The remarkable Powerarm design converts the acquet into an ultimate power machine. It ensures that the ball is accelerated from the strings withgreat force at every stroke. The decoupled design of the Powerarm means that the tennis racket is extremely powerful. The yoke of the new POWERARM has also been developed further along Powerbridge lines. The new trapezoid crosssection of the yoke is even more torsion-resistant, thus providing more control for every stroke.
