Hi, I bought a peugeot concorde bike off ebay a while back, and have been slowly upgrading everything with a view to make it a single speed. Many problems have ensued (namely with the wheels, and the seemingly unremovable freewheel at the back), but the probelm I am having now is with the bottom bracket.
The cranks are held in with cotter pins that just won't come out, so I have accepted that I might have to saw off the whole thing and replace it. I have some campagnolo veloce cranks, but am not sure if there is a bottom bracket compatible with this combination. I'm not a bike genius, but understand there are different threads for BBs, and that french ones seem to be a little awkward.
The bike shops I've been to don't really have any suggestions other than cutting them off and seeing. I just don't want to cut them off and find they can't be replaced, or buy one that I think will fit but won't.
I have attached some images, if there are other I could take that would be more helpful then let me know.
Either way, I want a new bottom bracket and chainset, so can anyone help me identify what kind of one I need for this bike, if it is replaceable? Any help would be much appreciated,
