XCr tubing is the only stainless and seamless tube family available in the cycling industry. XCr is made from a solid billet bar of stainless steel, and it is drawn out into a tube continuously until it reaches its final wall thickness, leading to incredible tensile strength. Also, XCr is rustproof - meaning no paint is necessary.
Suggested filler material for TIG welding: APX4S
