The Columbus XCr 4 Lugs tubing set brings Columbus’ most prestigious stainless steel platform into a construction language inspired by classic handmade framebuilding. It is intended for builders who want the corrosion resistance, mechanical performance and visual refinement of XCr, while working with lug-compatible proportions and the controlled elegance of traditional steel frame design.

Made in Italy from seamless biphasic stainless steel, XCr 4 Lugs is a rare and highly technical choice for custom framebuilders. Its smooth surface finish, carefully controlled wall thicknesses and excellent weldability make it suitable for refined lugged or fillet brazed stainless steel frames, where every junction becomes part of the identity of the bicycle.

Compared to the standard XCr series, XCr 4 Lugs is aimed at projects where the construction method is not only structural, but also aesthetic. It is a tubeset for made-to-measure frames with classic lines, polished details and a more traditional visual balance, without giving up the high-end performance expected from Columbus’ top stainless steel tubing.

At Cicli Corsa, we see XCr 4 Lugs as one of the most distinctive options in the Columbus range, especially for framebuilders working on special commissions, collector-level bicycles or custom geometries where the material and construction method must speak the same language. This pre-configured XCr 4 Lugs 7 tubes set follows the standard Columbus selection for the XCr 4 Lugs series, with custom compositions available on request.

For a complete lugged stainless steel frame project, XCr 4 Lugs can be paired with compatible lug sets, traditional head tubes, steel fork blades and 1” fork steerers, all available separately through our catalog. On selected projects, the Columbus Minimal carbon fork, available with 1” or 1 1/8” steerer, offers a refined modern alternative while preserving the clean proportions of a classic frame.

We can also supply high-quality bottom bracket shells, braze-on bosses and CNC-machined dropouts, helping builders define a coherent set of components around the frame’s intended finish and geometry.

We normally try to keep pre-configured XCr 4 Lugs tubing kits available in stock for fast delivery. Special orders and custom tube selections may require additional lead times depending on Columbus production availability.

For builders looking to create a stainless steel frame with classic proportions, refined junctions and a truly made-to-measure character, Columbus XCr 4 Lugs offers one of the most exclusive starting points in contemporary framebuilding.
