Can anyone say what frame tubing a Bianchi Nuava Racing 12/V frameset is made of. This bike is circa '83 based on the NR rear der. It is a mid-level racing bike with Ofmega components. 27.2 seatpost, B engraved in fork crown, Celeste, Bianchi dropouts, eyelets. Light at 22.5 pounds with clinchers but no tubing decals at all. Also the brakes were changed. Anyone know the originals?
