The goal of this binding is to reduce the risk of knee injuries that can occur in the event of a fall while skiing. While the toe piece of this binding operates the same way as a traditional ski binding, the heel piece offers both horizontal and vertical release which is different from traditional ski bindings. This technology in the heel piece allows for a decreased risk of knee injury especially backward twisting fall situations. As far as pure performance goes this is more than enough for almost every skier out there. It is right in line with traditional downhill bindings but if you've suffered knee injury before or want to be sure to decrease your risk of injury as much as possible while skiing, the Tyrolia Protector PR 13 is the move. While this binding does lower the risk of some knee injuries they're still possible, it's skiing. This binding is based on Tyrolia's PowerRail system and can be mounted onto any flat ski or skis that have a preexisiting Tyrolia PowerRail system on them.
