Proprietary Zunow tubes from Tange. Seat tube is called 'horn system' for its transition round to oval at the bottom bracket. 'Ditchex' for the top tube linear gutter that stiffens and also partially tucks in the cable. 'Pentagla' chain stay for its five sided taper. Interesting he used Italian Columbus dropouts and fork ends. The lugs are very attractive, especially the bb shell.
nice bike! The frame looks/sounds like the spitting image of my Z1, which has the pentaglia, the ditchex etc... does yours have the biplane brake bridge, too?
