900 Global Portal Bowling Ball

A High-RG Asymmetric With the Sharpest Backend in the Global Line

About the Portal

The 900 Global Portal represents a different approach to a 900 Series ball. The all-new Conduit A.I. Core is purposely engineered as a high-RG, high-differential asymmetric, so it clears the front part of the lane better than any ball in the current Global line, ignoring the traffic in the heads and maintaining its energy for one of the sharpest backends the 900 Global brand has ever seen.

The stronger RB 92 Solid Reactive cover was strategically chosen to ensure optimal traction, and that all-new cover enhances the quick response time of the core. Factory-finished with Storm’s Power Edge and dressed in a clean, deep red, the Portal is the 900 Series ball for bowlers who want a heavy-oil asymmetric that saves its energy for the back of the lane.

Understanding the 900 Global Conduit A.I. Core and 900 Global RB 92 Solid Reactive

900 Global built the Portal to clear the front of the lane and unload on the backend. Specifically, the asymmetric Conduit A.I. Core pairs a high 2.59 RG with a strong .050 differential and a .019 intermediate differential at 15 lb, an unusual combination that pushes the ball through the heads while still flaring hard down lane, while the RB 92 Solid Reactive cover at a Power Edge finish supplies the traction to keep that quick core response under control on medium-heavy to heavy oil. The full per-weight numbers are listed below.

A Purpose-Built High-RG, High-Diff Asymmetric That Ignores the Front

At the heart of the Portal is the all-new asymmetric Conduit A.I. Core. Where most heavy oil asymmetrics run a low RG to rev early, the Conduit is purposely engineered the other way: at 15 lb it measures a high RG of 2.59 with a strong .050 differential and a .019 intermediate differential. The high RG lets the ball ignore the traffic in the heads and clear the front better than any ball in the current Global line.

The high differential and strong intermediate differential then take over down lane, producing heavy flare and one of the sharpest backends the 900 Global brand has ever seen. Because the core is asymmetric it has a defined preferred spin axis, so layout has a real say in how quickly the Portal responds; your pro shop can tune the pin and PSA to your game.

A Stronger Solid Cover Chosen to Keep the Quick Core Response in Check

Wrapping the Conduit A.I. Core is the stronger RB 92 Solid Reactive coverstock, strategically chosen to ensure optimal traction. A high-RG core that skids through the front needs a cover that can find the oil, and the RB 92 solid supplies that grip so the Portal reads the mid lane and sets up for its backend instead of skidding past the breakpoint.

The all-new cover also enhances the quick response time of the core, so the Portal changes direction decisively when it finds friction. Finished with Storm’s Power Edge for a clean, long-lasting box surface, it is built for medium-heavy to heavy oil; take the surface down at your pro shop for an earlier read on the freshest patterns.
