The Race Brake System developed by ATK is unique in its kind. When the skier switches the heel flap to switch from uphill to downhill mode, the brake activates automatically. Similarly, when the skier wants to go back to uphill mode and switches the heel flap position, the brake locks without requiring any other movement.

This system is characterised by a new design of the toe piece. Its innovative geometries allows a smooth step-in, safe and easy to perform on all the latest boots models. Effective even if the soles are worn.

A multi-position selector between the front lever and the toe lug. By changing the setting of the selector, the stiffness of the toe-lug lock in up-hill mode can be adjusted by increasing pressure on the locking system.

The U-shaped springs of ATK's WORLD CUP heel pieces are made of titanium. This metal provides incredible lightness, but is prone to wear and tear. This might lower the performance and safety level of the binding. The ROLLING-IN SYSTEM® has revolutionised this field: two small hardened steel bushings (0,4 mm wide) are applied to the front of the U-shaped spring, preventing wear and tear.

No snow debris under the toe part, even with several up-hill/downhill transitions. This also avoids snow loads on the toe piece, granting a perfect lightness at any moment.
