JS-11 is the new Speed series racket integrating Ultra-thin Frame and Energy Bow Upgrade technology. The Ultra-thin Frame accelerates the swings and improves the anti-torsion performance. The Energy Bow Upgrade technology largely enhances the resilience of the racket, and helps deliver greater power with each swing. JS-11 is great for double players who specialize in speedy attacks.
The single-pass grommet hole construction creates less friction between strings, this effectively reduces tension loss, while extending string life.
Innovative technology combining the two popular frame structure SWORD and AERODYNAMIC, the AERO-SWORD can efficiently reduce air resistance and allowing a faster and greater hitback.
Inspired by military helicopter, multi-layered structure made by carbon fiber and composites, minimize material size, reinforce handling feel and performance at a critical standard.
Based the principle of mechanics, Energy Bow Upgrade is engineered with Ultra-thin Frame to enhance the anti-torsion performance and stability when hitting, while ensure effective power transmission to make the best use of hitting force and the resilience of the frame.
A design breakthrough—ULTRA-THIN FRAME is 7% thinner than the frame of traditional rackets, helping improve the player’s swing speed while maintaining the stiffness and anti-torsion performance of the frame.
