An oil-fighting warrior. The Spartan charges into the Ebonite lineup built for heavy oil. It demands volume — and rewards you with incredible continuation and backend motion rarely seen in a ball with this much traction.

Its core shape is inspired by the proven Iron Fist design from the Warrior series, now paired with the most advanced cover in the game: HK22C² with Optimize Solid additives. Aggressive core numbers plus that game-changing cover make the Spartan look unstoppable from start to finish.

Who It's For

• Heavy-oil players — demands volume and rewards it with big continuation.
