The new evolutionary frame design of the Yonex Ai 98 tennis racquet delivers the fastest swing speed possible. Brand new Isometric technology provides a 7% larger sweet spot compared to conventional round frames. Ideal for attacking, hard-hitting players that produce powerful shots.
- Super Cushion Grip minimizes vibration.
- Shockless Grommets at the side and bottom of the frame minimize muscle fatigue.
- An improved Oval Pressed Shaft introduces rounder shaft corners, providing an ideal level of flex and stability.
New O.P.S.: Improved Yonex O.P.S. (Oval Pressed Shaft) manufacturing technology introduces rounder shaft corners providing an ideal level of flex, whilst a wider shaft face increases stability—resulting in extended ball dwell time for optimized ball spin and directional control.
Inner Isometric: Yonex evolved their Isometric Technology with an improved grommet system, applying both deep and shallow grooves inside of the frame. This new Isometric technology provides the EZONE Ai with a maximum sweet spot.
Trans-Weight System: Integrating the new Nanometric material, which improves the bonding strength between carbon fibers at the center and bottom of the frame, reduces the weight shift to the top of the frame. This Trans-Weight System results in a racquet head that reacts faster for quicker maneuverability and produces the fastest swing speed in Yonex history.
Shockless Grommet System: Yonex integrated Shockless Grommets at the side and bottom of the frame to minimize muscle fatigue during long matches. Provides a soft feel at impact plus the ability to protect the wrist, forearm and elbow by absorbing shock.
Dual Shut System: Dual Shut System improves comfort and control with every stroke. Shockless Grommets at the bottom of the frame reduces impact vibration and Quake Shut Gel, which is embedded inside the grip, removes even the most subtle discomfort from the frame. A 50% reduction in vibration compared to conventional models.
