Spitfire Wheels Formula Four Classics 101 A

Maximum Speed. Unbeatable Slide. Zero Flatspots. Take the most proven, popular wheel shape in skateboarding history and pour it with the fastest, hardest urethane on the market. The Spitfire Formula Four (F4) Classics 101A are engineered for skaters who want top-end speed, lightning-fast response, and slides that go for days. While the 99A version offers a bit more grip, the 101A durometer is noticeably harder. This means less friction and more speed on smooth concrete, making powerslides, bluntslides, and quick reverts feel completely effortless. Combined with the legendary Classic shape—featuring a traditional rounded profile and medium riding surface—you get a highly versatile wheel that won't stick on ledges and refuses to flatspot, no matter how hard you skate it. Choose your size: 52mm: The gold standard for technical street skating. Lightweight, quick on the pop, and perfect for precise flip tricks and ledge combos. 53mm: The ideal all-terrain balance. Offers a slightly higher top speed and better clearance for a mix of street spots and skatepark transition. Technical Specifications: Formula: Spitfire Formula Four (F4) – Unmatched speed retention and absolute flatspot resistance. Shape: Classic – The #1 proven rounded profile for all-around performance and technical response. Durometer: 101A – Harder, faster, and slicker for effortless slides and smooth-surface speed.
