6 cogs on the freewheel. again nice looking Bianchi. as I said earlier I think it is an '86 frame that someone bought and then built with the dur ace components. non of the cataloged bikes in '86 or '87 had chromed forks so that is why I think it was a frame only build up. the catalog just says 'Bianchi' for the dropouts.
Formula One tubing was only used for two frames in '86 the it was dropped. Bianchi used to do alot of 'grassroots' sponsorship so perhaps this is a frame that came from that avenue
