TENSEI 1K Black is built specifically to suit powerful swings with no sacrifice in feel and responsiveness. TENSEI 1K Black utilizes a focused application of 1K carbon fiber -- the same high-performance material found in the TENSEI 1K Pro family -- to increase strength in the handle, drive down torque and provide the signature "1K feel." TENSEI 1K Black also utilizes our Xlink Tech Resin System in the tip section to bolster the shaft's tip strength and increase the shaft's durability. Tip stiffness and torque are further controlled through the use of 40-ton carbon fiber in the shaft's construction. Add the subtle, yet premim matte clear finish and you get a shaft that gives high speed players the low launch, low spin performance with the great feel they need and the good looks they desire.Key Features Include:- Low launch, low spin- Firmest tip section in 1K family- Focused application of super-premium 1K carbon fiber for stability in handle- Xlink Tech Resin System drives carbon fiber volume way up for better feel without sacrificing strength or durability- 40-ton material for strength
