It isn't often you see a totally new design in alpine ski bindings - in fact, many of the popular bindings on the market today bear striking similarity to the designs those same companies used decades ago. The Tyrolia Protector PR 11 GW Ski Bindings break new ground with an innovative design intended to reduce the incidence of twisting ACL injuries, traditionally the bane of skier's knees. The Tyrolia FRH (Full Release Heel) allows full 180˚ release both vertically and laterally (the heel rotates 30˚ to either side) to better allow release in loaded twisting falls. The first time this binding prevents a blown ACL, you'll be glad you placed your trust in it.
