Spitfire Formula Four 99d Rowan Zorilla Spitball Radial Full Skateboard Wheels- 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.
