Here's the beef......at least the downtube. This frame has a bi-oval NOS Easton 'Rad" downtube. I think I still have about three boxes of these monsters. The wall is so thick I don't think you could dent it with a hammer unless you were really swinging it.
That said, this frame still comes in at less than 5 lbs. There are the two Ahrens yokes and rectangular stays.Other than the chainstays and headtube, this is all NOS Easton Elite. I seem to have lots of this MTB stuff still around. I'm getting really lean on road frame tubes and will now have to source some other stuff after this 11 frame batch.
