Mr Yoshi Konno began his building career by unbrazing Cinellis acquired after the 1964 Tokyo Olympics. His accomplished collegiate cycling career
brought him initial notice in the cycling community. He remained a formidable cyclist through middle age, completing a quick double century on his 40th birthday. His bicycles where ridden and won many Olympic Cycling competitions. Riders included;
Koichi Nakano (most of whose
frames were Nagasawas),
Dave Grylls (Pan Am gold medal),
Gibby Hatton, Dave Harrington, Bob Mionske (4th at Seoul Olympics,
12th at Barcelona Olympics, US National Road Champion), Dan
Casebeer (US Hour record) and Greg Meeker. Unfortunately Yoshi Konno career was cut short when he was paralyzed in a automobile accident. Sadly the 3Rensho bicycle company shortly after stopped producing frames.
