Description
The Spitfire Formula Four (F4) Conical 99A Wheels are a top-tier choice for skaters who want a balance of performance and control. This version features the Conical shape, which is characterized by hand-cut, tapered sides and a slightly wider riding surface than the standard Classic shape. This design offers a quicker response and less weight while still providing a secure, “locked-in” feel on rails and ledges.
Built with Spitfire’s elite Formula Four urethane, these wheels are famous for their industry-leading flatspot resistance. The 99A durometer is the most versatile hardness available, providing the perfect amount of grip for slick skatepark surfaces while maintaining a smooth, predictable slide on rougher street spots.
