SPITFIRE FORMULA FOUR MULTIBALL OG CLASSIC 54MM 99D (Set of 4)

The Spitfire Formula Four Multiball wheels bring Spitfire's classic team styling to their industry-leading F4 urethane. Formula Four is the pro standard: more speed and control on every surface, unmatched flat-spot resistance, a smooth anti-stick slide, and a high-rebound compound that — in both street use and Spitfire's high-speed lab tests — keeps its shape and size longer than any other wheel. In short, it lasts, which makes a premium set like this a real value over time.

At 54mm, these run the OG Classic shape — Spitfire's original cut-away profile. It features a wider riding surface for extra grip and stability, lightened with cut-away sidewalls to keep the weight down, blending an old-school look with modern performance. The 99a durometer hits the versatile sweet spot: fast and slidey like a harder wheel, but forgiving enough for everyday terrain. Finished in a natural colorway with the Multiball graphic. Sold as a set of four.
