SPITFIRE WHEEL F4 99D CONICAL 54MM YELLOW

The Spitfire Formula Four 99D Conical 54mm wheels in Yellow deliver a perfect balance of speed, grip and smooth slide control. Built with Spitfire’s world-leading Formula Four (F4) urethane, these wheels offer elite durability, flatspot resistance and consistent performance across all terrains.

The 99D durometer provides a slightly softer feel than 101A, giving skaters more grip and a smoother ride on rougher concrete without sacrificing pop or slide. The Conical shape features a wider riding surface and responsive profile — ideal for bowls, transition, all-terrain street skating and riders who want stability without losing agility.
