Grivel’s most technical crampon, now in its fourth version, the Grivel Rambo 4 Crampons find their mark in the high performance mixed climbing market.

Fully customisable, the Rambo 4 Crampons feature a moveable spur, adjusted with only one screw. To simplify matters further, the Rambo 4 Crampons use only one screw for adjusting length and substituting a point.

The Rambo 4 Crampons are a twelve spike crampon, constructed from Chromolly Steel, and with an asymmetrically forged mono point. An accordion of supple rubber holds the front and rear parts of the included anti-balling system in place, while the rigid plastic in the structure acts as a spacer for the screws and supports the anti-balling system.

The Rambo 4 Crampons are available with the Cramp-O-Matic binding system suited to plastic mountaineering boots with a rigid sole and substantial toe and heel welts. A nylon speed lever at the rear secures the boot, and a fixed stainless steel front bale prevents total loss of the crampon should they be forced from the boot.
