A co-worker has a Bianchi roadbike, doesn't know what model the bike is. He got it as a frameset and repainted it several/many years ago and put on a Bianchi decal set he got from somewhere. Rear spacing is 126mm and the frame is about 62cm ctc.

There is a number on the bottom bracket: CS26952.

Any idea what year it might be from? Also, what specific details should I look at to help identify it further?

And, sorry, no pics yet. I'll post some if/when I can.

Thanks for any input. He currently has it built up with a mix of parts, 6 speed on back, triple on front, Campy hubs, tubular rims, SunTour shifter arms on the downtube, Shimano derailleurs, 3TTT stem, whatever he could find at the time to make it ridable.
