The new Hammer Special Effect is the perfect follow-up to the iconic Effect, Hammer’s most successful High-Performance ball in decades. Building on the proven power of the Huntsman core, featured in the original Effect, the Special Effect takes your game to the next level with HK22-Cohesion Solid, the hottest cover in bowling. This solid cover, crafted with factory compound, delivers exceptional mid-lane motion and an aggressive change of direction. Compared to the original Effect, the Special Effect still provides ease through the front of the lane but is slightly earlier, giving you the edge when there’s oil, and you need a bigger hooking shiny ball. Designed for versatility, the Special Effect is your go-to ball for consistent, high-performance results on a variety of oil patterns.
