Oh, exactly how many years have you owned that bike and how many miles/km?
I maybe a nut where it concerns bolts, but on disassembly decades ago there must have been something wrong with the original bolts as it's not my habit to bin parts that can be reused. On the contrary: I've made it a sport to reuse as much original parts as possible. To give you an idea: it was not before this last summer, after 46 years and numerous, numerous adjustments, that I've renewed the 8mm lock nuts of the drive chain adjusters when they finally had become all too round. Clearly I have made the wrong decision to use ordinary bolts which I happened to have at hand. Why adding a nut would be 'asking for trouble' is not clear to me.
