The Spitfire Formula Four OG Classic 99a Wheels represent the perfect intersection of heritage design and modern urethane technology. Combining Spitfire’s original “cut-away” shape from the early days with the industry-leading Formula Four (F4) urethane, these wheels are built for skaters who want a wider riding surface without the extra weight.
The OG Classic shape features a unique wide profile with vertically cut sidewalls, providing a larger contact patch than the standard Classic shape for increased stability and grip on transitions. Crafted from 99a durometer Formula Four urethane, these wheels offer a high-rebound ride that is fast on all surfaces and virtually immune to flatspots. The 99a hardness provides a balanced feel—offering enough grip for slick marble or park floors while maintaining a smooth, controllable “anti-stick” slide when you need to break into a power slide or revert.
