/ Grivel G12 Crampons - Nuts and Bolts
But what are the set of nuts and bolts used for that come with the crampons. Running Repairs????
How do you get the adjustable spring out to replace with the nut and bolt.
Really? Never had a problem with mine in 5+ years, used for everythng as well!
I think it saves a few grams as well, which if your of to K2 or something might be helpful. My spring adjusters are a bit knackered now but my G12s are over 10 years old.

Yeah, me neither - I have had a bar fracture and had to replace it, but you'd be doing that bolt or no. As I'm always going from boot to boot, I wouldn't want to bolt 'em.
For some reason I thought it had something to do with the heel clamp.
Thanks for the replies
Still not had a problem with my own or clients crampons so must be something to do with what folk are doing with the new antobots on the link bar!
Acording to grivel it's very rare but does happen.
Not seen that thread before, will be having a good inspection of mine in the morning now!
I don't use the acodrian. I've never had a crampon come apart and looking at the fit on my boots I can't see how it would do (unless I hadn't cleared the snow properly from the soles before putting them on). The cleats of my boot firmly hold the spring down and cover the pin part of the spring well too.
So you wouldn't have any issues without the acordian or with it on if the lip is over the pin clip. Chances are so slim of snow opening the clip that even without the acordian fitted properly I doubt anything would happen.
I've seen clients adjust crampons with the adjustment clip over the accordion. I have had clients force the spring-clip open, deforming the clip so that it wouldn't fit as securely. One client managed to break an ice axe and helmet adjustment straps as well as the crampons!!!
Twice I've seen the new crampons fall apart. Once top-roping an ice climb in France with a French Guide and once on a Scottish Winter course. In both cases they were novices who hadn't adjusted their crampons properly.
On more recent crampons supplied with the accordions I've never fitted the accordion onto the adjustment bar as it makes shortening the crampon when packing into a crampon bag more difficult. It's also more of a hassle to adjust dozens of hire crampons or swap them between different sized boots.
IMHO I don't see the accordions making that much more of a difference for anti snow balling, so the additional hassle outweighs any benefit.
In my experience the clips never failed prior to the accordion being supplied and it is only since they've been supplied as standard that some problems have come to light.
If it makes folk feel safer by fitting the nuts and bolt then why not do so.
I'm still happy to use the spring-clip on my own personal crampons as I swap between several different pairs of boots, but without the accordions which I don't like.
Interesting, Ron... but I'm certain I didn't make that mistake! So still don't know why mine failed, although I can see why you don't like the accordeons.
