IST Composite Technology joins the barrel and handle together, providing players with a great solid feel and larger sweet spot. IST features a solid connection between the handle and barrel, giving players maximum performance, even on inside hits. Vibration from a miss hit is absorbed before it reaches a player's hands, allowing you to maintain acceleration through impact for increased and more consistent performance. Swing1 Inner Disc Technology (S1 iD) 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 performance limit, giving players maximum allowable performance. Thinner high-strength and light-weight graphite fibers allow for reduced wall thickness, creating better performance while maintaining durability. Thinner graphite fibers allow use of more layers in the barrel for added strength, but with an overall wall that is thinner. Balanced swing weight. Louisville Slugger end cap. Synthetic grip, 7/8" standard handle.
