Thanks for this wonderful site.
The frame was built by Mr. Fiorentino Bello, who is an Italian immigrant that come to Brazil 60 years ago. He has a bike shop at Socorro neighborhood in São Paulo, SP.
He used Columbus Cromor tubes (NOS) and the frame weights 1960 grams (54 c-to-c) with the overbuilt Nash Lugs from Ceeway (UK) - 74 degrees. It has track ends from Victoire Cycles (France), that was TIG welded a dérailleu= r hanger, so I can used it as fixie or a geared bike. The fork is a Benotto NOS purchased at eBay.
The main parts are:
Front hub: Campagnolo C-Record; Rear hub: IRO; Rims: Mavic Open SUP CD; Crankset: Campagnolo Record Pista 165mm; Chainring: Sugino Royale 44T (3/32"); Track Cog: Surly 18T (3/32"); Pedals/Straps: Campagnolo Chorus Aero; Headset: Campagnolo Chorus; Seatpost: Campagnolo Record Aero (27.2mm); Saddle: Selle Italia Turbo Pro Team Indurain; Front Brake: Campagnolo Chorus; Brake Lever: Dirty Harry; Stem: 3TTT Record 84; Handlebar: Azonic Double Wall (48 cm).
Thanks and Regards,
São Paulo - Brazil
