The best choice for lightweight users hungry for victories. Its race setting is designed to provide an incredibly reactive hooking on the toe part and immediate release on the heel part, thanks to smoother and more gentle springs and to the addition of the ROLLING-IN® SYSTEM.Specifications:- Materials: Alu 7075, Titanium, POM- Release: Lightweight Race Setting- Ideal Skis: 60 - 82 mm- Weight: 800 grTechnology:Rolling-In System®:- The whole ATK® WORLD CUP heels U springs are made out of TITANIUM. This material provides an incredible lightness but is prone to wear and tear, with possible performance and safety ratio loss. The ROLLING-IN SYSTEM® is a revolution in this field. Two small HARDENED STEEL bushings (0,4 mm section) are applied to the front-end of the U spring, saving Titanium from wear and tear.Advantages:- 100% elimination of wear and tear, still keeping the titanium body extreme lightweight.- Easier step in and more precise vertical release thanks to the rolling bushings.Easy entry system:- This system is characterized by a new geometry of the toe part elements.Advantages:- Super easy and confident step in on the toe part, with any tech boot available on the market, even in case of worn out soles.Monolink® 1.0:- The ATK® R&D TEAM sourced a new aeronautical steel alloy that provides an extreme elastic modulus. Thanks to this special steel we were able to erase the half of the toe springs (from 4 to 2) and create a fix left arm, the so called MONOLINK® 1.0Advantages:- Weight reduction: 2,5 grams per toe part- Stiffness increased: lower pressure on the locking system with higher performances.
