At 58mm and 99A, this is the big, fast option in the F4 lineup: maximum riding surface, hard duro for smooth surfaces, and a shape that locks into grinds while holding speed between them.\u003c\/p\u003e\n\u003ch3\u003eKey Technical Features\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cb\u003e58mm diameter:\u003c\/b\u003e A larger size that holds speed and rolls smooth over cracks and rough pavement — ideal for transition, cruising and skaters who want more momentum.\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003e99A durometer:\u003c\/b\u003e A harder duro built for speed and slide control on smooth concrete, plazas and skateparks — less grip than softer options, more speed.\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eFormula Four urethane:\u003c\/b\u003e Spitfire's signature compound engineered for speed, consistent grip and flatspot resistance — stays round longer than standard urethane.\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eConical Full shape:\u003c\/b\u003e A fuller, wider profile than the standard Conical — more riding surface for extra stability, longer wear life, and confident lock-ins on grinds.\u003c\/li\u003e\n\u003cli\u003e\u003cb\u003eSet of 4 wheels.\u003c\/b\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eWhy You'll Love It\u003c\/h3\u003e\n\u003cp\u003eThe Conical Full 58mm 99A is built for skaters who want to go fast and stay in control — the wider profile gives you more wheel underfoot on transition and rough ground, while the 99A hardness keeps things slippery and quick on smooth surfaces. It's the Spitfire for skaters who skate big — transition, ditches, plazas — and want a wheel that matches their ambition. Formula Four means it holds its shape long after cheaper wheels have flatspotted out.
