First, sorry for the lack of pics.. yet.
I bought a 1984 Trek 660 a few months back, and have slowly been piecing it together (non-original). I finally realized yesterday that I have pretty much everything, in a kind of mismatch way. It's mostly 8 speed 105 with down tube shifters. This is my first bike with downtube shifters, as STI was the requirement for my first road bike 10 years ago.
I have to say WOW! Downtube shifters shift so quickly, with such light action, I'm amazed that I've waited this long. I love the ride of this bike, though my rear is quite used to a Selle italia SLR, so I'm not sure how the B17 is going to work out in the long run.
Pics to follow soon!
