900 Global Cove Bowling Ball

Ready to conquer medium-heavy oil patterns with confidence? The 900 Global Cove Hybrid Bowling Ball is built to provide a perfectly balanced motion that’s both smooth and continuous. It’s the latest evolution in the powerful 800 Series, engineered for bowlers who demand predictable backend movement and excellent lane read. When paired with the Ember, the Cove fills the gap to give you complete coverage for all medium lane conditions.

At the heart of the Cove lies the innovative Magna A.I. Core — a symmetric design with a unique dual-hemisphere shape that promotes stability and control. Its consistent, smooth motion helps maintain rhythm through transitions, making it a go-to ball when reliability is key. Whether you’re chasing strikes or trying to grind out tough frames, the Cove offers the confidence and precision you need.

Wrapped in the newly developed RB 85 Hybrid Reactive Coverstock, this ball features a fast oil absorption rate for better traction and a true mid-lane read. The number “85” signifies its performance ranking — placing it among the most advanced, consistent coverstocks in the 900 Global arsenal. For bowlers who crave versatility and dependable hook potential, the Cove delivers a benchmark motion that reads early but never quits downlane.
