The Defined Split-Five SpokeA modernized take on the split-five spoke design utilizing our Advanced Rim Technology that not only rigidifies, but also reduces the weight of the wheel drastically without sacrificing performance.
Our newest Advanced Rim Technology (A.R.T.) is the latest manufacturing process that incorporates traditional monoblock wheel casting methods with spin forming technology to drastically improve the material properties and enhances the overall strength of our wheels.
The A.R.T. process impacts the micro-structure of aluminum by utilizing three hydraulic rollers to apply pressure to form the inner rim area after the wheel has been casted. The rollers move down the barrel, applying pressures to stretch, compress, and form the entire wheel barrel, ultimately increasing the tensile strength and elongation properties.
The end product is a lighter, stronger wheel that has an increased load capacity and shock resistance over the traditional cast aluminum wheel. A.R.T. provides up to a 25 percent weight reduction compared to a traditional cast wheel. The M615 weights for 20 inch sizes start at 23 lbs per wheel.
