Spitfire Conical Formula Four 99 A

Spitfire Conical Formula Four 99 A skateboard wheels combine Formula Four urethane with one of the brand’s most distinctive shapes.

The symmetrical Conical profile features shaped sidewalls and a contact surface designed to balance control and smooth rolling without adding excessive wheel weight. Its sidewall geometry retains the same essential characteristics across the available sizes.

The 99A hardness delivers a precise, controlled response. Spitfire’s Formula Four compound provides high resistance to abrasion and flatspots while maintaining consistent performance throughout use.

Available in multiple sizes, these wheels retain the same Conical shape and urethane formula, with dimensions varying according to the selected diameter. Choose the right size for your setup and complete your skateboard with a set of four Spitfire wheels.
