Spitfire Wheels Formula Four Conical Full 99A

Maximum Control. Wider Surface. Unstoppable Speed. For skaters who demand more grip and a wider footprint without sacrificing slideability, the Spitfire Formula Four (F4) Conical Full 99A is the ultimate choice. Engineered with Spitfire’s premium flatspot-resistant urethane, these wheels are built to handle high speeds, rougher ground, and heavy impact with ease. The Conical Full shape is defined by its wide riding surface and cut-in sidewalls. This design provides maximum control, lasting speed, and a wider profile that locks perfectly into the coping on transition or ledges in the streets. Combined with the legendary 99A Formula Four urethane, you get a wheel that grips when you need it to hold on, but offers a smooth, predictable slide when you throw a powerslide—all while completely resisting flatspots. Choose your size: 53mm: The perfect all-terrain size. Wide enough for solid control in the park, but still responsive enough for technical street skating. 54mm: Built for speed and stability. Ideal for bigger gaps, riding transition, bowls, or charging through rougher street spots. Technical Specifications: Formula: Spitfire Formula Four (F4) – Industry-leading speed retention and flatspot resistance. Shape: Conical Full – Wider contact patch, flat cut sidewalls for maximum lock-in and control. Durometer: 99A – The perfect balance of grip and smooth, anti-stick sliding.
