Brunswick Crown 78U

Brunswick proudly introduces the Crown 78U, a next-generation urethane ball designed to meet the evolving needs of competitive bowlers. Built to comply with hardness standards for most USBC national competitions, the Crown 78U goes beyond regulation—delivering enhanced performance for tougher tournament patterns and for bowlers with higher rev rates who rely on urethane control. To elevate motion without sacrificing predictability, Brunswick engineered the Crown 78U with the Tiered Hexagon core from the Crown Victory. This higher RG, medium differential design produces increased flare potential and more dynamic numbers than traditional urethane offerings, giving bowlers an option not currently available on the market. The harder 78-durometer urethane cover naturally limits ball motion, but the added engine power from the core helps overcome those constraints, creating a new level of control-focused movement with improved downlane continuation. For even greater impact, the Crown 78U features DynamiCore, Brunswick’s industry-leading outer core material. This durable technology reduces compression at impact, boosting hitting power and producing a stronger sound and improved pin carry—an undeniable performance advantage for bowlers who rely on urethane. The Crown 78U offers the smooth, predictable shape bowlers expect from urethane, now paired with added versatility and strength. For bowlers seeking a competitive urethane option built for today’s conditions, the Crown 78U delivers a new benchmark in performance.
