A NEW GENERATION OF URETHANE FOR TODAY’S GAME: The Brunswick Crown 78U delivers a modern urethane motion built for today’s USBC standards—designed to meet new hardness regulations while giving competitive bowlers the reliable control and precision they depend on.

78D SHELL FOR TRUE TOUR-LEVEL CONTROL: Engineered with a harder 78 hardness urethane shell, the cover on the Crown 78U provides the predictability bowlers expect from urethane, with added stability on tougher patterns and high-friction environments where control is everything.

HIGH-INTELLIGENCE CORE ENGINEERING FOR MORE FLARE: Powered by the Tiered Hexagon core from the Crown Victory, the Crown 78U pairs higher RG with medium differential to create more flare potential and enhanced motion—overcoming the limitations of harder urethane for a shape not found in traditional options
