Introducing patented Flexbar technology by Channel Islands and Barron Flex. Flex, rebound, and resonance all play a role in how your board works. Harnessing and controlling these will take board performance to the next level. The Flexbar optimizes the energy and spring derived from both longitudinal and torsional tail flex in your surfboard by refining and focusing these forces under the back foot. Utilizing a combination of alternating foam densities and fiberglass through the entire board, Flexbar finally allows the surfer to feel and use the energy in your board through maneuvers. All surfboards will eventually lose their “pop” and begin to feel dead, Flexbar maintains the optimum flex pattern through the life of your board. All of this backed up by a one year warranty against breaking (read the warranty HERE), Flex-bar technology is the ultimate in performance.
