Grivel G12 Crampons - New-matic & New-classic binding systems A classic 12-point crampon designed for general mountaineering, alpinism, mixed ice and rock climbing, and moderate waterfall routes. The Grivel G12 is \"the king of crampons\", used for climbing mountains all around the world. It has 12 points, 8 of which in the front and 4 in the back, allowing a perfect stability and performance in all snow and ice conditions. The four points that are perpendicular to the crampon rails, prevent shearing in soft snow and improve security while descending (facing outward). The G12 crampons are equipped with the famous Grivel proactive Antibott both in the front and the rear. The Grivel G12 crampons are fully adjustable by hand, without tools and one size fits to any type of boot. They are also easily folded for transportation. A 12-point crampon for all types of mountaineering that makes strength and reliability of its strongest points! \"Years go by but my G12s are always there in the backpack. It is a performing crampon on all terrains, a tool that has made the history of mountaineering and that still has time to revolutionize it. We are inseparable. I prefer the G12 on mixed terrain characterized by long stretches of fresh snow, where you have to make the track and in the Himalayas where you often move without rope and there is no margin for any error. As on the south face of Shishapangma 8027 m. The front points that allow you to have exceptional support and hold. I do not have a ranking of climbs with the G12, but the Couloir opened with my father on the south face of the Matterhorn is a precious memory.\" - Hervé Barmasse, Grivel Team. Valtournenche, Italy, 42 years old, alpinist, mountain guide, mountain guide instructor, member of the Cervino Mountain Guides Association. \"The best crampon for snow routes, it is ideal for tackling classic itineraries such as the crossing of the Lyskamm or the Trois Monts on Mont Blanc. But it also fits perfectly on more demanding routes such as on the Brenva Spur or the north of the Breithorn. The long front points penetrate well into the ice and hard snow giving it perfect stability. My best climbs on the G12: Lhotse without oxygen, and Everest with a client.\" - François Cazzanelli, Grivel Team. Cervinia, Italy, 30 years old, alpinist and mountain guide, member of the Cervino Mountain Guides Association. \"I use the G12 for classic mountaineering through technical alpinism. The shape of the crampon perfectly traces the edge of the boot. So i always know where the points are, they’re right under the edge of my boot, exactly where I want them to be. I used these crampons on the Rupal Face Ascent (as did Vince) on Nanga Parbat in 2005, my most famous climb for sure.\" - Steve House, Grivel Team - Colorado, USA, 49 years old, alpinist and mountain guide, Piolet d’Or 2005 winner.

The problem was well known for many years! The first idea of an anti-snow system was the plastic insole of the Foot Fangs designed by Mike Lowe in 1972, but it didn\'t work very well. In 1997 Grivel was the first company to deliver all its crampons equipped with an efficient anti-snow system designed by New Alp. Finally in 2003 Grivel put an end to the problems of accumulating snow under crampons with the first proactive antibott, the one that at every step unloads the snow and that, with its elastic action, takes advantage of the alpinist\'s walking movement.  The Grivel proactive antibott remains the most efficient and the only one working in all snow conditions. It is a real safety system and it is patented!
