Columbus SL niobium is re-edition of the legendary SL tube set. Top tube is standard diameter 25,4 mm, 28,6 mm is the diameter of down tube and seat-tube. Steel is the material that was first used in the construction of top-of-the-range frames because of its superior mechanical characteristics, most notably its superior fatigue resistance and a breaking load second only to that of advanced composite materials. Columbus research has always worked towards the customization and development of materials with characteristics intended for cycling use. The results are of international importance.

Columbus’s history is the creation of steels with patented formulations such as the famous Nivacrom.
