Louisville BTZone100% aerospace grade graphite. With composites, performance and durability are dictated by the angle of the fibers and the wall thickness of the barrel. Louisville's high-strength fibers allow the best angle for performance while keeping the barrel wall thin for maximum flexibility.
BT Zone functions as the bonding of the barrel and handle as well providing a stiffer handle and transition.
Exclusive computer-designed pattern precisely positions the angles of graphite layers, resulting in an extra-long barrel with a huge sweet spot and outstanding performance.
Multiple layers of aerospace grade graphite fibers allow more layers for durability and a light, thin wall bar for performance.
