Hammer is excited to introduce a revolutionary ball – actually a game-changer for bowlers seeking alternatives to traditional urethane ball reaction. With recent changes to PBA rules regarding traditional urethane, Hammer took on the challenge of producing a ball that would mimic the performance attributes of the famous Purple Pearl Urethane Hammer without using urethane… and we nailed it. The NU Blue Hammer is “not urethane” but delivers a urethane ball motion. It is versatile, smooth, consistent, and predictable, making it ideal for challenging lane conditions. Bowlers will experience all the advantages of a reactive ball that can be used in any competition while benefiting from the classic Purple Pearl Urethane ball motion that has dominated the lanes for years.

Not Urethane
LED (w/ reactive coverstock) Core

The core is the exact same as the urethane model; however, the numbers are different due to the density of the reactive shell versus the urethane; this raises the differential and creates more flare, producing a stronger and more angular backend motion.
