Hammer NU 2.0 Mid Performance Bowling Ball No flash. No frills. Just pure performance. The NU 2.0 is the latest evolution in Hammer’s Not Urethane line, designed for bowlers who love the control and shape of urethane but need more strength and versatility. Poured in a clean, matte grey that reflects its workhorse mentality, the NU 2.0 features NU Active, a new coverstock that’s slightly more aggressive than the original NU Blue. This formula provides slightly more hook where bowlers need it most, without sacrificing the smooth, predictable motion that made the NU line a favorite. For players battling high-friction league conditions or looking for a more forgiving alternative to traditional urethane at tournaments, the NU 2.0 delivers a motion you can trust and results you can count on.
