Awesome '87 swchinn prologue made of tange tubing. This is when schwinn was making some pretty fine bikes and the prologue is one step below the paramount, making it a good quality race bike from the late '80s. I hooked it up on the cheap but its totally decent. Mostly original shimano 600 parts with a dura ace rear deraileur, fizik saddle, random front wheel and technomic to short and shallow bars. I love this ride, complete with 6 speeds and downtube shifters.
