Brunswick Crown 78U Bowling Ball
The Brunswick Crown 78U bowling ball gives bowlers a harder urethane option approved for most USBC national competitions. As a result, this ball meets strict tournament regulations while offering more hook potential than typical urethane. Furthermore, Brunswick designed it specifically for tougher sport patterns and high rev rate players who need more from their urethane equipment.
Tiered Hexagon Core Design
The Crown 78U features the Tiered Hexagon core shape from Brunswick’s popular Crown Victory. Specifically, this core offers a higher RG and medium differential compared to other urethane balls on the market. Consequently, bowlers get more flare potential and stronger ball motion than standard urethane provides.
78 Durometer Urethane Coverstock
In addition to its dynamic core, the Crown 78U uses a harder 78 durometer urethane cover. This harder shell meets USBC requirements for national competition use. Moreover, the dynamic core offsets the limitations of harder urethane, creating ball motion options that other urethane balls simply cannot match.
