Spitfire Formula Four 97d 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.

   Radial Shape–        Round edges, slim to medium riding surface offers a quick, responsive , round edge shape.

   Wide–        More traction and stability at high speed so you’ll be less likely to slip out of your line.

   Smooth Surface–        Smooth wheels have less surface friction than treaded wheels and are easier to slide.

   97a Durometer–        Offers more grip than harder wheels and more slide than softer wheels. Great for beginners wanting more control on smooth surfaces or for filmers looking for a smooth roll.
