The G12 Crampon by Grivel 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 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.

Awesome 12-pt crampons!I wear the cramp-o-matic G12's with my Sportiva Spantik boots and they fit great! Excellent all-around crampon for glacier travel and routes that aren't very technical. I ended up buying the asymetrical center bars from Grivel to get a better fit to the curve of the boot but I only found that necessary because I have a small boot size and so when I had the crampond adjusted to such a small length, they really didn't curve as much to fit the boot curve as they would if I had the bar set longer. Probably not necessary for most people and I probably would've been fine with the standard bars anyway.

Classic crampon -- easily adjustableAcquired and used on 2 attempts (one successful -- yay me!) on Shasta in the past month. Expand to fit my size 14 double plastic mountaineering boots quite easily. Rock solid connection with the boot, having not come loose in two full summit days. Can't really even make any suggestions for improvement for mountaineering!
