Bowling Balls

The ZigZag Solid is a strong, continuous Asymmetrical ball with an RG of 2.501, a total DIFF of 0.045, and an Intermediate diff of 0.015. The core in the ZigZag was designed to allow a greater change in Differential numbers after drilling. The total Differential range after drilling can be as low as 0.030 and as high as 0.057, and the Intermediate Differential has a range of 0.010 to 0.030, making this a unique and versatile performance 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.
