Thermal Core Technology (TCT)
A new process that heats the racquet core to higher temperature during the curing phase, so that the racquet structure is cured uniformly inside and out. This TCT modification to the carbon fibres makes the frame extremely responsive - stiff yet playing with the reactive properties of a more flexible frame. The resulting hit is the best of both worlds - the control of a very stiff frame with the power of a more flexible frame.
