These are the bars that come with the Grivel brand crampons. They are the standard size and will work with the Grivel G10/G12/G14/Air Tech models. If you have the regular hard bars these may be a nice replacement for those or for a broken set. They are brand new, never used.
I had to order the long bars for a new pair of G10's due to a large shoe size. I will sell them for $15 shipped with confirmation if anyone is interested.
I'll include the instructions that came with the long set if you want.
