At 54 mm tall, the Classic shape maintains solid roll speed on longer lines, while the slim 16.5 mm contact patch keeps your board fast and responsive for technical flip tricks. Rounded sidewalls prevent hang-ups on crusty curbs or rough copings, letting you slip smoothly into every grind. Poured in the slightly softer 97A compound, these wheels soak up rough asphalt and cracked ground noticeably better without sacrificing rebound or clean slide control. Spitfire’s Formula Four urethane guarantees they stay perfectly round through heavy powerslides and keeps flatspots completely out of the equation.
