Urethane, evolved for today's tournament game. With the new USBC regulations for urethane balls, Brunswick built the Crown 78U to give bowlers a urethane option accepted in most USBC national competitions — with more flare potential and more dynamic numbers than typical urethane.

It features the Tiered Hexagon core from the Crown Victory: a higher RG, medium differential shape that provides an option not currently available on the market. The harder 78-durometer urethane cover has limitations that this more dynamic core helps alleviate, creating a new level of ball motion for urethane users.

Who It's For

• Tournament players — USBC-legal urethane with more shape than the rest.
• High-rev bowlers — added flare potential that softer urethane can't match.
• Short-pattern specialists — controllable urethane read on tougher tournament shots.
