Conical Full Shape – With a wide riding surface and a cutaway design, this shape has unmatched control and lasting speed everywhere.
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.
