Five bold yet elegant spokes rise from a recessed hub at the centre of the RD215 and stretch out to the perimeter of the wheel where they merge seamlessly with the rim. This elegant matte black alloy wheel is manufactured as a single piece. The manufacturing process ensures maximum stiffness and weight reduction with a rigorous testing process to ensure the highest quality. Tests include FEA Analysis, Helium Air Leak Testing, and X-Ray Scanning. And the wheel has been JWL and VIA approved.
