Ultralight crampon made entirely of Sandvik Nanoflex special steel: a metal alloy that, thanks to nanotechnology, is twice more resistant to tensile stress than thermally treated chrome molybdenum steel, and 20% harder. This allows a small cross section (1.8 mm) of the structure, which is to the advantage not only of the lightness, but also of the resistance and the low wear, with sharper and thinner teeth, which penetrate faster into the hard snow. The automatic binding is compatible with most ski touring and telemark boots.
Due to the reduced front area, Tour Nanotech is recommended for boots up to size 44 (size depends on boot, brand and model).
Sandvik Nanoflex is an innovative steel alloy with a 60 % higher strength than normal steel. This allows significant savings in material and weight.
