One would think that crankset was introduced for the 1987 model year, when Shimano reintroduced Deore as a dedicated ATB group (i.e. MT60 series). However my 1987 literature only shows derailleurs,...

I neglected to mention how much I like the Ed Litton. It certainly doesn't hurt that the livery is reminiscent of a mid-1980s Team Miyata. Nice choice. Enjoy!
