I'm not a 3Rensho/Yoshi Konno expert but I'm thoroughly obsessed, have done a ton of research and own many 3Rensho and several other Yoshi Konno built frames (Specialized Allez's).

Based on the awful pictures available, I'm fairly sure it's an authentic 3Rensho frame, it's a repaint, it's been modified and the fork is probably not original.

Details that point to it being a 3Rensho include the fastback seat stay arrangement as well as the aero shape to the stays, and shifter placement.

Definitely a repaint, not an original color, it's been modified with internal brake cable routing, decal placement is way off. Fork crown shape is off and there appears to possibly be a line running around the top of the fork blade which to me points to a possible aluminum fork, which is definitely not original. Scott made aluminum forks right?


Here's a 3Rensho I owned a while back for reference, lots of good detail shots.

With a mix of what appears to be Shimano 105 and Dura Ace, the bad repaint and modification to the frame, and possible non-original fork, I'd be hard pressed to pay anything more than $300-350. If the fork turns out to be original, I'd fork over $600 tops.
