Ebonite Spartan Bowling Ball

Ebonite Spartan Bowling Ball

The Ebonite Spartan bowling ball tackles heavy oil conditions with ease. As a result, this ball delivers strong continuation and powerful backend motion. Furthermore, it offers these traits while still providing excellent traction—a rare combination in today’s market.

Iron Fist-Inspired Core Design

The Spartan’s core draws from the proven Iron Fist design found in Ebonite’s popular Warrior series. Specifically, this aggressive core shape stores energy for heavy oil play. Consequently, bowlers get a strong, angular motion through the pins even on the toughest patterns.

HK22C² Coverstock with Optimize Solid Additives

In addition to its powerful core, the Spartan features Ebonite’s most advanced cover technology. The HK22C² coverstock includes Optimize Solid additives that maximize oil absorption. As a result, this ball cuts through oil and maintains its reaction from the first frame to the last.

Who Should Throw the Spartan?

This ball fits bowlers who regularly face heavy oil conditions. Moreover, it works well for players who need a reliable benchmark ball for sport patterns or flooded house shots. Therefore, if you struggle to get balls to respond on slick lanes, the Spartan belongs in your bag.
