The Hammer Zero Mercy Solid bowling ball is Hammer’s latest high-performance release, designed specifically for bowlers facing heavy oil lane conditions who want maximum traction and aggressive motion. Released in November 2025, this visually bold ball features a striking four-color design combined with groundbreaking technology that delivers power, control, and a fierce hook potential.
Core Technology
At the heart of the Zero Mercy Solid is Hammer's new Super Offset core. This core is a modern reimagining of Hammer’s legendary Offset design, now enhanced for more torque, energy release, and downlane motion. With a relatively high RG and very strong differential and intermediate differential, the ball creates a powerful arcing motion while maintaining versatility for different bowler styles.
HK22C² Coverstock
The ball is wrapped in the advanced HK22C² coverstock, which blends Hammer’s well-regarded HK22 formula with Cohesion technology and a Chrome additive. This combination results in one of the strongest, most aggressive solids Hammer has produced, offering explosive traction in oil and robust lane control. The finish amplifies hook potential, making it ideal for use when lane conditions are challenging and control is paramount.
Performance
Bowlers report that the Zero Mercy Solid digs in early on the lane and delivers a hard-arching, continuous motion through the pins. It stands out especially on heavy oil, providing the power and lane-read bowlers need to maintain scoring potential even when other balls may struggle to grip. The ball’s versatility allows it to be effective for both high-rev and lower-rev players, and its aggressive nature helps avoid leaving corner pins by driving through the pin deck with authority.
