I have owned this bike since new, ridden and loved it lots. A few components have been replaced but only in keeping with the spirit of the original. The stem is a longer steel quill from the same time period. Crank, chainrings and bottom bracket are replaced but the originals are still here. The main items that make it Grant Peterson's favorite are still there: steel frame, ritchey rims, suntour accushift drivetrain (in perfect shifting order), Dia-compe brakes, open pedals with steel toeclips, etc. Heck, I even have the original owner's manual. Any idea what it might be worth?
