Get serious on burly ice and mixed terrain. Get the aggressive Grivel Rambo Evolution 4 Crampons.

The Grivel Rambo Evolution 4 Crampons use a monopoint design to allow precise footwork on mixed ground and a shorter secondary point to increase stability on pure ice. Combine this point configuration with a rigid frame design, and the Evolution 4 Crampons show their true colors as serious tools for technically demanding ice and mixed climbing. Add the removable heel spur (not included) to give these Grivel crampons an advantage on ultra-steep mixed terrain. This latest evolution of the always-popular Rambo crampons also includes an integrated active anti-balling system to keep snow from building and destroying your traction.

Vertical/Mixed and that's about it

  • Familiarity: I've put it through the wringer

Nice crampons for vertical/mixed projects, but with the caveat that they are pretty much restricted to that - ice cragging. The disadvantages being that they are heavy and not compact-able and while they will get you back down to level ground they do not walk well. My anti-bots haven't broken but it is a concern based on what others have experienced. I definitely like them for water ice and really like the front point configuration. It gets good penetration, is stable with the secondary points and still allows for some lateral pivoting securely. All in all a cool crampon if you can add it to a quiver. Not the best option for a single crampon. If they would tweak the anti-bots, make it lighter and collapsible, these would be my favorite crampon for sure.

Heel spur anywhere !?

Where can I find heels spurs ?

Responded on

The box comes with four points, two are 98mm and tow are 108mm. The 98mm are your mono front points and the 108mm are the heel spurs. Grivel recently changed the heel spur design, I am not sure why I liked the old angle on the blade style spur better. If you want the extra front points liberty mountain can get them for you, they are a direct Grivel dealer. I found this information by looking for the heel spurs ordering them and then receiving what I already had, but it came with a parts diagram showing the problem and explaining the confusion.

Is this the same front point as the g14?...

Is this the same front point as the g14? I want to replace my rambo front points.

It is a different point, contact Liberty Mountain for Rambo parts, they are a direct dealer and will help.

STEEP

These are badass. I use them when I am working on more vertical to inverted ice. the monopoint allows for more variable grip. There are designed well and balanced proportionately. Not for your walk in the woods,but definitely a solid crampon.

Antibots suck

I have 3 pairs of crampons - BD Sabertooths, Cyborgs, and these -- the BD brand by far beat these in just about every way aside from the heel spur in my opinion. I like the front point configuration versatility - but the durability of these crampons has so much to be desired.

1st time out, both anti-bots broke in different places. No - I was not using them improperly unless walking in snow and standing at the bottom of a climb on ice are considered improper. I was really disappointed.. Another note was the depth, or lack there of, because of the anti-bot and curved points. There is hardly any penetration when attempting to use these things on even ground (such as a rest when climbing, approach, etc.) To me, these crampons have the ultimate shiny ball effect - wow!! these are neat, get a pair, use them a little, and return or retire them and go back to your trusted and proven BD or Petzl favs.

Jeremy,
Have you read the reviews about the cyborgs and saberteeth? There are so many reports of bd crampons straight up breaking. Mid climb. Even the new stainless steel ones break away. My friends use the bd models, and both have to be manhandled with pliers often because of the shoddy adjustment wheel. Perhaps the Rambo is not the right grivel crampon for you. (Rambo is really for mixed climbing, AND THAT IS ALL). Before suggesting an inferior product I suggest you Try the grivel g-14. It can be set up for single, or dual points, they do not ball, or break, they walk just fine for a super aggressive 'pon, and they made with SOLAR ENERGY by a company that has been HOT FORGING for over 200 years. I have had to flake way too many ropes while my friends struggle with the bd crapons. Grivel simply builds better products.

Love these crampons!

I used two different dual-point crampons before buying a pair of these. I definitely won't ever go back to dual-points, and I don't think I'll be buying any other models until Grivel stops making these.

Great Crampon

I used other people's and these worked perfectly, maybe the best I've used so far.

I'm not sure how someone could down rate it because walking in it was annoying, they aren't shoes.
