Hammer Maximum Effect Upper Mid Performance Bowling Ball You asked for more, now get ready for Maximum. The Maximum Effect is the biggest, boldest ball yet in the wildly popular Effect line, built specifically to give you the Effect ball motion you love, but on heavier conditions. For the first time, we’ve combined our HK22 – Cohesion cover with CFI (Carbon Fiber Infused) technology, creating unmatched traction and power on medium to heavier conditions. Finished at a gritty 500/1500 and designed with a stunning four-color swirl, the Maximum Effect isn’t just the strongest Effect yet; it’s a statement. Hammerheads wanted more teeth, more traction, more Effect, and we delivered. This is Maximum performance, Maximum confidence—Maximum Effect.
