Crupi BMX race frames are built with seamless drawn 6061 T6 tubing. Very few other frame companies use this type of material because it is more expensive. What does this mean to you? The cold reduction process of the tubing improves dimensional tolerances and simply makes a stronger frame. The material is so good that each material run comes with quality certification sheets that show that the material was tested for mechanical properties and an aluminum chemical analysis. All Crupi frames feature this seamless drawn material which is ovalized at the ends to provide more welding surface.FEATURES:*6061 Seamless Drawn tubing*Ovalized tubing shape*ovalized chainstays for added stability*Parallel dropouts ensure perfect geometrySPECS:Micro – Expert XL: 22.2mm post, 1″ clampAll Pro Sizes: 26.8mm post, 1 1/4″ clamp
