The Harfang Tour has an aluminum front, secondary and rear rail. This is the go to crampon when light and fast are the best choice. The middle rail can be fully removed to give you the even lighter set-up for racing. This patented concept is based on a central main textile strap that connects the front and back rail and allow to mount it in the most suitable position base on the application or the geometry of the boots. The main strap flexible linking system minimizes bulk and offers a real compactness. The Harfang Tour is designed to fit any boot with a heel welt and includes two front bail systems: fully auto and semi-auto which are interchangeable.
