Hello WOW nice ride! that looks like a '89 or '90 Giro with Campi Athena w/syncro? I will double check my catalog tomorrow but I think that is about right. the lugged SLX frame and decal style say those years. how does she ride? does the syncro shift well? if there is a little lever on the side you can move that and 'lock out' the index then you have friction shift. the Mavis rim is likely a replacement, especially on a frame that size 57/59?
