The snow pack under the toe piece creates troubles in certain snow conditions and when changing several times from up-hill to downhill mode on the same tour. No more snow pack under the toe piece thanks to the SNOW PACK PROOF SYSTEM® (patented) which avoids the snow, ice or debris entrance under the toe piece locking mechanism.Specifications:- Materials: Alu Alloys, POM, Stainless Steel- Release: 5-12- Adjustment: 25 mm- Ski brake: 86, 91, 97, 102, 108, 120 mm- Ideal Skis: 80 - 120 mm- Weight: 1000 - 1700 grTechnology:Fast-In System®:- The FAST-IN SYSTEM® consists in a special design of the toe part: the front lever is meant to stop the boot in the perfect position for the step-in.Advantages:- Extremely intuitive and fast step-in with any tech boot.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.Snow pack proof:- A special design of the toe part that avoids any snow/ ice/debris build-up under the hookingAdvantages:- No snow pack under the toe part, even with several up-hill/downhill transitions.- Avoids snow loads on the toe piece, granting a perfect lightness at any moment.UP-Hill Hardness Variator:- This system is an exclusive privilege of the RT, R12 and FR14 families. A multi-position selector is placed in between the front lever and the toe piece base plate. By changing the selector setting, the up-hill mode locking hardness variates by increasing the pressure on the locking mechanism.Advantages:- It compensates the boot toe insert wear and tear during the years.- Provides a proper locking strength for each user (softer for lighter users, harder for strong ones).- Reduces the pressures on the locking mechanism.Cam Release System®:- The king of the ATK® patented systems! The CAM RELEASE SYSTEM® is fitted inside of our touring bindings heels in order to drive the boot step-in and vertical release in case of fall. A special CAM profile is pressed towards the heel pins by a pre-tensioned spring: when the step-in or a fall release occur, the pins are forced to go through the CAM profile which provides a precise resistance to the pin release, depending on the release value set on the binding.Advantages:- Provides the most stable downhill performances on the market with consistent reduction of boot torsion compared to any other tech heel part.- Extremely precise release performance.- Provides the softest heel step in of the industry.- Small dimensions compared to performance and astonishing lightweight.Magneto Heel Flaps:- An ingenious as simple magnet system provides the handling and stabilization of the heel flaps.Advantages:- Extremely light and comfortable heel flaps systemElastic Response System:- A spring is placed in between the base plate of the binding and the adjustment screw. When the ski bents under the effect of a compression or a jump, the 4 mm distance in between boot and heel can be reduced or deleted and the heel part can slide backward and forward under the effect of the spring.Advantages:- Grants the natural ski flex, also in case of big jumps/compressions.- Improves binding release performance when the binding is stressed.- Reduces the pressure on the ski-boot-binding system.
