Description
The Spitfire Formula Four Classic 93a Wheels represent a technical breakthrough in urethane performance, often referred to as the “Soft Sliders.” Developed over five years with extensive testing from Andrew Reynolds, these wheels are designed to solve the age-old problem of choosing between a soft, forgiving ride and the ability to slide predictably.
By utilizing a high-rebound 93a durometer Formula Four urethane, these wheels absorb the vibrations and impact of crusty street spots and rough asphalt, making them much easier on your joints during long sessions. Despite the softer feel, they maintain the legendary F4 flatspot resistance and feature a specialized anti-stick compound that allows them to slide consistently on ledges and rough ground—maneuvers typically reserved for much harder wheels. The Classic shape provides a medium-width riding surface with round sidewalls, proven for world-class speed and control.
