Black Diamond O2

The O2 binding transmits power from big boots to big skis — it’s the benchmark of precision for today’s aggressive skiers. Underfoot cable routing and powerful compression-spring cartridges keep the ball of your foot firmly on the ski, and as the heel rises, a progressively stiffer flex delivers power. The rear yoke features a rigid wire heelpiece, providing lateral stability and torsional support. Our durable one-piece stainless steel toe box with a variable height toe riser withstands the abuse of hard and fast freeheel skiing. The stiffness of the O2 can be adjusted with the three different compression-spring cartridges to suit your boot flex or skiing style preference.
