Bars and stem are from 80s mtbs, Specialized stem and straight bar from one bike, riser bar(unmarked) from another. Where the grips and levers were, brake and thumb, the ano is now black in the exact same areas covered. Furthermore, the Specialized stem(black where inserted) and bar exhibit a fade pattern, from the original ano to a bronze color, on their underside(protected from the sun). Weird! I'm looking forward to enlightenment.
