I tried this once before and was told to try again. I'm new to the forum so I'm still finding my way around. I'm not sure if I am supposed to start a new thread or if I can ask my question on this thread. Nothing ventured, nothing gained.
I bought a Bianchi Columbus SLX at an estate sale a couple of years ago with the idea of restoring it. I have since changed my mind 1. because the bike is a bit too large for me and 2. I'm not sure I could restore it properly. It has a fair amount of rust but I think most of it would come off easily and completely when sanded to metal. That said I'm trying to find out what I bought. It appears the bike was manufactured in Japan based on all the Japanese parts on the bike. Here's the dope on the bike:
Bianchi Columbus SLX
Serial #: 117121
Derailleurs: Shimano Altus LT
Sprocket: Sugino 52
Rear rim: Araya with Schuller hub (made in France) ????
Front rim: Araya with Sekai hub
