Grivel G12 Crampon

They last forever and a day. More durtable in my experince than stainless. Good design for all around ice and good support on the first two sets of points. Great boot fit as well. Get the Grivel Tech if you want to do a lot of mixed. But these will work well there as well.

Im a big fan of Grivel products. Their crampons are next to none as far as I am concerned. The G12 is no exception. The points are well angled well designed to last for a long time. I have ascended everything from vertical to gradual icy slopes with these and they haven't let me down, the cramp o matic design is great and very secure. These are a must have in just about every winter alpenists gear bag.

So far I've only had them on some gradual/easy routes in the sierras, but so far i really like them...

definitely the easiest 12 point crampon ive used for simple snow/glacier travel, but also worked well for more vertical mixed routes....so far a nice compromise

I've got the full clip-in version (new-matic). Just took these to Mt. Shasta to do Casaval Ridge. They are solid...no doubt ever that they'd stay on and remain firmly connected. There was no issue with snow collecting under them later in the day. The teeth are nice and secure. There's incredible detail in the design. They work well with my new La Sportiva Baruntse boots. The last pair of crampons I've been using are Black Diamond Contact Strap ten point crampons. Those were nice too, and you really can't compare them. I'm a huge Black Diamond fan. But I'll just say I like the Grivels more when it comes to mountaineering crampons. That being said, I haven't tried out the twelve point clip-in Black Diamond crampons. But I do like Grivel's detailed design. Their kind of designs remind me of the detailed designs produced by LibTech for snowboards (if you happen to be a snowboarder). There's just a lot of attention to detail. If I were looking for some solid mountaineering crampons that'd work great for technical climbing (but not full on waterfall ice), I'd grab a pair of these.

Pretty awesome crampons. These are very durable and fit my Koflach degrees perfectly. They go on very fast even when your hands are cold and the design of the straps (I have the Newmatic version) minimizes fiddling.

I have been using these crampons (with the hybrid binding) for four seasons and they are still in great shape. I have really appreciated some of the details: (1) The heel points are a little flat, rather than pointed, so they brake better. (2) The heel lever adjustment is on the inside so there is less of a chance to damage it when wallowing in snow-covered rock. (3) The strap buckle openings are round, not rectangular, which helps with loosening when partially frozen. (4) The buckle has a Hypalon tab so it is easier to loosen it with gloves on. (5) The antibott plates flex so they are more effective than rigid ones.

as a female with a narrow heel, finding a crampon that stays on my boots are key, and finding a crampon that prevents balling and added weight is even more important! these grivels do all that and remain sharp and spikey. I highly recommend them, easy to put on even with thick mittens on, easy to adjust and they keep their edge. I would recommend getting a crampon bag whe buying these or any crampons to keep them safe in your pack

I've had these crampons for more than 10 years and they are still kicking. I've had them on Rainier, Denali and Aconcagua with no problems. Works great over Koflach boots, which they don't make anymore (very sad), but highly adjustable and fits a wide range of boot sizes.

Far better and more versitile than standard 10 point "general mountaineering" crampons. More agressive secondary points allow for more secure and efficient front pointing giving you more confidence on steep ice. New-Matic and New-Classic are great options for binding systems. New-Matic still works without substantial heel welts.

Used on denali. Used to have some Petzl vasaks. These are amazing in comparison due to their Anti Balling plates and sheer traction. My new go to crampon.

These are great. Easy to put on and adjust, they have great hold, and are an all around versatile and high quality crampon. I have size 13 boot (Asolo brand, US size) and they just fit when using a nut+bolt to hold the bar. Anyone w/bigger feet will need to buy the extension bar.

This crampon is great! Glaicers, snowslopes, ice...this takes it all. It is easy to adjust with its macro and mirco adjustments and once it's on the boot, it stays on. The antibot plates keep the snow off the bottoms so you always have points making contact with snow/ice. You can even ice climb in them, even with the horizontal front points. They look pretty sweet too.

Performs very well on alpine routes and soft waterfall ice. The horizontal front points dont shear threw snow like vertical ones, the trade off is that they dont penetrate hard ice well and are just ok on hard mixed stuff. Bottom line: the best out there for alpine. Hard water ice and mixed, look elswhere.

It was time to finally bail on my Rambo's sadly so after much research I bought these and have been pretty much totally psyched about them. Very user friendly, easy to use, performance is great, I could go into technical detail but I'm not paid for this so I'll just say my man borrowed them to climb Denali (ten years after i climbed it) and he loved them as well. Ice, alpine, they are great.
