- Three available attachment systems let you pick the perfect 'poons for your boots
- Anti-balling plates keep snow from sticking to the bottom
- Tool-free length adjustment
- Item #GRV0050

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.
- Familiarity: I've used it once or twice and have initial impressions
These are perfect so far. Easy to get on and size. Hold in the ice well.
Easy and solid.
- Familiarity: I've used it once or twice and have initial impressions
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.

I still love lighter crampons for skiing and approaches, but when rock and ice mix or long sections of ice appear on alpine routes, these are a good choice. Very durable, strong attachment, and decent price. I don't love frontpointing in them but they do the job just fine, and if you keep a pair of extended bars around they make a good no-fuss loaner pon. Plus the G12s hold their value better than most other crampons, so you can always upgrade with not too much loss.
Cramp o matic system
- Familiarity: I've used it several times
I've used those crampons with my koflach degree boots and they stay solidly in place. I've used them mainly on Rainier and Baker, and they've done the job. They are pretty solid, walking on rocks and ice. My only dissapointment is the top lever part in front will break, it seems pretty flimsy.
Not Long enough for Scarpa Inverno 13
Awesome crampons! Only problem - and it is a real problem - when I used my Scarpa Charmox Size 46 with it, no problem, it'll fit. when I used my Scarpa Inverno double boots size 13 with it, it will not fit. I was at Mt. Rainier (Ashford, WA) and I had to run to Whittaker Mountaineering Store to buy the long extended bar, and even with the long bar, it barely fits. Size 13 double boots is not extremely large, so becareful guys.
The crampons work no problem.
These are awesome! I got them with the new matic binding system, and they work flawlessly! Easily adjustable!
Great place to start
These were my first pair of crampons, got them many years ago in the "new classic" style, strapped them to a pair of leather hiking boots and they were good to go. Did some winter mountaineering, climbed Shasta in them, and eventually had them out on WI2-3 ice. Great for all of these. Mine came with the anti-balling plates, and I never had any issues with snow building up. Easy to adjust, minimal maintenance. Perfect for what they are designed for.
All around good
This is not the best vertical crampon on the market but it is a pretty solid universal crampon. With 12 points you are guaranteed some traction at almost any angle. I use these when i am doing a lot of mixed mountaineering, never anything vertical, for that I use BD Cyborg's, Grivel Rambo's or Grivel 14. I like these a lot and usually bring these on gen mt. trips.
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
Stick to the ice
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.
This crampon is awesome! Ive used it on both vertical ice as well as some mixed alpine terrain and they performed beautifully. I prefer the horizontal front points to the vertical and sometimes its hard to find a crampon with this many points that have horizontal points...this one, obviously, does and its perfect! If you are looking for a crampon to be able to use for anything from glacier travel to steep angled ice, this is your product!
Pretty awesome crampons. These are very durable and fit my Scarpa Mont Blancs well. In retrospect I wish I had gone with the traditional wire bail over the "new-matic" style as it offers just a little more ability to adjust the position of the frontpoints.
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.
G12 on water ice
G12 on mixed
G12 on M6...awesome chromoly crampons
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?
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!
what size would recommend for size 9 snowboard boot?
They're one size and with a size 9 boot you will not need the longer center bar. The wide version will fit better!
Which attachment system would be best with AT boots? I am guessing the cramp-o-matic.
You have guessed correctly! The Cramp-O-Matic is the most secure fit to your AT Boots.

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??
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.

Do the XL Cramp-O-Matic's already have the extended bar and are they wider than the non-XL version?

Will these fit an AT ski boot such as the Salomon Quest 12?
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.
...although they will if you get the longbar.

Is the New Matic photo ok? I think it is a G10 new matic crampon, it not have 12 points.
The Newmatic pic is a G10, but I've never seen that front binding before.
Thanks Pat, hope Backcountry fix the problem.
Hi, Just looking at the Grivel G12 with...
Just looking at the Grivel G12 with the Cramp-O-Matic front bail. Question: What size range boots is the XL version designed for?
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.

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.
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.
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.
Hi ! I have Telemark NTN system and Scarpa...
I have Telemark NTN system and Scarpa TX Pro boot.
I need to know wich crampons is the best for this boot.
Im shure someone out there has a good tip, wether this Grivel or another Grivel crampons is the best.
I think you probably want to go with a toe strap crampon instead of clip. My buddy has used his T1 with a strap crampon and it worked pretty well. I would go with the Petzl Lynx if you want to be able to do strap or clip. Hope this helps.
Thx for reply !
My problem is that I live in Norway, and Petzl is on the list for no export to here, and I also looked into Grivel products, seems quite good.
Maybe, I should look for a Grivel one with strap, gives more flex.. comparing to the boots .
I'd look into an alu crampon or lighter one for tele boots. With ski boots crampons are likely on your back more than your boots, and the G12s are really designed for mountaineering. Airtech lights arent too bad
Which style G12 would work with Hanwag...
Which style G12 would work with Hanwag Omega boots - Cheers.
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.
Thank you, Jeff!
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
Thank you as well, Marcello.Once again, appreciate all the help.
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?
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).
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...
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?
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).
yes easily..but there are lighter crampons.
Will the new-matics fit on the La Sportiva...
Will the new-matics fit on the La Sportiva Glacier boot or is it better to use the new classic?
new-matic, they are more reliable, stronger and will hold much better

Im trying to figure out if I can use these with my size US 13.5 Koflach Degree (http://www.trailspace.com/gear/koflach/degre/)
Or do I need to get the XL ones? Thanks!
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?
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

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...
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
How about with tele boots?
How about with tele boots?
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.
The Grivel site says these are "easily...
The Grivel site says these are "easily folded for transportation." What does this mean exactly?
Simply, they are easily collapsed or adjusted when packing and un-packing.
More specifically, the front section can slide back along the bar towards the heel section so the crampon gets shorter. On the other hand the front basket is rather stiff and cannot be easily folded.
They are not easily folded and a PIA to pack. Good crampon none the less.
I'm thinking about getting the new-classics....
I'm thinking about getting the new-classics. I am interested in getting a pair of crampons that will work well for double boots as well as my regular hiking boots (LL bean Cresta Hikers) will these work/fit alright with my Cresta hikers?
They would work fine for both, but be super careful about using these on regular hiking boots with soft soles.
Its very easy to get yourself over your head going up something that you won't have the performance of stiff boots to safely get down.
The strap binding isn't really that much more difficult to put on but its harder to be certain that you have a good connection whereas the newmatic feels a little more secure and is easier to verify.
Of course if you plan on using these with hiking boots occasionally you can only get the new classic (strap version).
