This profile minimizes friction on ledges, rails, and coping during technical flip tricks, grinds, and slides. The 54mm diameter hits the sweet spot for maintaining top rolling speed and clearing cracks without compromising pop or requiring riser pads on standard-height trucks. Finished with Spitfire's metallic silver Classic Swirl graphic across natural white urethane, it stands as an enduring staple for all-terrain street and park skating.\u003c\/div\u003e\n\u003cbr\u003e\n\u003ch3 data-path-to-node=\"2\"\u003eFeatures \u0026amp; Details\u003c\/h3\u003e\n\u003cul data-path-to-node=\"3\"\u003e\n\u003cli\u003e\n\u003cdiv\u003e\n\u003cb data-path-to-node=\"3,0,0\" data-index-in-node=\"0\"\u003eBrand:\u003c\/b\u003e Spitfire Wheels \/ Deluxe Distribution\u003c\/div\u003e\n\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cdiv\u003e\n\u003cb data-path-to-node=\"3,1,0\" data-index-in-node=\"0\"\u003eSeries:\u003c\/b\u003e Formula Four (F4) Classic Swirl\u003c\/div\u003e\n\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cdiv\u003e\n\u003cb data-path-to-node=\"3,2,0\" data-index-in-node=\"0\"\u003eWheel Diameter:\u003c\/b\u003e 54mm\u003c\/div\u003e\n\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cdiv\u003e\n\u003cb data-path-to-node=\"3,3,0\" data-index-in-node=\"0\"\u003eOverall Width:\u003c\/b\u003e 33.5mm\u003c\/div\u003e\n\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cdiv\u003e\n\u003cb data-path-to-node=\"3,4,0\" data-index-in-node=\"0\"\u003eRiding Surface:\u003c\/b\u003e 16.5mm\u003c\/div\u003e\n\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cdiv\u003e\n\u003cb data-path-to-node=\"3,5,0\" data-index-in-node=\"0\"\u003eDurometer:\u003c\/b\u003e 99a (optimal blend of controllable grip, speed, and smooth sliding)\u003c\/div\u003e\n\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cdiv\u003e\n\u003cb data-path-to-node=\"3,6,0\" data-index-in-node=\"0\"\u003eUrethane Formula:\u003c\/b\u003e 100% Formula Four Performance Urethane\u003c\/div\u003e\n\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cdiv\u003e\n\u003cb data-path-to-node=\"3,7,0\" data-index-in-node=\"0\"\u003eShape:\u003c\/b\u003e Classic (round cut profile engineered for quick response, reduced drag, and technical pop)\u003c\/div\u003e\n\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cdiv\u003e\n\u003cb data-path-to-node=\"3,8,0\" data-index-in-node=\"0\"\u003eColorway:\u003c\/b\u003e Natural White \/ Metallic Silver Swirl graphic\u003c\/div\u003e\n\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cdiv\u003e\n\u003cb data-path-to-node=\"3,9,0\" data-index-in-node=\"0\"\u003eCore:\u003c\/b\u003e Solid non-cored poured urethane\u003c\/div\u003e\n\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cdiv\u003e\n\u003cb data-path-to-node=\"3,10,0\" data-index-in-node=\"0\"\u003eBearing Seat:\u003c\/b\u003e Center-set \/ fully reversible\u003c\/div\u003e\n\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cdiv\u003e\n\u003cb data-path-to-node=\"3,11,0\" data-index-in-node=\"0\"\u003eWeight:\u003c\/b\u003e Approximately 0.54 lb (245 g) per set of 4 (~0.135 lb \/ 61 g per wheel)\u003c\/div\u003e\n\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cdiv\u003e\n\u003cb data-path-to-node=\"3,12,0\" data-index-in-node=\"0\"\u003eRecommended Disciplines:\u003c\/b\u003e Street, skateparks, ledges, rails, and transition\u003c\/div\u003e\n\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cdiv\u003e\n\u003cb data-path-to-node=\"3,13,0\" data-index-in-node=\"0\"\u003eCountry of Origin:\u003c\/b\u003e Made in the USA (San Francisco, CA)\u003c\/div\u003e\n\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cdiv\u003e\n\u003cb data-path-to-node=\"3,14,0\" data-index-in-node=\"0\"\u003eQuantity:\u003c\/b\u003e Sold as a set of 4 wheels\u003c\/div\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e","brand":"Spitfire","offers":[{"title":"Default Title","offer_id":67572885717142,"sku":null,"price":51.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0609\/6017\/8326\/files\/ss.jpg?v=1790972713","url":"https:\/\/cribtocrib.com\/products\/spitfire-wheels-formula-four-classic-swirl-white-w-silver-skateboard-wheels-54mm-99a-set-of-4","provider":"Crib to Crib Skateboarding Co.","version":"1.0","type":"link"}
