Brunswick’s new Crown 78U Solid Urethane is designed to meet the latest USBC urethane regulations while giving bowlers a powerful, modern urethane option that thrives in competitive environments. Built for tougher sport patterns and high-rev players who rely on control without sacrificing motion, the Crown 78U pairs a harder 78D urethane shell with the dynamic Tiered Hexagon core borrowed from the Crown Victory. This higher RG, medium differential core adds flare potential and enhanced motion not commonly found in today’s urethane offerings. By combining a compliant cover with an engine that offsets the limitations of harder urethane, Brunswick delivers a fresh and effective motion shape—one that fills a gap in the market and gives urethane bowlers a new level of performance.
