Grivel G12 Cramp-O-Matic

A well-known system that relies on a nylon speed lever in the rear and a stainless steel front bale to hold the boot, the Grivel G12 Cramp-O-Matic crampon is quick to put on, and perfect for plastic mountaineering boots that have a rigid sole and substantial heel and toe welts.

The stainless steel safety strap is permanently mounted on the front bale and prevents total loss of the crampon should it be forced off the boot. Purchase the Grivel C2N bail conversion (sold separately) to make these crampons more versatile.
