water ice climbing crampon equivalent to the current Grivel Rambo 4 crampon (retails @ $220,or, that's the cheapest I've seen on the web): grivel.com/products/rambo-4  

This pair comes with a dual point conversion kit it you'd rather switch back to old school (better for rotten ice?)  Main advantage or disadvantage on these is they're 100 grams lighter than the current Rambo 4s since they don't have the anti-balling plates.  No idea why one would really need the latter on steep technical ice. Fully adjustable via allen key wretches.  Can also change articulation on aspects of the crampon.

Good condition as denoted in pictures.  Note limited paint wear = limited use.
