Building off the success of the Exogrid, H2 Technology is the next step in optimizing the composite/alloy hybrid design. The exclusive H2 design bonds the ST+20 barrel and the 3X composite seamlessly, providing the outstanding performance of a 1-piece stiff handle design. The H2 design utilizes a full 3X composite handle and transition area. The move to a full 100% graphite composite design in the transition allows for an even stiffer handle than offered in Exogrid. Graphite is lighter and stronger than aluminum, allowing for a stiffer handle. The barrel section of H2 is constructed with the industry leading ST+20. Its outstanding strength and toughness provide the performance, feel and sound that top players demand. A lighter handle/transition means a longer barrel and sweet spot. A stiff handle produces more barrel flex, resulting in maximum trampoline effect and, ultimately, greater performance.
