The ST Rotation 10 and 12 are both TÜV-certified Ski Touring Bindings with fully adjustable release values of 4-10 or 5-12. This binding spare part only includes the pivoting toe piece. The toe piece comes with screws. Since adjustments are not only dependent on the type of binding and boot, but also significantly on the type of skier, these are only to be carried out by an authorized professional who can test adjustments with the aid of an appropriate measurement device. Mounting and adjustments done by unauthorized personnel are at the risk of the user and may lead to termination of the warranty. Changes in adjustments from those recommended by authorized personnel may result in a risk of injury.
