Samson

Some real Keirin frame pr*n here. Incredibly nice looking Samson 54cm frame, Columbus tubing with neat details like the aero fastback seat stays and all. 

According to some sources Harada-san, who builds Samson frames, is currently considered as one of the top Japanese, if not the top, framebuilder by the Keirin pros in Japan. Gaijin hipsters might dig 3Renshos, Nagasawas, Makinos and Kalavinkas but it's a different game over there. Samson frames are apparently also the most expensive Keirin frames to get built. 

But hey, in case you didn't already notice, it's for sale NOW in here.
