I have the exact same bike and have been riding it since 1982. My bike (also blue) has been through a lot over the years. One summer I had locked it up on a narrow street in the North End of Boston and when I came out from a nice Italian meal, my top tube was bent in, in the middle of the tube, though still straight. Eventually, I had that section fixed. I also changed out the original stock Suntour derailleurs and replaced them with Campagnolo parts. I also put some better wheels on them and put on a tighter (gearing) freewheel (sprocket set). I agree with the previous posting about the Reynolds 531 tubing (being fairly light), which was (maybe still is) considered very good. Oh, and Trek was still making their bikes in Wisconsin at that time. The only thing I wish is that the wheelbase was a bit tighter, i.e. the front fork has too much of an angle for me, but I guess it is meant for touring as you will notice soldered on lugs on the front and back of the frame... great for those Blackburn racks. Ah, time for an over-haul. Cheers! - Mike
