i tried to indentify by paint, but it's a bit confusing. the stripes on the toptube and seattube look like the 89 carbon pro. all teh bikes before i think 87 or 88 dont have a fade paint job, and have dots or something on either side of the logo on the downtube. but all the 88's and 89's that are faded fade all the way out to the bottom, not jsut where the logo is.
