Spitfire Wheels Conical Formula Four 52mm 99a

Spitfire Wheels Formula Four Conical 52mm 99a is built for skaters who want a fast, controlled wheel with extra stability for technical street and park skating. The Conical shape gives you a wider riding surface than classic shapes, helping you lock into turns and landings with more confidence while still keeping the setup light and responsive. Made from Spitfire’s Formula Four urethane, these wheels deliver high abrasion resistance, unmatched flatspot resistance, smooth anti-stick slides, and a high rebound ride that stays consistent session after session.

• Smooth predictable slides with reliable release

• Extremely durable urethane for rough street spots

• Ideal for street, park, and small-to-medium transition skating
