Rambo 4 is part of the technical crampon family. It is totally rigid. It has a forged front point that can be replaced with a single screw. The forging allows a three-dimensional shape to improve both the penetration into the ice, without rebounds, and the support. The adjustment is convenient because it is also done by means of a single screw. The position of each point is designed to provide greater stability in all climbing positions and on all forms of ice. Equipped with the famous Grivel proactive Antibott system both on the front and on the back.
