Spitfire – Wheels FORMULA FOUR ”CLASSIC 99DU” – 54MM<\/p>\n
Spitfire Formula Four Classic 99a Wheels<\/strong> are the newest wheels from Spitfire. Tested by Spitfire Team riders, Formula Four Performance Urethane lasted longer, withstood more abuse, and performed better than all other wheels. Spitfire Formula Four Urethane was developed to combine all the desired properties of a performance wheel without sacrificing any one attribute at the expense of another. Formula Four\u2019s truly lasting performance urethane stems not from a single benefit, but from a combination of qualities and features that together produce a truly great wheel\u2014Formula Four Performance Urethane is unlike any other.<\/p>\n Specifications:<\/p>\n Formula Four Wheels retained more material, coned less, and maintained their original shapes and sizes longer than any other wheel. Formula Four Urethane is made using a 100% pure urethane compound. On hills, in the streets and parks, and during forced flat-spot testing in our lab, Formula Four wheels outperformed all others, resisting flat spots longer with less wear. Formula Four\u2019s exclusive combination of High Rebound and Hard Duro produces a faster wheel everywhere. Higher rebound for faster speeds on both rough and smooth surfaces. Hard Duro for a harder, faster ride that won\u2019t lose its shape over time. Formula Four\u2019s exclusive anti-stick slide provides a fast, consistent, and smooth slide from start to finish. Slide with confidence, knowing your wheels won\u2019t skip or catch mid-slide.<\/p>\n Formula Four gives you the highest level of control and consistent grip you can count on.<\/p>","protected":false},"excerpt":{"rendered":" The Spitfire Formula Four Classic is a wheel with good support in its design. 54mm and 99a make it a pretty good all-round wheel and you get a little more diameter for those who chase good speed.
