New Matic

New Classic

Grivel G12 Crampons

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 crampons are fully adjustable by hand, without tools and one size fits all. G12 is easily folded for transportation. The G12 crampon is delivered with the Antibott included.

New Matic: An evolution of the Cramp-O-Matic system which utilises 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. 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.

New Classic: 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.

Climbed Mt. San Jacinto wearing these most of the way. Very tough, wasn't worried when the trail changed from ice to rocks. My friends were jealous.

Used these about 4 times since I got them, and I have to say, they did offer great grip, wear extremely well, and since they came with the long bars, they fit my size 11.5 plastics extremely well. I've also tried the fit on my size 11 leathers and they worked out great too. I usually expect alot from Grivel(I use their equipment almost exclusively) and was in no way dissapointed by these. After the 4 trips I'm surprised to see they show very little wear on the teeth, to the extent that it looks like I only used them on snow, when infact they were used on many mixed up and rocky sections. Aside from a little silver of the metal showing through the black oxide coating, they still look brand new.

This is my second pair of Grivel G12 crampons. I've climbed with them on Rainier, in South America and Nepal. I recently gave mine away so I promptly purchased a new pair. They are excellent with the Koflach Double Plastic Boots. I used the last pair for years and never had an issue.

Got the Newmatic, Great quality, fit perfect on my pair of 11UK Invernos(would need the extenders if you went any larger). Anti-balling works well.

I just recently bought a pair of G12s to replace a 10 point pair of Grivel's that I really enjoyed and had superior performance. (even without the antibot technology they never collected snow and ice in any conditions) The G12 took performance to another level with the anti-balling technology. I am currently training to climb Rainer this summer and I wanted to try them out to make sure I am familiar with them and how they will perform. I used them to summit Mt. Rose (10,800) and then enjoyed secure footing all the way down to 8,000 feet on a very warm sunny day. Even my snowshoes had been collecting snow earlier. Unlike my snowshoes there was no accumulation with these crampons at all. I also appreciate the convenience of being able to strap them on any boot.

I got the Classic G12 with the straps, Ive only used them a few times since i bought them, but so far so good. The front points are very aggressive and great for steeper icy slopes. The straps are very easy to cinch tight and the crampon is surprisingly solid on the boot. I got the straps because i wanted a crampon that i could use with my leather hiking boots if i needed to, but i also wanted a crampon that i could use with plastic boots for general mountaineering and maybe even ice climbing.

I have the standard strap on binding without the heel bail shown in the first picture. I have used the crampons with a set of Koflach's and have had no problems with them. I bought the crampons before the boots so was concerned with compatibility due to not knowing the type of boots I would buy. I bought them used, but they were easily sharpened and look to have many years left in them. I have used them in snow, and on ice climbs and have experienced no issues with the crampon sliding around. Next time knowing the boots I have I would buy a set with the heel bail, but do not regret the purchase that I made.
