CRC seem to be out of these, so wondered if anyone had some they don't need. just trying to build up a new frame and this is the only bit I don't have!
It's this that I need: http://www.chainreactioncycles.com/Models.aspx?ModelID=17423
"Shimano Front Mech Clamp Deore/LX/XT An adapter that allows the fitting of a large band front derailleur to a smaller seat tube size. Easy to fit ! Compatible with: M510/511, M530/531, M580/581, M760/761"
I also have a 34.9-31.8 adapter if anyone fancies a swap.
