I really have a thing for steel track frames. Steel is a fantastic medium of expression for the artistry of framebuilding. And I have very specific tastes. You can search the net and find whole sites dedicated to œold skool track bikes preferably lugged steel. Even more, there is definitely a cult surrounding keirin frames from Japan. However, I grew up in the Eighties when framebuilders were making crazy machines out of fillet-brazed steel for the track sprinters of that era. I especially liked those match-sprint 3Renshos and the bikes of East Germans.
Back then steel tubing was generally round and as double-butted tubing came in a limited number of diameters. These days one can get all kinds of steel tubing with shaped cross-sections and various butting profiles. I handpicked every tube for my bike, going for maximum stiffness with little regard for weight.
