SPITFIRE ROWAN SPITBALL 57mm FORMULA FOUR RADIAL FULL 99a WHEELS

Formula Four Urethane – Formula Four urethane is unlike any other. Both in the streets and under high-speed stress tests in Spitfire's lab, Formula Four wheels retained more material, coned less and kept their original shapes and sizes longer than any other wheel. Lock Ins Cut – Asymmetrically cut, you can get the benefits of conical outer walls while the inside wall is cut straight, giving you a flat surface to lock in your grinds Smooth Surface – Smooth wheels come with a shiny coating on the riding surface that feels grippy at first, but wears away quickly. Medium Profile – Your classic wheel shape, versatile all-around wheel for street/park skating.
