Product Description Introducing the Hammer 3-D Offset Assault the latest addition to the acclaimed 3-D line! The goal when developing this new Hammer ball was to provide strength, aggressive ball motion, and versatility. The Hammer 3-D Offset Assault bowling ball does all that, making it a go-to ball for Hammer fans across a wide range of conditions, especially on the fresh or when there is medium to heavy oil. The core and cover combination work perfectly to make this a true winner. We used a hybrid version of HK22-Cohesion to create the ideal ball reaction for meeting our goals with this ball. The High Rev Offset core has a celebrated past because of how it delivers on the lanes; the versatile numbers and medium-range asymmetry help provide the aggressive yet versatile motion Hammerheads love. Our testers loved the Hammer 3-D Offset Assault from all angles. It will be the first ball out of the bag, and you may never need to switch balls because this continues from everywhere.Color: Red/Cherry/Dark Red *Please note that colors may slightly vary from image shownCoverstock: HK22C – Cohesion HybridWeight Block: High Rev Offset Asymmetric CoreFactory Finish: 500 / 1000 / 2000 Siaair Micro PadFlare Potential: 5-6″ Plus (High)Radius of Gyration (RG): 2.489Differential (Diff): 0.053Intermediate Differential (Mass Bias): 0.008WeightRGDiff.Interm.
