15lb Effect Pearl (DISCO)

Hammer Effect

Unlike any other. The Hammer Effect shatters expectations as the first bowling ball ever poured in four colors, delivering a visual statement as bold as its performance.

But the eye-catching design is just the beginning. The Hammer Effect delivers a clean look through the front of the lane with an aggressive mid-lane read and explosive backend motion, setting a new standard in the High Performance category. This release introduces the all-new Huntsman core, engineered with physical traits reminiscent of iconic Hammer favorites like the Vibe and Black Widow, creating a powerful blend of control, continuation, and hitting power.

Wrapped around the Huntsman core is an advanced evolution of HK22 technology, featuring HK22 – Cohesion Pearl. This upgraded formulation dramatically increases responsiveness and backend traction, allowing the ball to unleash a sharper, more decisive move when it encounters friction.

Once you see the Hammer Effect in action, one thing becomes clear—this level of performance changes everything.
