Hammer Black Pearl Urethane: The Next Evolution in Urethane Dominance
Hammer has long been the undisputed king of urethane in bowling, a reputation solidified with the introduction of the legendary Purple Pearl Urethane. Now, as the sport moves into a new era with stricter regulations on urethane hardness, Hammer continues to lead the way with its latest innovation—the Black Pearl Urethane.
Built for the New Era of Urethane Bowling
Following the PBA’s recent rule change requiring urethane balls to have a hardness rating of 78D or higher, Hammer’s team of chemists and lab experts got to work. First, they introduced the game-changing NU Blue Hammer, and now, they’re raising the bar yet again with the all-new Black Pearl Urethane.
This ball is designed to deliver classic urethane control while meeting the new hardness requirements. It shares similarities with the Purple Pearl Urethane, but due to its harder cover, it’s a touch cleaner through the front and hooks slightly less overall. The result? A controlled, predictable motion that’s perfect for bowlers looking for straighter angles and precision shot-making.
Pro-Tested, Tournament-Approved
Hammer’s top pros have already put the Black Pearl Urethane to the test in competition—and the results speak for themselves. In comparison to the Purple Pearl Urethane, they’re seeing:
✔️ Four boards less with their feet
✔️ Two boards less with their eyes
✔️ Easier, straighter angles through the front part of the lane
Despite early skepticism about whether a harder urethane ball could match the performance of the Purple Pearl, the Black Pearl Urethane has exceeded expectations, proving to be a powerful weapon in competitive play.
Urethane Performance, Hammer Legacy
Hammer has always been at the forefront of urethane dominance, and the Black Pearl Urethane is proof that they continue to innovate and adapt while maintaining exceptional performance. Whether you’re a competitive bowler adjusting to the new regulations or someone looking for a reliable, harder urethane option, this ball is ready to deliver.
