About this ball

Unbeatable! Hammer was the first to bring you the sought-after ball reaction created by a low RG and low differential asymmetric bowling ball. Obsession and Envy Tour started it all, and now Hammer is excited to offer the same unbeatable concept, upgraded with the Effect’s core body. Eliminating the Radial Disc from the bottom of the Huntsman core lowered the differential and intermediate differential, creating optimum numbers worthy of being Hammer’s next tour ball. We’ve returned to the Tour covers, using TourV3 Solid, helping the Effect Tour combat medium conditions and creating a predictable, smooth, and continuous ball motion.
