VOLTRIC 80 YONEX Badminton (Racquet Unstrung) VT80 is more stable compared to conventional racquets due to the presence of NANOPREME in the shaft. TRI-VOLTAGE SYSTEM traditionally, extra weight at the top of the racquet frame has increased hitting power but reduced the speed of racquet handling. In contrast, a lighter top to the frame increases speed but causes a loss of hitting power.. The stiff racquet structure at the top of the frame allows the head to bend in a very controlled way and hold shuttles on the string bed for longer. The tin frame sides then allow the frame to flex more and transfer more energy to the shuttle. In VOLTRIC, the weight is balanced on the top of the frame and at the joint area which allows good handling while also maintaining power. Another innovative YONEX technology, SOUND FILTER uses new materials at the two and ten O'clock positions to reduce only high pitched and dull soundwaves. This produces a louder and sharper sound on impact to unsettle opponents.
