At its core is Thin Con construction, which utilizes tapered tips/tails for reduced swing weight and enhanced tip flex. Included also is Biaxial Glass for 90/0 degree angles, as well as a Fushion 1500 Base that is harder, faster, and more durable. Signature to the Kink is its Foundation Tuned Core, which is a tip to tail wood core with added durability for a greater retention of camber and flex — which ultimately leads to more strength, pop, and a more crisp response.
