Picked this up on Saturday. I believe it is a 1988 or 89. From what I can tell I think it is in the Quantum series. It has a complete 1988 Shimano 600/Ultegra group on it. The rear wheel is a Campy and the front is a Mavic. I have the bars out and the seat is a cheapo. It will clean up nice, unfortunately it is to big. I wish the top decals were not missing so I would no for sure which model it is.
