Designed to handle serious volume, the Spartan delivers a powerful midlane read with exceptional continuation and a strong, driving backend that’s rarely found in balls this aggressive. Its core design draws inspiration from the proven Iron Fist shape from the Warrior series, now elevated with Ebonite’s most advanced cover technology to date: HK22C² with Optimize Solid additives. Together, the aggressive core numbers and cutting-edge cover create a relentless oil-fighting force that maintains energy through the pins and finishes every shot with authority.
