Spitfire's Formula Four is the most trusted wheel in street skating — and the Conical shape in 101D is the choice of skaters who want maximum speed, buttery slides, and wheels that hold their shape session after session.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\"\u003eMade with Spitfire's Formula Four compound for unmatched abrasion resistance — fewer flat spots, more controllable grip, lasting speed no matter the terrain, and a smooth anti-slick slide with a longer lasting size and shape. The Conical shape features a smooth riding surface in a medium profile maximizing traction for precise carving, with a hand-cut conical design for quick response and less weight than wider profiles. At 101D, these are among the hardest wheels on the market — built for skatepark and street skating on smooth surfaces where you want maximum pop response and effortless slides. 53mm keeps the setup low and fast, ideal for technical tricks. Sold as a set of 4.\u003cspan class=\"inline-flex\"\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\"\u003e\u003cstrong\u003eSpecs:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul class=\"[li_\u0026amp;]:mb-0 [li_\u0026amp;]:mt-1 [li_\u0026amp;]:gap-1 [\u0026amp;:not(:last-child)_ul]:pb-1 [\u0026amp;:not(:last-child)_ol]:pb-1 list-disc flex flex-col gap-1 pl-8 mb-3\"\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eDiameter: 53mm\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eWidth: 33.5mm\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eDurometer: 101D\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eShape: Conical\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eProfile: Medium\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eSurface: Smooth\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eUrethane: Formula Four\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eSold as a set of 4\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\"\u003ePick up a set at \u003cstrong\u003eStamford Skate Shop\u003c\/strong\u003e — Stamford, CT's local skate shop for Spitfire Formula Four wheels, pro decks, trucks, and everything you need to build your perfect setup.
