Formula Four isn't a marketing label; it's a genuinely different urethane compound, engineered for more speed, better slide, and longer flat spots than a standard wheel.\u003c\/p\u003e\n\u003cp\u003eAt 56mm and 99 duro, this is a hard, fast-rolling wheel built for smooth ground — skateparks, smooth street spots, anywhere you want to carry speed without the wheel doing the work for you. The Classic shape's rounder profile keeps it locked into slides and grinds predictably, which is exactly why it's remained unchanged for decades.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eKEY FEATURES\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eClassic shape — Spitfire's original, most-imitated wheel shape\u003c\/li\u003e\n\u003cli\u003eFormula Four urethane — faster, longer-lasting, more resistant to flat-spotting than standard urethane\u003c\/li\u003e\n\u003cli\u003e99 duro — hard and fast for smooth terrain\u003c\/li\u003e\n\u003cli\u003e56mm diameter — taller roll for momentum through transitions and open ground\u003c\/li\u003e\n\u003cli\u003eSold as set of 4\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eSPECS\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eDiameter: 56mm\u003c\/li\u003e\n\u003cli\u003eHardness: 99D (99A duro)\u003c\/li\u003e\n\u003cli\u003eShape: Classic (OG)\u003c\/li\u003e\n\u003cli\u003eFormula: Formula Four urethane\u003c\/li\u003e\n\u003cli\u003eSold as: Set of 4\u003c\/li\u003e\n\u003cli\u003eRecommended Terrain: Street, park, smooth surfaces\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eABOUT SPITFIRE\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eSpitfire Wheels has been a cornerstone of skateboarding since 1987, built around the philosophy of \"Keeping the Underground Lit.\" Formula Four, launched in the late '90s, remains one of the most significant urethane advances in skateboarding — a genuine performance jump over standard wheels, not just a premium price tag.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWHY BUY FROM TWELVE BOARD STORE\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e✔️ Free shipping Australia-wide on orders over $90\u003c\/li\u003e\n\u003cli\u003e✔️ Expert skate advice from real riders, 7 days a week\u003c\/li\u003e\n\u003cli\u003e✔️ Easy returns for a hassle-free experience\u003c\/li\u003e\n\u003cli\u003e✔️ Huge range of skate, snow \u0026amp; electric gear\u003c\/li\u003e\n\u003cli\u003e✔️ Proudly Australian owned \u0026amp; operated\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Spitfire","offers":[{"title":"Default Title","offer_id":44768451395627,"sku":"83534","price":567.0,"currency_code":"HKD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/2638\/2396\/files\/spitfire-f4-og-classic-wheels-99d-56mm-01.jpg?v=1786684870","url":"https:\/\/twelveboardstore.com.au\/en-hk\/products\/spitfire-f4-og-classic-wheels-99d56mm","provider":"Twelve Board Store","version":"1.0","type":"link"}
