Hi all! I need a set of take-off slicks for an old race bike. I'm afraid this one is just to old and beat to ever be ridden again but I need a set of tires to hold it up off the garage floor! 180-17 rear and 120-17 front, if someone had a set of old Michelins gathering dust that would be exceptional but anything round, black and that holds air for a while will do.
