Introducing the Brunswick Crown 78U — giving bowlers a new urethane option approved for use in most USBC national competitions. In addition to these regulations, Brunswick recognizes the use of harder urethane balls on tougher tournament patterns and for high rev rates. They developed a new urethane ball with more flare potential and more dynamic numbers to meet the needs of those bowlers. The new Crown 78U features the Tiered Hexagon core shape from the Crown Victory, a higher RG and medium differential core, providing bowlers with an option not currently available on the market. The harder 78 durometer urethane cover has limitations that a more dynamic core helps alleviate, creating a new level of ball motion option for bowlers using urethane.

Ball Tech

Advanced - Performance features with a wide range of reactions for bowlers of all skill levels.

Control - Predictable, typically a smooth ball motion throughout the lane. Balls with higher numbers will have more overall reaction.

Reaction Shape Strength: 40 - The higher the number the stronger the reaction shape – with 1 being the least and 100 the most.

Dynamicore Technology - This ball features Brunswick’s innovative outer core technology called DynamiCore. This industry-leading technology is a more durable outer material that yields less compression upon impact increasing hitting power and creating an undeniable difference in sound and pin carry.
