Just scored one of these at the Madison swap meet. And OOOHHH la la, I think I like it.

Full 531, full first-year Shimano 105. Didn't have original wheels on it, but the wheels that it *does* have are Rigida red-label on UI Shimano hubs. For the cognoscenti, which Shimano units had oil ports and low flanges? But I *also* got a pair of Cyclone hubs inside Mavic GP3 tubies, and I think those will have to make their way on. Along with the 13-24 Sachs 7-speed freewheel.

I love swap meets. I really do.
