I thinking on buying this very lightweight track frame that is very similar in looks to those beautiful takhion pursuit frames from the urss 80's. I was told that brazilian cycling federation bought four of those frames in the late 90's for competing at a Pan Am and that's it, no more relevant info. The guy who holds the frame believed for some mysterious idea that this was a colnago frame and to me it makes absolute no sense since i've never heard of italian frames with similar geometry. My guess is south american, but I don't believe the italian threaded bb would match.
It is a 26.8mm seatpost and i could not find anything stamped on the dropouts neither on the bottom bracket or fork. Any ideas?
