Description:
1. Aerodynamic structure frame, reduce the air resistance within speed increasing and explosive force while smashing.
2. Build in twice, made with Japanese high modulus graphite:
 (1) Intensify rigidity of the frame
       A. High string tension durable
       B. Enhance the performance effectively
       C. Reinforce the control and the performance of the frame
(2) Enhance the anti-torque of the frame and shaft:
      A. Reinforce the performance of control of the racket
      B. Well-contact generates
3. 100% screening strictly: no filling, no coating, no defect
4. Pyramid structure build-in frame enhance the rigidity
5. 1.5K carbon woven prepreg increase the strength of the racket
6. 1.5K graphite woven shaft increase the anti-torque and flexibility of the racket
7. Single-line holes + Double-eyelets improve the durability of string and keep the string tension stable
8. Nano technology patent NO: XL03149232.0.
