Description
Unleash the Warrior!
The Spartan charges into the Ebonite lineup as a fighter, built for heavy oil. This one demands volume — and rewards you with incredible continuation and backend motion rarely seen in a ball with this much traction. The Spartan’s 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. The combination of aggressive core numbers and this game-changing cover creates an
oil-fighting warrior that looks unstoppable from start to finish.
HyperKinetic22
The Next Breakthrough
Our Research and Development team has worked hard to develop the next breakthrough in cover technology. After pouring and throwing hundreds of bowling balls with dozens of new base reactive urethane formulations combined with a wide variety of chemical components and additives, our ball team has created something exceptional – the new HyperKinetic22 coverstock base material.
The Science Behind It
HK22, as we’ll often refer to it, features enhanced color and clarity by engineered nano micellular phase separation technology, dramatically improving the cover’s translucency. And through Quasi prepolymer staged reactions, intermolecular friction is reduced to manifest a dynamic interactive polymer morphology with the lane.
Leading the way
DynamiCore is Brunswick’s industry leading innovation in outer core technology. This leap in bowling ball technology is a more durable outer material that yields less compression upon impact increasing hitting power and creating an undeniable difference in sound and pin carry.
