Hammer 3-D Offset Attack
PBA Approval Date
Release Date
Discontinued

The 3D Offset, released earlier this season, has been an excellent hit for Hammer; it brought back one of the most significant releases in bowling history and has been successful on the lanes. One of the most exciting things about the 3D Offset Attack is that it is Hammer’s first release with the new HyperKinetic 22 cover base. In this release of HK22, you’ll notice more rich and impressive colors and a cleaner and more responsive cover, which creates more area at the breakpoint, leading to higher scores.
