If you're familiar with Yoshiaki Nagasawa, you know he built arguably the best NJS certified frames in the world. But while 99.9% of his frames are regulated to strict NJS specifications, he briefly experimented with non NJS tubes and geometry. This road frame (serial number 01) is built with light and stiff Columbus Foco tubing, and has an aggressive geometry much like his track bikes. This was a one off frameset, custom built for a national champion Kerrin racer. Yoshiaki briefly experimented with other aero tube-sets. This frameset is 1/1 and the only Nagasawa not using traditional round tubes. TT: 54cm ST: 55cm Thanks for looking!
