The Tyrolia Protector PR 11 GW Bindings with full heel release technology offer maximum safety in forward or back twisting falls by reducing release values, therefore assuring less stress for your knees and by providing safer skiing. Conventional bindings are designed to reduce the risk of injuries to the lower leg below the knee, but they are not intended for preventing injuries to the knee. Thanks to the Protectors full heel release, this binding can reduce ACL strain by more than 50%. Features include an RX Toe that provides maximum responsiveness to the skier's edge for precise turns. A 33.5 stand height gives you the quickest and most exact response you can find in a binding. The HR Heel keeps your boot as secure as possible in the binding, that way you don't lose an ounce of power from your boot to the skis edge. With 7 -millimeters of bilateral movement, the elasticity absorbs all impacts on the binding and avoids those dreaded pre-releases. With a DIN range of 3-11, The Protector PR 11 GW accommodates a wide variety of skier ability levels, and at 2320 grams, is pretty light too. For skiers who are coming off a knee injury or for older knees that have seen lots of action over the years, the Tyrolia Protector PR 11 GW Bindings would be an ideal match for skiers of all ages, ability levels and styles.
