Spitfire Formula Four 99d Atlantic Drift Natural Conical Full Skateboard 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.

99a Durometer: More speed and control on all surfaces. Unmatched flatspot resistance. Smooth, anti-stick ride. High-rebound compound.

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

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

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