Cup-Stack Carbon Nanotube
The YONEX compound Cup-Stack Carbon Nanotube construction with four times more elasticity than carbon nanotube, in combination with a high-strength nanotube coating, minimizes notching of the string at intersecting points. This construction delivers high durability and high repulsion power.
Vectran
The Vectran high strength and high-elasticity spiral winding prolongs derability and racquet stringing tension.
