The Motiv Subzero Forge Bowling Ball is a chilling new powerhouse in the Forge line, engineered for bowlers who demand maximum strength and control on high-volume oil patterns. With a deadly combination of the Detonator Symmetrical Core and the Leverage MXC Solid Reactive Coverstock infused with Duramax? technology, this ball is built to tear through oil with precision and authority. At its core is the Detonator Core, designed for a fast-spinning, low RG of 2.47 and a high differential of .055. This explosive combination creates massive track flare and torque, allowing the ball to read the midlane quickly and drive hard through the pins. Proven in previous Forge releases, the Detonator delivers the kind of relentless backend motion competitive bowlers rely on in tough oil conditions. Finished at 2000 Grit LSS, the Subzero Forge offers maximum traction without sacrificing control, making it an ideal weapon for fresh lane conditions, long oil patterns, and heavy volume.
