In 1987 an Argentin 'commemorative' bike was available on a limited basis. It was the top of the line Bianchi for 1987-88. It is also sometimes called a Specialissima X-4 and was equipped with early Campy C-record and Campy Colbalto brakes. Columbus SLX tubing. Lots of custom engraving included the head tube emblem, fork crown, seat stays, lugs had a "B" cutout; the rear brake-bridge was engraved with an "X-4". Black chromed (or painted) head tube, fork, rear stays - Celeste everywhere else. They were not found in an y US Bianchi Catalogues, and they retailed at about $2075. Since few people know of these frames, bargains can be had!
