Grivel - Air Tech Crampons
Grivel's Air Tech Crampons represent a new generation of "all condition" crampons, with ten points in contact with the ice while you are walking, 12 points that bite into the slope during traverses. This has been made possible because the third pair of points are shorter and wider apart. On top of this feature, the last two front points have double angulations to maintain bite while descending or traversing. The crampon points on the bottom are short and designed for the new requirements of "mixed moderns" alternating ice and rock making walking easier and more efficient. The front points are long like the G12's for vertical ice.
A well-known system which relies on a nylon speed lever in the rear and a stainless steel front bale to hold the boot. Quick to put on, these bindings are perfect for plastic mountaineering boots that have a rigid sole and substantial heel and toe welts. The stainless steel safety strap, which was invented by Grivel, is permanently mounted on the front bale and prevents total loss of the crampon should it be forced off the boot.
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, being far more versatile than the original Cramp-O-Matic style. Made in dual-component plastic: the black part is stronger, bearing the strain whilst the yellow part is softer, increasing adherence to the boot. The harness is made from the strongest, most durable plastic available: Zytel DuPont, which was developed for the manufacture of alpine ski bindings. Obviously it cannot last forever, so please, after long and severe use replace the harness the same way you would resole trekking boots or rock climbing shoes.
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. The single strap closure system is so simple we may not need to provide instructions; the New Classic is therefore ideal for rental programs and first time users. This system is simple and reliable, quick and easy, but it does take up a bit more space in the rucksack.
