/ Sportiva Nepals & G12 Crampon Problem
I have Size 42 Nepals and put some G12 Neumatic crampons on them - problem I am having is that despite an initial tight fit, when climbing the whole crampon shifts backwards, leaving but a centimeter of visible front points. Anybody else encountered this? Anybody come up with a solution?
Ended up going back to my old F2 cheese cutters....
Any advice/comment welcome...
yeah had a similar issue, but my crampons were quite old, so i just replaced them. Petzl seem to fit Sportiva boots better by all accounts and Grivel fit Scarpa boots best....
No, haven't bent them. It would appear that the front posts are too wide so that the boot slips forward/crampon slips backward. Only solution I can come up with is an old one from the days of bent tin Salewa's - a bail wire rount the front....
New Matic crampons in the smaller boot sizes such as size 5 or 6's and on boots with narrow welts such as the Scarpa Guides will often have less of the front points showing. However I wouldn't have thought it would be a major problem in size 8(42). Are the crampons and boots new or are the boots worn and have been resoled? Maybe somebody bent the front posts wider to fit ski boots?
Bend the posts in so that the crampon can't slide back......
Have a similar problem with my size 10s, but its because the front of the sole/midsole is now quite worn, ie no chance of fitting a crampon with a stainless spring wire front bail. Bending the front posts in a bit and making sure the strap is as tight as you can get it is about the best answer I found
You can replace the sliding crampon sizing mechanism with small bolts too, that makes the whole thing a bit more rigid.
