The Grivel G12 crampon is a classic 12-point crampon designed for general mountaineering, alpinism, mixed ice and rock climbing, and moderate waterfall routes. The four points that are perpendicular to the crampon rails, prevent shearing in soft snow and improve security while descending (facing outward). The Grivel G12 crampons are fully adjustable by hand, without tools and one size fits all. The Grivel G12 crampon is easily folded for transportation.
A well known system which relies on a nylon speed lever in the rear and a stainless steel front bale to hold the boot. These bindings are perfect for plastic mountaineering boots that have a rigid sole and substantial heel and toe welts.
An evolution of the Cramp-O-Matic system which utilizes the C-O-M rear bale and lever. The plastic harness system is hinged from two front posts which retain the boot securely even if it has a shallow, worn front welt or overboots are being used. It is a simple and efficient binding, which is far more versatile than the original Cramp-O-Matic style.
An evolution of the Classic binding. Both front and rear plastic harnesses are hinged from their respective retention posts and may be “opened” to facilitate attachment to the boot, then closed securely once the boot is inside.
