Hello all: I am in the process of rescuing this Bianchi from neglect, and wondered if the accumulated wisdom of the forum can help me identify the model. It appears to be from the '80s, and is equipped with what looks like a full Triomphe group. I am not sure if they are the original parts.
The frame looks a lot like ones I have seen in a 1984 catalogue: polished chrome for lugs with a pantographed "B", pantographed "B" on the downtube/head tube lug, "B" in a circle on the end of the polished chrome seatstay spears. (In fact, the whole frame appears to be chrome beneath the celeste paint.) The bottom bracket shelf has three slot cutouts, the rear dropouts are Campagnolo.
There is an "A" on the drive side of the seattube lug, and a 604 on the other side. Does that help?
Thanks for any assistance you can give. I am slowly returning it to working condition, and I would love to know more about the frame.
(Oh, and why does the darn headset keep coming loose? I am sure I have the bearing cup and lockring set properly!)
