At 53 mm tall with a slim 16 mm contact patch, the Classic shape gives you instant board feel and lets your setup flick through technical tricks without extra drag. The rounded edges let you slide effortlessly into grinds on crusty curbs and tight copings without hanging up on the pinch. Poured in Spitfire’s rock-hard 101A durometer, this formula generates blistering roll speed on smooth concrete while snapping cleanly into reverts and powerslides on command. Spitfire’s Formula Four urethane holds up against the most abrasive surfaces, stays perfectly round, and keeps flatspots off your wheels for good.
