High stability - a greater moment of inertia on the face amplifies power and control.
Yonex's IPS (Integrated Power Weight System) positions extra weight at 3 and 9 o'clock on the frame, giving the face of the frame a greater moment of inertia. The IPS construction translates into minimum torque within the frame for maximum stability, energy transfer and control.
The IPS technology benefits the player by positioning extra weight at the sides of the racquet frame to give the face awhich in turn results in more power while maintaining stability.
