I'm kind of doubting it's what it's claimed. a few things i've noticed that are different from the my 3rensho aerodynamics.
the seat cluster is similar but the binder bolt on the ebay bike is up higher, where as mine is right through the stays.
it doesn't appear to have the "superend" stays either on the fork tips or the rear drop-out. though the pic isn't very good, mine are stamped "superends" on the the drop-out and if you look closely at the picture of the ebay forks, you can't see a "lug" around the tip in the background.
and as David Ross mentioned "the headtube ring portion of the head lugs (on the auction frame) have an interesting taper, decreasing in height at the front of the headtube. Mine is more conventional." mine is also like David's.
also the shape of the fork is "different". the ebay bike's fork looks "beefier".
about the only thing 3rensho like, is the chainstay bridge behind the bottom bracket.
this are just my observations. here are pics of my 3rensho aerodynamics.
