SPITFIRE FORMULA FOUR APRIL SHANE O'NEILL CLASSIC 54MM 99D (Set of 4)

The Spitfire x April Shane O'Neill wheels pair the signature style of one of the most technically flawless street skaters alive — the Australian pro who founded April Skateboards — with Spitfire's industry-leading Formula Four urethane. F4 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 holds its speed and shape session after session. Hand-poured and engineered in San Francisco, CA.

At 54mm, these run the Classic shape — the most proven shape in skateboarding, with round sidewalls and a slimmer riding surface designed for control in every situation. That slimmer profile means quick acceleration, reduced weight, and responsive, precise control, which is exactly why it's a favorite for technical street skating — dialed for flip tricks, ledges, and tech lines. The 54mm diameter and versatile 99a durometer round it out: fast and slidey like a harder wheel, but forgiving enough for everyday pavement. Finished in a clean natural colorway. Sold as a set of four.
