The Hammer Effect Tour bowling ball—a groundbreaking evolution in ball reaction. Hammer pioneered the low RG and low differential asymmetric ball with the iconic Obsession Tour and Envy Tour, and now, the Hammer Effect Tour continues this legacy. This ball features the updated Effect core, designed with an optimized low differential and intermediate differential by removing the Radial Disc from the Huntsman core. This adjustment creates the ideal numbers for the ultimate tour-level performance. Outfitted with the trusted TourV3 Solid cover, the Hammer Effect Tour is engineered to excel on medium oil conditions, delivering a smooth, continuous, and reliable motion.
