Hey all, so I found a deal on a NOS Alan Aluminum frame. Seems really nice. I did some research and evidently Alan (an Italian manufacturer) pioneered a system of gluing aluminum tubing into bracket to form the frame. I guess it didn't work out. The frame I'm looking at is welded using 7020 aluminum, which we don't see very much. Anyone have any info or experience with this sort of Alan frame? Thank you!
