The new 2014 Louisville Slugger SBZ214-AB Z-2000 Slow Pitch softball bat employs S1iD Technology that allows the barrel to flex to its maximum allowable performance level from SWING 1. Two inner discs are positioned inside the barrel at the sweet spot to stop the barrel from flexing past the legal limit. For players, this means they really do get maximum performance allowable and a larger performing sweet spot. Louisville Slugger uses their high quality LS-2X composite on the Z-2000. This new thinner high-strength and lightweight graphite fiber blend allows for reduced wall thickness, creating better performance while maintaining durability. The thinner fibers have allowed Louisville Slugger to use more layers in the barrel for added strength, but with an overall wall thickness that is thinner. The iST barrel to handle connection gives players maximum performance, even on inside hits. With a balanced swing weight, the Z-2000 is built for performance. For added comfort, the Z-2000 features 7/8" standard handle with a synthetic grip. Louisville Slugger: Be the Best. Or Swing the Rest. The Z-2000 is approved for play in ASA, USSSA, NSA, ISA and ISF.
