Great crampons but had to modify to fit
These crampons are easy to put on and served their purpose well during a 5 day course and climb of Mount Baker. Although they say one size, I did have to modify to fit my smaller La Sportiva Evos size 40.5. We had to pry the center black bar over the back lip to make small enough, but worked great after the adjustment. The overhang doesnât interfere with usage, but would caution those purchasing with boot sizes under 40.

Excellent for ice/snow and everything
I climbed Mt elbrus recently and wanted to buy my own crampons. I decided to go with Grivel. Its sharp, lightweight (As a woman this counts more because I . am 120lbs), easy to carry. The only complaint is ice gets stuck between the front and my boots but thats solvable by a little jolt from my ice axe. Highly recommend for other petite women.

All-around Alpine Workhorse
I've used many different brands of crampon and settled on the G12 "Cramp-o-Matic" as my all-around pair o' spikes. These crampons performed well on WI4+ sport laps in Colorado as well as load-carrying up steep frozen snow slopes in the Andes. These crampons are quite stiff and performed well on all footwear I put them on. While some folks prefer to have vertical front points, I find the horizontal spikes can be just as secure (with good footwork) on vertical ice and still perform just as well on less technical terrain. That being said, I would not recommend these crampons for mixed climbing or very overhanging ice lines. The fit: These crampons were among the easiest to adjust that I have used. The toe bails fit snuggly to both my climbing boots and touring boots. The heels are very secure and I did not feel any wiggle even when navigating short rock sections in them. The adjustment system took a few tries to get right but now I can change the length quickly and easily from my touring boots (Scarpa Maestrale 27.5) to my climbing boots (La Sport Nepal's 44). I'm a huge fan of the front leash loop. No more fiddling around to run your ankle leash under your toe bail in less than ideal conditions (Warning, this metal part is quite sharp and put a hole in a pair of liner gloves but I guess that's part of the joy of alpine climbing). Also, the bright yellow is a nice feature for trying to find your gear during alpine starts.

Gave as a gift
Gifted these to a friend and here's his review: I purchased the G12's to fit some more flexible mountaineering boots that don't have the front tow bale. For flat-steepish terrain these are ideal. The anti-ball plates really help evacuate the snow out of the crampon. I trust all of their products. I can't afford to have a wardrobe malfunction, especially in a remote location.

I bought these as a gift for my boyfriend and here's what he had to say! "These crampons are the gold standard for a one-quiver crampon! I use the Cramp-O-Matics on my La Sportiva Nepal Evoâs and they work like a dream. They are extremely sharp right out of the box and only take a few min to adjust. My Nepals are size 43.5 and these have plenty of room to adjust larger or smaller. Iâve used them for steep snow and vertical ice and they are great for both. Would you rather have vertical mono points in the front for hard ice climbing? Sure.. but these work pretty darn well and keep in mind that there are countless classic ice routes were put up with wooden shafted ice axes and ice pitons! If you are looking for a general mountaineering crampon that will also work well enough for ice climbing, the G12âs are what you are looking for. As bonus info, these WILL fit on Scarpa NTN telemark boots. The toe piece requires some enthusiasm to seat but once locked into place, are remarkably solid. "

Little problem with small boots
I bought a G12 for Zamberlan 39 EU. The fastenings in the nose and back were wider than the boot. But the problem is solved, if you tighten the clamp tightly behind, it helps fix the crampon, and the shoe stops hanging to the right - to the left.
January 26, 2018
Fit the Scarpa Maestrale and sharp out of box. Haven't needed maintenance yet.

Favorite all around crampon
I like to use these as my main all-mountain crampon. So well built, you would think they were made in Italy. Oh wait.. they are. Bomber.

Near perfect fit
Got these to pair with La Sportiva Baruntse, 47.5/13.5, with the 190mm extension bars (at smallest adjustment with extension bar, also fit Nepal Cube GTX), and they fit almost perfectly! Just a slight 3/16" gap between the front welt and crampon, but makes great contact overall. Simple to use and adjust! Will need to see how front cage holds up, but seems it will be sturdy enough for what I need (not ice walls). Will update if I ever have issues.
September 10, 2017
Does it all. Quick and easy with step in set up. Not much else to say about it.
June 22, 2017
Fits my Spantiks
Had to get the extender bar, but it fits my 47 Spantiks well.

Great for Mountaineering
I picked up these crampons after experiencing a fit issue with a different brand, and I'm pretty happy I did. The crampons were easy to adjust to the correct length and they fit my Koflach Degre mountaineering boots (US size 11) great. The crampomatic system makes them easy to put on and take off with gloves on. I've taken them up a few alpine climbs and some easy-to-moderate vertical ice, and they haven't let me down yet. They appear to be solidly built and durable - no surprise, as in my experience Grivel makes great products. They're a great crampon for mountaineering and easy-to-moderate ice. My only minor complaints are that I don't have an easy way to tuck away or otherwise secure the additional strap length after they're fully attached. It would be nice if there was a clip or something along the strap to tuck it away - I've been tying the strap back on itself but that has come loose a few times. Also, it would be nice if the crampons came with a bag.

A great crampon, fits my scarpa boots just fine.
March 22, 2017
I bought this for my mountaineering uncle for his latest summit up Mt Washington. He had this to say: "Glad I had the Cramp-O-Matics! They were easy to get on, even with my gloves on...and when it is that cold...taking the gloves off is not a good option."
January 9, 2017
Climbed Orizaba in these
.... didn't summit, but it wasn't due to the crampons. Easy on/off with cold fingers and gloves. Fit well on my La Sportiva G2

Good for BC ski and mountaineering
I used these with the La Sportiva Nepal EVO GTX mountaineering boot and my Scarpa ski boot and it fits perfectly. I have the cramp-o-matic version and that's the one I would recommend because of tighter fit than the New-matic. I use it for easier mountaineering trip and backcountry skiing. For that the crampon fits perfectly and feels very robust. I probably wouldn't use it for vertical ice climbing though and go with something a little bit more aggressive. Note on size: it fits my size 13 Scarpa Maestrale ski boot with a little bit of room to spare with the regular out-of-the box center metal bar. If you want to use it on very small boots, you will have to flip the center bar over. There is a nob that will make the center bar not fully extend.

Worked for Hood and Adams!
My customer Keith putting his G12's to good use up on Mt. Hood.
March 23, 2016
This crampon can do just about anything. Whether snow climbing, vertical ice, or glacier travel these can do it all with confidence. Not to say they do everything the best, that's probably impossible, but these will not let you down in the mountains. They also adjust super easy to fit between a mountaineering boot and ski boot. I wish they came with a crampon bag. That's about the only "con" I have for the purchase.
June 19, 2016
Hey Kyle - wanted to ask since it looks like you're using Scarpa Maestrales in your photo. What crampon binding are you using? I'm guessing the 'Crampomatic' style? Do you find they fit on the back of the boot well? Almost every other pon I've tried has interfered with the walk mode switch or hasn't been able to close fully. Thanks!
August 23, 2016
Tobin, sorry just saw this. Those are the Salomon MTN explore boots. Crampomatic is the binding style. It does not interfere at all with the boot.
October 1, 2015
These are perfect so far. Easy to get on and size. Hold in the ice well.
December 17, 2014
Easy and solid.
These were simple to pair with my La Sportiva Nepal boots. Snug, perfect match, easy to put on and super stable footing. Haven't tested them on super advanced terrain yet but can't wait. So far so good.
February 9, 2018
So I am just starting with mountaineering. I don't have money for mountaineering boots yet and don't need them for a while from what I was told. Will the new classics be my best bet for normal winter boots? Will they work with most types of boots and even shoes if for some reason I wanted them for that?
May 12, 2018
Yes, the new classics will the best choice for your needs as they should fit all boots. The new-matics require that the boots have heel welts to fit and the cramp-o-matics require both heel and toe welts, and though they are more secure than the new classics, they work with a smaller range of boots. Go with the new classics if you want to use them with virtually any boots.

What brand of crampons seems to be the best? I've always thought of black diamond or petzl but I've never heard of Grivel so I'm not sure if they are quality?
November 10, 2015
Phoebe, For crampons the top companies are going to be CAMP USA, Grivel, Black Diamond and Petzl. What type of terrain are you looking to be on? Shoot me an email anytime you have questions! Jared D. Expert Gearhead 801.736.4336 email@example.com

what size would recommend for size 9 snowboard boot?
May 1, 2015
They're one size and with a size 9 boot you will not need the longer center bar. The wide version will fit better!
March 18, 2015
Which attachment system would be best with AT boots? I am guessing the cramp-o-matic.
March 19, 2015
You have guessed correctly! The Cramp-O-Matic is the most secure fit to your AT Boots. You can call or email me directly. 801-736-6398, or firstname.lastname@example.org

Is it possible to use new-matic crampons...
Is it possible to use new-matic crampons with lighter hiking boots (i.e. ones without a heel 'welt'), or are you forced to use a strap style??
March 27, 2014
Toe and heel welts are what really keep the crampon in place for a New-Matic style crampon. If you are planning on using boots without welts you are going to have to get a pair of strap on crampons.

Will these fit an AT ski boot such as the Salomon Quest 12?
May 23, 2013
Yes. I have the BD Factor 130s (27.5), and my G12s with new matic bindings fit them.

depends on the boot size; mondo 30 will likely not fit.

Hi, Just looking at the Grivel G12 with the Cramp-O-Matic front bail. Question: What size range boots is the XL version designed for? Thanks!
February 14, 2013
These crampons only come in one size with the standard center bar. You can purchase the Grivel long bar separately which adds 30mm more ( long bar is 190mm) space to accommodate larger boots. Grivel advertises that the standard center bar should fit up to a size EU 47, which is US 14, though this would be unlikely in a pair of double mountaineering boots. From personal experience, I've fitted climbers with US 15 Scarpa Inverno plastic boot with the long bar and it fits well. Check out the Grivel Long Flex Bar: http://www.backcountry.com/grivel-flex-long-bar

In looking into the cramp-o-matic G-12's I noticed that they offer the XL cramp-o-matic. I wear a size 12 boot. Will I need the XL? Thanks for the info.
April 26, 2012
Hey Chris, I did some checking on your question and the one-size version of the Grivel G12 Crampon will fit Euro size 36-47 shoes which converts to a US size range of size 3 to 14 so you should be all set with the one-size version. I hope this answer helps.
May 17, 2012
I believe that will actually be more like 6-13 in US sizes, European sizes have smaller increments to allow for more sizes. Hope this helps.

Which style G12 would work with Hanwag Omega boots - Cheers.
December 16, 2011
From the picture shown here, the Hanwag Omega has a sole that will accept fully automatic crampons. Meaning the heel and toe both have welts to accept the crampon. So, any model Grivel G12 would work: Cramp-O-Matic, New-Classic or the New-Matic. As far as which would be the best fit, I can't say, as I've never used this combination. I hope this helps.
December 17, 2011
Thank you, Jeff!
December 18, 2011
i would agree with jeff, all would work. I would absolutely recommend you get the cram o matic or the new matic. They are much more solid binding systems
December 23, 2011
Thank you as well, Marcello.Once again, appreciate all the help.
June 26, 2011
Why are there different points in the pics...
Why are there different points in the pics of the crampomatic, new classic, and new matic? Are the latter two 12 pt crampons, or not? Also, do all versions come with abs plates?
June 26, 2011
All of them have 12 points, the only difference is the attachment system. Grivel includes Antibott plates with all its crampons, so I'm assuming they all come like that from Backcountry (I got the New-Matics and they were included).
September 7, 2011
The images are all mixed up. The crampon body looks like the Cramp-O-Matic image. The New-Classic image is an older version of the G12 crampon. The New-Matic image looks like an older version of the G10 crampon.

I am planning to climb the Matterhorn (Hörnli) with my wife in September. We have La Sportiva Nepal Evo an La Sportiva Trango Prime boots. Do you think these will work?
Gustavo A P.
February 18, 2011
Any of the three crampons you asked about will work with the two boots you've listed. The Grivel G12 is lighter than both the BD Pro and Clip Sabertooth, but sort of has two less points. This will give you less traction, but depending on the route, might not matter at all. I prefer the wire bail attachment system myself, but the BD clip sabertooth will work on other boots without welts in the front and back (like a light hiking boot).
May 20, 2011
yes easily..but there are lighter crampons.

you wil most definitely need the extender bar,I have plastic doubles at 11.5 and they are at the very last click, again you will need it. Hope this helps.

I am interested in the G12 for use on a fairly stiff snowboard boot (Burton Ion). I have headr that they fit well onto most lower-profiled snowboarding boots, but was wondering which attachment system would be best suited to snowboarding boots? Does anyone have nay experience with this, or for that matter, any other crampons in conjunction with snowboard boots?
December 5, 2010
you can only use one kind of binding, since your boots don't have crampon welts.you can use the new classic binding, you can cross glaciers and go up steep mountains but no ice climbing
October 10, 2010

relating to Chris's question... if these are compatible with tele boots, which binding system in particular would be most compatible? hoping that the crampomatic step in system will work...
January 5, 2011
I think you can only use the cramp o matic, the new matic strap would get in they way, the cramp o matic I think would ,again, work the best
September 28, 2010
How about with tele boots?
How about with tele boots?
November 19, 2011
I have the G12 New-matic and the don't fit on my old Scarpa T2s. I can't speak for the Crampomatic. I think that Grivel makes a wide version that might work with tele boots. By the way the G12 is still an amazing crampon and I wear it whenever I'm not in tele boots.
