Several months ago, I bought my girlfriend a secondhand De Rosa with Columbus SLX tubing. It was built for 650c wheels and had a flat-crown steel fork. On the bottom bracket was engraved "Geronimo"; on the underside of the bottom bracket was "Wilfredo de Leon." The Os had the hearts in them.
Can anyone tell me when this frame was made? (I'm guessing mid-80s.) Was Geronimo a model? Was De Leon a framebuilder or the person for whom the bike was made?
