Yoshiaki Nagasawa is a Japanese bicycle frame builder who builds primarily Keirin track racing bicycles. He has a one-man shop near Osaka, Japan. He studied building under Ugo De Rosa of De Rosa Bicycles, and has been building bicycles in Japan since the late 1970s. Notable riders of his bikes include Koichi Nakano.

The cycling industry is increasingly driven by mass production and the latest materials.But some are still building bicycles the old fashioned way.Yoshiaki Nagasawa trained in Italy and says that his bikes are just as strong as they are beautiful even though they are not made of aluminum or carbon fibre.
