bru please post some pics of your bike. while your frame may have the same decal as that Axis the frames are different. most all Bianchis from that period had that decal indicating the tubing was propriatery to Bianchi. what color is your Volpe? the Volpe had XCE for '89 / '90. the color, decals and cable routing wil determine the year. to the best of my knowledge all Volpes were made in the orient somewhere.
H9A70571. H9A4986 sort of close only about 65000 off.
