At 54 mm tall with an ultra-narrow 16.5 mm riding surface, the Classic shape delivers uncompromising speed and razor-sharp agility for technical street lines. Rounded sidewalls slip cleanly over crusty curbs and rough copings without hanging up, letting your board rotate through flips with virtually zero drag. Poured in Spitfire’s rock-hard 101A durometer, these wheels maximize roll speed on smooth concrete and break into powerslides or reverts instantly and cleanly without sacrificing control when you need grip. Built with Formula Four urethane, they handle the most aggressive slides, stay dead round, and eliminate flatspots once and for all.
