Grivel Rambo 4 Crampons: Grivel's most technical crampon is now at its fourth evolution, integrating Grivel’s active anti-balling plate and simplifying all adjustments: just one screw to adjust the length, just one screw to substitute a point, just one screw to position the spur.
Rigid crampon with anatomic curve. Asymmetrical forged mono-point, extremely easy to substitute with just one screw, integrated with a half point external lateral support point: a new solution for external support.
Structure in rigid plastic acts as a spacer for the screws and as support for the supple rubber anti-balling device.
Accordeon in supple rubber holds together the front and rear parts of the anti balling system.
Four retention points for descent. Moveable spur.

• rigid crampon purpose built for steep ice and mixed climbing
