Description

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. A removable heel spur gives 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.

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.

these are the stiffest crampons ive used. I have sabretooths, petzl sarkens and have used cyborgs. These are the stiffest and seem to penetrate the ice the best. Mono points are the best in my opinion and i have never climbed with these in dual points. They are easy to adjust and I like the anti ball plates. I dont mind walking in them for short distances, but I wouldnt want to go up rainier in them.

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.

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.

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.
