I suppose I cant resist posting to this thread, due to the color scheme on my ride. The bike does fit the bill due to the fact that this would likely be a rivendale if I had more disposable income. Now, If only I could find a cheap 80s frame with the double top tube.... This is near as I'll get I suppose.
It is a 68cm 1987 Nishiki Sport. Straight gauge 4130 CroMo. The frame itself is 8 pounds, and the entire bike is 32 pounds with the internal hub. It is smooth and very steady at speed (have had it up to 40mph).
I am currently experimenting with a very "small" setup to see if I could swing a 64cm frame. With the seat and bars where they are, they are about where they would be on a 64cm frame. They fit, though at the low end of what I think is comfortable. (I am 6'7")
