New one on me, I thought all the classic Campy cranks used 15mm head bolts, while Stronglight and Zeus used 16mm and the mid to lower priced Japanese cranks used 14mm. Makes me suspect someone changed the crank bolts. Bolt heads which are not metric or SAE makes one think they might be Whitworth, but I have no idea what Whitworth bolts would be doing on a Campy crank.

Im posting this question for a friend but also for my own knowledge. What size crankbolt heads has campy used throughout the years . I typically use the peanut butter wrench but this guy says he has a crank bolt with a head that none of his tools fit. He says he has gone through the range of metric and even attemted to see if any standard sockets would fit. Any odd half sizes perhaps.

Still looking for any info on the french bike I posted yesterday, Ive been told a few times that its probably a Motobecane. Anybody have links to old catalogs by chance.

Thanks again
