I have an old steel frame of unknown origin, it has a "Fangio" sticker on the seat tube, and a serial number on the headtube. Its got very tight clearances on the rear, even with a 700c, but the forks have a very long rake, and hence large clearances. It has no brazeons at all, but has long forward facing dropouts. Paintwork looks original, so I think it has original forks. In other words, I have no idea what purpose the frame was built for.
On to my problem....
The dropouts are spaced 120mm, so I had no problem sliding in a rear track wheel for a 42mm chainline.
I purchased a Stronglight Track 2000 crankset, which claims to give a 42mm chainline with a 107 bb.
Trouble is, when I hold the crankset against the bb shell, in line with the rear sprocket, the spider does not clear the chainstay. It seems like I would require more like a 110 bb.
So it appears that my options are:
Any thoughts?
