Description
Spitfire Formula Four Conical Full 54mm wheels pair a 99D Formula Four urethane with a wide, stable conical profile. Spitfire lists the 54mm Conical Full at approximately 34mm wide with a 22mm riding surface. That puts it in a versatile middle ground: more speed and contact than a smaller technical street wheel without getting especially large. The cutaway sidewall helps with grind clearance, while Formula Four is designed for smooth, controllable slides and resistance to flatspots. Blue colorway; sold as four wheels.
