Avoidance of negative bending effects
A conventional ski has a binding plate directly under the boot binding. This reinforces the ski in the middle section. When carving, the ski bends corresponding to its side cut. During this bending, a larger bending radius results due to the binding plate in the middle of the ski. The tip of the ski and its end show a smaller bending radius. Therefore, a curve cannot be conducted without a braking effect. A bending test in the Institute for Snow and Avalanche Research SLF in Davos proved that the negative effect of the binding plate (refer to the black bending line) is avoided by the ACTRIF (refer to the petrol coloured bending line).
