Spitfire Wheels Formula Four 99DU Classics
Spitfire Wheels Formula Four 99DU Classics represent a pinnacle in skateboard wheel technology, engineered for optimal performance across a wide range of skateboarding disciplines. The proprietary "99DU" Durometer rating signifies a balanced hardness that provides both excellent grip for precise control and responsiveness, while maintaining sufficient durability to withstand the rigors of street and park skating. This specific formulation of urethane is designed to deliver a smooth, consistent ride, reducing vibration and enhancing the overall feel of the board.
The Formula Four Classics feature a classic conical shape with a rounded riding surface, a design choice that maximizes contact patch for superior stability and predictable slide characteristics. This shape promotes confidence during grinds and slides, allowing skaters to push their limits with a reliable and forgiving wheel. The uniform density and high-quality construction ensure that these wheels maintain their shape and performance over extended use, resisting flat spots and chunking more effectively than many conventional wheels.
Beyond their material composition and shape, Spitfire Wheels Formula Four 99DU Classics are meticulously manufactured to meet the exacting standards of professional skaters. Each wheel undergoes rigorous quality control to guarantee consistent diameter, bearing seat precision, and overall integrity. This dedication to craftsmanship results in a wheel that not only performs exceptionally but also offers a visually appealing and durable product, making it a trusted choice for skaters seeking the best in performance and longevity.
