ATK HY 13 FREE

A freeride universe unlocked by the key of lightness.

High performance, high technologies high durability. The only thing that is not Hy in this binding is its weight.

No sweat transitions
Smooth and immediate transitions between ascent and descent modes, with no need for extra components or interchangeable parts.

Three walking modes

-18mm

• When used without heel raisers, it allows the boot heel to drop slightly below the toe level. This 18mm difference enhances stride extension and walking efficiency during long and flat approach.
• This design is especially beneficial for skiers using freeride boots with a cuff that offers limited mobility.

+10mm

• The Hy also features two heel raisers for easier uphill progress, both activated easily even with the pole.
• The first one gives a similar "flat" sensation.

+34mm

• The Hy also features two heel raisers for easier uphill progress, both activated easily even with the pole.
• The second heel raiser is useful on the steeper sections of the ascent.

Flat skiing

In ski mode, the boot sits flat on the ski, eliminating the rear-front pin height differential typical of standard pin bindings. This design delivers an alpine-like feel and performance.

Heel clamps

The heel clamps, inspired by the alpine system, offers a spectacular sense of control and precision.

Adjustable AFD

Correct Anti Friction Device (AFD) adjustment is essential for compatibility with various sole types. To achieve this, we have developed specific spacers that fit between the sliding section of the AFD and its underlying structure.

Compatiblity

The Hy is compatible with most alpine skiing, ski mountaineering, and freeride boots. Thinner plastic soles provide a stiff connection with the binding. For this reason, we designed softer spacers that also serve to dampen vibrations. Thicker rubber soles require little to no spacers, as their rubber composition inherently provides vibration absorption.
