Columbus Spirit Keirin is a highly specific tubing set created for one of the most iconic worlds in steel framebuilding, the Japanese Keirin track bicycle. Built around traditional diameters and proportions, it gives framebuilders a precise starting point for track frames, fixed gear bicycles and special projects inspired by NJS racing culture.

Made in Italy from Columbus’ proprietary high-performance OMNICROM Cromoly steel alloy, Spirit Keirin combines the mechanical refinement of the Spirit family with tube dimensions suited to classic track construction. It is a tubeset for builders who want a frame with sharp handling, compact proportions and the unmistakable character of a dedicated steel track bicycle.

The Keirin discipline has always been closely connected to strict technical standards and a very particular framebuilding culture. In this context, tubing selection is not only a matter of performance, but also of tradition, proportion and compliance with a well-defined construction language. Spirit Keirin reflects that world, offering a Columbus solution for builders working on authentic track frames or distinctive fixed gear projects.

Compared to modern oversized road tubesets, Spirit Keirin follows a much more focused path. Its traditional round profiles make it especially suitable for lugged or fillet brazed construction, where the frame’s proportions, clearances and details are part of the project’s identity. For builders looking to create a special fixed gear bicycle with real framebuilding substance, this series offers something far more meaningful than a generic track tubeset.

This pre-configured Spirit Keirin 7 tubes set follows the standard Columbus selection for the Spirit Keirin series. At Cicli Corsa, we selected it for framebuilders who want to work with a technically refined, historically relevant and visually iconic platform, whether the goal is a race-oriented track frame or a unique urban fixed gear build.

Spirit Keirin can be paired with traditional head tubes, steel fork blades and 1” fork steerers, available on this website.
