Spitfire Reynolds Formula Four Classic 93 durometer - 54MM

The

Spitfire Formula Four Reynolds Classic 54mm

is a pro-model skateboard wheel featuring a specialized 93D (or 93A) durometer, designed to bridge the gap between soft cruiser wheels and hard park wheels. Developed over five years with input from pro skater Andrew Reynolds, these "Soft Sliders" are engineered to absorb vibrations on rough terrain while still allowing for controlled power slides and flip tricks.

Key Specifications

• Brand & Model: Spitfire Wheels Formula Four Andrew Reynolds Pro Model.
• Diameter: 54mm (a versatile size for both street and park skating).
• Hardness: 93D / 93A (the softest in the Formula Four collection, focused on impact absorption).
• Shape: Classic Shape (a medium-width profile with rounded sidewalls for all-around performance).
• Dimensions: 33mm to 33.6mm width with a 16mm to 16.5mm riding surface.

Performance Highlights

• Controllable Sliding: Unlike traditional soft wheels that are often too "grippy" to slide, these use a high-rebound compound that allows for consistent slides on crusty ground.
• Flatspot Resistance: Utilizes Spitfire’s Formula Four urethane, which is highly resistant to flatspots even with the softer durometer.
• Body Protection: The softer formula absorbs more impact and vibration, which can lead to less joint soreness during long sessions on rough surfaces.
• Terrain Versatility: Ideal for weathered street spots, "beat-up" pools, and rough asphalt where harder 99D or 101D wheels might feel too harsh.
