ABH, thanks for posting. It's definitely a 1986 model, manufactured early in that year. The only thing that is out of place are the Exage levers. Maybe there was shortage?Not sure what the 59 on the cranks means. The Shimano date codes consist of two letters. Given the vintage of the frame, I would expect something starting with a "J" (1985) or "K" (1986). The second letter is the month, where A = Jan., B = Feb., etc.
