Spitfire Lock-ins Formula Four 101 A
Spitfire Formula Four Lock-Ins 101A skateboard wheels combine premium Formula Four urethane with Spitfire’s distinctive asymmetric Lock-Ins shape.
The straight inner edge creates a defined contact surface for curbs and rails, while the outer side features a shaped conical profile. This design gives each wheel two different profiles.
The 101A durometer delivers a hard, direct response for skaters who prefer a precise and consistent feel. Spitfire Formula Four urethane provides high resistance to abrasion and flatspots while maintaining its performance over time.
The Anti-Stick Slide System promotes smooth, controlled slides. Available in multiple sizes, the diameter, width and contact patch vary by selected size, while the Lock-Ins shape, 101A durometer and Formula Four construction remain consistent across the range.
Choose Spitfire Lock-Ins 101A wheels for precise response, lasting performance and controlled slides.
