turn.
