But you guys are right about it being light. This bike weighs only ounces less than my Marinoni.
The later Apollos like yours seem to have had their own tubing decals, whereas the earlier ones in the same place in the model lineup, used Tange tubes. Whether or not the tubing actually was Kuwahara's own is something I can't answer.
Furthermore, it is interesting that the better Apollos of the late '70s / early '80s used Kuwahara dropouts even though the tubing was Tange.
