900 Global Cove Bowling Ball

Smooth, Stable Control for Medium-Heavy Oil

About the Cove

Ready to master medium-heavy lane conditions? The 900 Global Cove is the latest addition to the 800 Series, built for bowlers who want smooth, continuous motion they can repeat frame after frame. It pairs the all-new symmetric Magna A.I. Core with the RB 85 Hybrid Reactive coverstock to deliver the balanced, consistent read serious bowlers crave.

The Cove sits just above the Zen 25 in the lineup, finished at a clean 4000-grit surface in a Blue, White, and Teal cosmetic. The hybrid cover reads the mid-lane without overreacting, then arcs continuously to the pocket, so the ball tells you what the lane is doing instead of jumping. Pair it with its sibling, the pearl Ember, for a more dynamic look as the lanes transition.

Understanding the 900 Global Magna A.I. Core and 900 Global RB 85 Hybrid Reactive

900 Global built the Cove around stability and continuation. Specifically, the symmetric Magna A.I. Core uses an innovative dual-hemisphere design to create one of the most continuous, stable reactions in the entire 900 Global lineup, while the RB 85 Hybrid cover at a 4000-grit finish reads the mid-lane and clears the oil with a smooth, predictable shape. As a result, it holds a consistent line through transition and finishes with control, which makes it an outstanding benchmark for medium-heavy oil. The full per-weight specifications are listed below.

A Symmetric Dual-Hemisphere Core for Continuous, Stable Motion

At the heart of the Cove is the all-new symmetric Magna A.I. Core. At 15 lb it measures RG 2.49 and a .044 differential, numbers that produce strong but controllable flare with a smooth, readable shape. Its innovative dual-hemisphere design was engineered to deliver one of the most continuous and stable ball reactions in the entire 900 Global line.

That stability is the whole point. As a symmetric core, the Magna reads the lane predictably and repeats the same shape shot after shot, so whether you are facing fresh oil or a transitioning pattern, the Cove gives you reliable motion you can trust frame after frame. It is the kind of dependable read that makes a great benchmark piece.

A Hybrid Cover That Reads the Mid-Lane and Controls the Backend

The Cove wraps that core in the RB 85 Hybrid Reactive coverstock, finished at 4000 grit. A hybrid cover blends the early traction of a solid with the cleaner backend of a pearl, so the Cove reads the mid-lane for an honest look at the pattern, then makes a smooth, controllable move at the breakpoint rather than a sharp snap. The 4000-grit surface keeps that motion clean and continuous.

That balance of read and control is what makes the Cove so versatile on medium-heavy oil. It gets through the front of the lane while still grabbing the oil where it matters, then arcs to the pocket the same way every time. Leave it at the 4000-grit box finish for a smooth, controlled look, or take the surface down at your pro shop for an earlier read when the oil increases.
