Hammer Black Widow Mania Bowling Ball, Elevate your game with sharper length and backend punch.

The Hammer Black Widow Mania brings a thrilling upgrade to the iconic Widow line. Designed to pick up where the Black Widow 3.0 leaves off, the Mania introduces unmatched length and angularity for bowlers who crave aggressive backend motion.

At the heart of the Mania is the trusted Hammer Gas Mask Core, paired with the game-changing HK22 – Cohesion Pearl Reactive coverstock—the same formula found in last year’s fan-favorite, the Hammer Effect. This combination gives the ball clean motion through the front of the lane and an explosive, angular reaction off the breakpoint.

With a 1500 grit polished finish, the Mania is perfect for medium to heavy oil lane conditions, making it a versatile, high-performance option for league players and tournament bowlers alike. Finished in a sleek black and blue colorway, the Mania doesn’t just dominate—it does it in style.
