At the moment I only have a crappy sewing measuring tape to check but it's looking like 115mm??

They definitely will! Yours look great. The ones I'm selling are actually pretty shiny themselves, but it isn't captured so well.

Straight from the factory of Motobecane in 1972 on a Le Champion. I bought the bike the year after it was sold to the PO in original configuration.
