The box-shaped design effectively increases stabilty and anti-torque allowing the racket to withstand higher string tensions.

The single-pass grommet hole construction creates less friction between strings effectively reducing tension loss while extending string durability.



Core shell rubber is added into the carbon fibre and foam rubber is used to fill the frame which not only increases the extension strength of carbon fibre, but also improves the resilience. The Foamex becomes much more compact during the foaming process and provides better shock absorption once the foaming is complete.
