The New Atomic Tracker is a revolutionary binding for backcountry & sidecountry skiing with DIN Alpine norm boots. You can switch from hike to ski mode without releasing the boot from the binding. The hike & ride switch is located right behind the heel piece & can be flipped with a ski pole. When it is time for you to start your descent once you have peeled off your skins flip down the climbing aid & stamp your heel down. A sturdy DIN range of 7-16 will make sure that you are in & staying in. The low profile chassis & 80 mm platform make this binding designed specifically for skis wider than 100 mm. 90 degrees of rotation at the toe make kick turns easy on the switchbacks. If you have been looking for a binding that has the retention & trust of an alpine binding, with the ability to hike & skin your way up to some freshies, the new Atomic Tracker 16 is the only way to go.
