I dunno about the chrome...the later Treviso's are the only ones that I know had no chrome, but it could be a mid-year change, or maybe someone stripped the chrome and painted the stay or something.
it is not quite my size either, and I don't have anything larger to trade...it is certainly worth saving, though. It is my contention that there just weren't any bad pinarellos... least I've never ridden one.
