900 Global Vengeance Bowling Ball

Relentless, Readable Strength for Heavy Oil

About the Vengeance

The oil did not get lighter. Your ball choice just got smarter. The 900 Global Vengeance was built for medium-heavy to heavy oil, delivering strength without overreaction. This all-new core and cover combination produces one of the most dynamic symmetric balls in 900 Global history: a readable, confident shape that holds up from the first frame to the last.

The Vengeance pairs the symmetric Blast A.I. Core with the RB 91 Solid Reactive coverstock at a 2000-grit finish, in a clean Grey cosmetic. It picks up in the mid-lane, stays smooth as the lanes transition, and still finishes with purpose down-lane. Strong enough to start league, stable and predictable enough to last: engineered for medium-heavy to heavy oil, and surprisingly good at everything else.

Understanding the 900 Global Blast A.I. Core and 900 Global RB 91 Solid Reactive

900 Global built the Vengeance to be strong and readable at once. Specifically, the symmetric Blast A.I. Core carries the highest differential in the 900 Global line, using a single-density shape to create a strong, predictable mid-lane read while saving energy for the back end. The RB 91 Solid cover at a 2000-grit finish grabs the oil for traction, then continues smoothly rather than jumping. As a result, it does not panic early and does not quit late, giving you a shape you can trust even when the lanes stop cooperating. The full per-weight specifications are listed below.

The Highest-Differential Symmetric Core in the 900 Global Line

At the heart of the Vengeance is the symmetric Blast A.I. Core, which carries the highest differential in the entire 900 Global lineup. At 15 lb it measures RG 2.47 and a strong .055 differential, numbers that produce heavy flare and a powerful, readable motion. The single-density shape creates a strong, predictable mid-lane read while storing energy for a confident finish.

That combination of strength and control is what makes the Vengeance so dependable. The high differential delivers the flare to clear heavy oil, while the symmetric, single-density design keeps the reaction smooth and repeatable. Translation: it does not panic early and it does not quit late, so you get shape you can trust from the first frame to the last.

A Strong Solid Cover That Reads the Mid-Lane and Keeps Driving

The Vengeance wraps that core in the RB 91 Solid Reactive coverstock, finished at 2000 grit. A solid reactive cover reads the lane earlier and more evenly than a pearl or a hybrid, and at a sanded 2000-grit surface it grabs the mid-lane strongly to handle medium-heavy to heavy volume, then continues through the pins instead of overreacting.

That strong, controlled read is what makes the Vengeance a true heavy-oil benchmark. It picks up in the mid-lane, stays smooth through transition, and still finishes with purpose. Leave it at the 2000-grit box surface for the strongest read, or polish it up at your pro shop for more length when the volume drops. For a cleaner, longer version of the same RB 91 cover, look at the polished Vengeance Returns.
