Tri Strut TR3 Composite Barrel - Somewhere you may recall learning how crystal structures are perfectly created in triangle formations, making them the strongest and most stable compounds. No? Well it's true. The triangle formation at the molecular level of the composite provides a fixed ratio of sides and angles, so it's strong, stable and predictable - without any unnecessary weight. Engineered durable and light enough to be worthy for Doublewall duty. Tri Strut TR3 Composite Handle - The molecular structure of the composite handle is designed to efficiently transition power from your hands to the barrel giving you balance and consistency in every swing. Geo Endcap - The dual density internal cap is full of load balancing triangles. It's designed to maintain the stiffness of the barrel while dampening impact vibration to give you amazing feel, shot after shot. 1.15 BPF USSSA Stamped - Approved for play in 2012 and beyond New 2012 Model! -10 Length to Weight Ratio 2X Doublewall Design 2 5/8 Inch Barrel Diameter TR3 Strut Composite Half + Half One Year Warranty
