Long storey, but I have to take apart my E10 frame to repaint it and replace all the bearings. One of the chain stay pivot bolts will not undo. The ’nut’ which is only 6mm thick and has a bevelled top, only has two flats opposite each other and is partially encapsulated in the chain stay but it no longer holds in place and spins when I turn the bolt. I have tried various methods of trying to stop it spinning but nothing seems to work, so I may have to cut or drill off the ‘nut’ if I do so, I will have to source replacements. Does anyone know where I can get replacements bolts ant ‘nut’ from? Thanks.
