    Little problem with small boots

    • Familiarity: I've put it through the wringer

    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.

    Favorite all around crampon

    • Familiarity: I've used it once or twice and have initial impressions

    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

    • Familiarity: I've used it once or twice and have initial impressions

    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.

    Great for Mountaineering

    • Familiarity: I've used it several times

    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.

    Great for Mountaineering

    Great Gift!

    • Familiarity: I've used it once or twice and have initial impressions

    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."

    Climbed Orizaba in these

    • Familiarity: I've used it once or twice and have initial impressions

    .... 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

    • Familiarity: I've used it once or twice and have initial impressions

    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.

    All-arounder

    • Familiarity: I've put it through the wringer

    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.

    All-arounder

    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!

    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.

    awesome all-rounder

    • Familiarity: I've put it through the wringer

    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.

    Resistant

    • 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.

      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?

      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.

      Unanswered Question

      I need a replacement strap for my G12 new-matic. What length strap do i need to buy? I've seen a couple different sizes.

      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?

      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?

      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!

      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...

      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.

      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.

      Which style G12 would work with Hanwag...

      Which style G12 would work with Hanwag Omega boots - Cheers.

      Which style G12 would work with Hanwag...

      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.

      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).

      Best Answer

      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.
