Hugo Koblet's Tour de France-winning bike from 1951 used cranks marked "Durax Service Course" - at least that is what the Rebour drawing in Bicycle Quarterly Vol. 2, No. 2 shows... the only info Rebour provided was that the cranks were 172 mm long. Cottered steel, no doubt, and apparently a Stronglight BB, if I interpret the drawing correctly. The originals appeared in Le Cycle, August 4, 1951.
