Oversized with its widest point at the center, the Kona booms offer amazing comfort, performance and durability within a T8 aluminum body and tail extension! The monocoque (one piece) profile provides extraordinary stiffness and strength. The double pin lock system generates optimal load distribution and a stiff connection between the boom body and tail end, even when extended to the maximum. The robust front incorporates an anti-friction lever and an integrated mast shim.
