I finished restoring this 3Rensho recently, and just got some high-res pictures to share. I only know a little bit of its history, and am hoping the good folks here at Bikeforums can help me validate what I do know, and add as much of the back-story as possible or connect me with individuals who could. I wrote up a full article on my blog, which you can read here:

What I do know:
- The BB shell is stamped "CHAMPION" indicating that it, and likely the rest of the bike, are made of Tange Champion tubing.
- The Suntour Superbe groupset is original to the bike, as are the Dia-Compe Royal Gran Compe brakes
What I *think* I know:
- It was a one-off custom for a USA (possibly NYC) bike show in the late 70s
- It was made during the time that Yoshi Konno was transitioning from his original Cyclone brand to the 3Rensho brand
- It was made by Konno himself
I plan to reach out to Andry Muzi of YellowJersey today. If anyone has more info, or can introduce me to someone who does, please let me know! I would love to establish the factual history of this unique and lovely bicycle.
