Hammer Spawn Black Solid 15 Drilled w/Grips&Slug

Hammer Spawn Performance: High | Core: Gauntlet | Lane Condition: Medium to Heavy Oil Aggressive Transition Benchmark: The Hammer Spawn is designed as a high-performance asymmetrical benchmark that allows bowlers to remain aggressive even as lane conditions transition. It effectively bridges the gap between the Black Widow 3.0 Dynasty and the Zero Mercy Solid by delivering a unique combination of oil traction and powerful continuation. HK22C² Solid Coverstock: Utilizes the proven Zero Mercy cover technology to read the midlane with total confidence. Stable Core Dynamics: Paired with the Gauntlet core to create traction without the "early roll" often seen when moving inside. Enhanced Continuation: Specifically engineered to allow bowlers to open their angles while retaining energy through the pins. Siaair Finish: Arrives with a 500, 1000 Siaair Micro Pad finish for maximum bite on heavier volumes.
