That's nothing compared to the fun you can have with Stronglight cranks. Several models, including the the mod 99, and I think the mod 104 and mod 105, spanned the transition in the early 80's from 23.35 mm Stronglight extractor thread to now standard 22 mm thread. Plus the same models were available with either French or English pedal thread. So you might get a used crankset with a 23.35 right arm with French pedal thread and a 22 mm left arm with English pedal thread. And for even more fun, maybe someone lost one of the original 16 mm crank bolts and replaced it with a 15 mm Campy bolt.
That would mean that for the same crankset, you might need two different crank extractors, two different type dustcaps, two different peanut butter wrenches, and pedals with two different threadings. Of course this sort of thing doesn't happen with an NOS crank, but it's quite common to buy used cranks in which the two arms came from different original cranksets.
Ain't French stuff wonderful?

I think it was Tom Dalton who remarked that Campy crank bolts also came in 14mm size, too. I have found vintage bikes with 14mm on the non-drive side and 15mm on the drive side. I really can't imagine why, but I have. Possibly to keep constant the rule that if I get a pocket full of tools out of one of my boxes instead of carrying the box out on the patio or to wherever the bike is, I'll invariably have the wrong tool or need one (or more) more and have to make at least one additional trip back to the box...sort of a Murphy's law, I guess. Now here is a question for the cognoscenti...Did Campy make anything but a 15mm peanut butter wrench? Tom Sanders Lansing, Mi
