I recently acquired an unidentified bike on Craigslist. The BB fixed cup is marked 'Campanolo con sfere DA 3/16" ', and the spindle is marked '32-RN' on one of the flats. The spindle is otherwise unmarked. The threading is English. I believe the crankset is a Stronglight model 57. What is the meaning of the markings on the cup and the spindle flat?
Thanks for any help...
