If you had to pick a wheel to put on anyone's skateboard, you'd do very well with a set of Spitfire Formula Four 99d Classics Skateboard Wheels. Unbeatable durability in a time-tested all-round shape, chances are your favorite pro is riding these.
Classic Shape – The #1 shape in skateboarding worldwide - proven for speed and control.
99a Durometer – More speed and control on all surfaces. Unmatched flatspot resistance. Smooth, anti-stick ride. High-rebound compound.
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.
