Spitfire Skate Like a Girl Formula Four 99d - Og Classic  Skateboard Wheel - 54mm

The Spitfire Formula Four (F4) 99d "Skate Like A Girl" OG Classic 54mm wheels are a high-performance collaboration celebrating the 25th anniversary of the Skate Like A Girl non-profit organization. These wheels use Spitfire’s premium Formula Four urethane, designed for speed and unmatched flat-spot resistance.

• Size: 54mm (a versatile mid-size suitable for both street and park/bowl skating).
• Durometer: 99d (offers more grip than 101d while maintaining a smooth, anti-stick slide on most surfaces).
• Shape: OG Classic—this is Spitfire's original cut-away shape, featuring a wider riding surface and lightened cut-away sidewalls for better control.
• Dimensions: Approximately 32.3mm width with a 22.2mm riding surface.

• Control & Speed: The wider riding surface provides more stability at high speeds and better grip on slick surfaces compared to narrower shapes.
• Smooth Ride: The 99d hardness is specifically praised for minimizing vibrations on rougher asphalt while still performing well on smooth skatepark concrete.
• Flatspot Resistance: Built with Spitfire's Formula Four 100% true performance urethane, these wheels are highly resistant to developing flat spots during power slides.
