I wasn't questioning its authenticity. It has the ring of truth about it for me, but I think it would be interesting to research its history a bit more and find out how it relates to how IF got under way. My guess is it's most likely made out of True Temper and it looks pretty much like a 1994 Yo Eddy aside from the cable routing. We've established that it has the same 9cm head tube as an S/M Yo Eddy (or Buckshaver), and it looks as though it has a similar 15.5" c-c seat tube, so if it has a 22.5" top tube as well, then you've got pretty much a full set of Fat Chance dimensions. From your report, it sounds as though it rides more like a Buckshaver than a Yo Eddy, but that's why you like it I guess.
