Racket Response Indicator：
A rival of high-end attack rackets, TK-770HT enables clear shots with high tension strings and reinforced stiffness supported by new-generation Fiber Reinforced System.
The box-shaped design effectively increases the stability and anti-torque, can stand higher string tension.
The NANO TEC technology works by evenly distributing nano-sized particles in the vacant space between carbon fiber bundles, this highly increases the overall stiffness of the carbon composite fibers, and reduces the distortion of the frame.
The single-pass grommet hole construction creates less friction between strings, this effectively reduces tension loss, while extending string life.
