"Mr Yoshi Konno began his building career by unbrazing Cinellis acquired after the 1964 Tokyo Olympics. HIs accomplished college 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 famous customers include Koichi Nakano (most of whose frames were Nagasawas), Dave Grylls (Pan Am gold medal), Gibby Hatton, Dave Harrington, Bob Mionske (4th at Seoul Olympics, US National Road Champion), Dan Casebeer (US Hour record). Mr Konno was paralyzed in a car crash and there will be no more 3Renshos."
