Hammer introduces a true innovation in ball reaction—the NU Blue Hammer, a groundbreaking release designed to deliver the trusted motion of urethane without actually being urethane.

With recent PBA rule changes impacting traditional urethane, Hammer took on the challenge of recreating the legendary performance of the Purple Pearl Urethane Hammer—and succeeded. The result is “NU” (Not Urethane) technology, offering the same smooth, controlled motion bowlers rely on, while remaining compliant and competition-ready.

The NU Blue Hammer provides exceptional control, consistency, and predictability, making it ideal for challenging lane conditions where managing reaction is critical. Bowlers get the benefit of a reactive-style ball that maintains the signature urethane-like shape—smooth through the front, controlled in the midlane, and continuous through the pins.

This unique combination makes it a powerful option for players looking to control the lane without sacrificing hitting power or versatility.
