Brunswick Crown 78U Bowling Ball

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.

Performance Ratings

• Category: Advanced – Performance features with a wide range of reactions for all skill levels
• Control: Predictable, smooth ball motion throughout the lane
• Reaction Shape Strength: 40 out of 100 – Moderate reaction strength

Who Should Throw the Crown 78U?

This ball fits tournament bowlers who need a USBC-approved urethane option with more backend reaction. Additionally, high rev players who overpower traditional urethane will appreciate the stronger core dynamics. Therefore, if you want urethane control with added punch, the Crown 78U fills that gap.

Don’t forget to grab some Max Tack to keep your new ball looking like new! And, after the deep clean, the BowlersMart shammy is perfect for wiping off the oil and debris. Help prolong your bowling balls life so it can keep striking!
