The heart of the kiteboard is its core, so we paid great attention to choose the right materials for the production of Jay kiteboards. We have decided to choose the lightest and overall the best available wood for cores in the snowboarding industry. The wood is one continuous piece from tip to tip without any joints, because every joint causes a breaking point, this allows the wood to maintain its natural flex properties, which are essential for excellent flex and pop of Jay boards. Our goal was to have a core with properties and advantages of wood and to keep it very light. Speed model is produced with 1D Carbon technology, we use ABS side walls construction. ABS is a high strength, very durable thermo-plastic material. CNC shaped, hand fine finished rails bond together the upper and lower layers of carbon. Together they create a torsion box which improves the stiffness of the board in torsion.
