The Yonex EZONE Ai 98 is an update to the EZONE XI 98 of the EZONE series and will be used by Ana Ivanovic in 2014. The evolutionary new frame minimizes wind resistance to produce an ultra-fast swing. Features "Isometric" technology with an improved shockless grommet system, expanding the sweet spot and reducing the frame vibration. The Isometric head shape maximizes the head size allowing ultimate swing speed and consistent power for off centered hits. New "Nanometric" material designed to improve the bonding strength between carbon fibers at the center and bottom of the frame, reducing the weight shift from the bottom to the top of the frame. This trans-weight system results in a racquet head that reacts faster for quicker maneuverability. The Dual Shut System technology improves comfort and control featuring shockless grommets at the bottom of the frame reducing impact vibration. Quake Shut Gel embedded inside the grip, removes any discomfort from the frame.
The EZONE Ai 98 is optimal for the intermediate to advanced player with a faster swing looking for an excellent control oriented stick. Extra forgiveness from the 98 square inch head without diminishing the feel thanks to a thin 23/24/19mm tapered beam. Great comfort and control with every shot thanks to the new Dual Shut System. Maintains the feel of a larger sweetspot than its 98 square inch headsize would suggest, feeling solid yet forgiving. Heaviest offering in the EZONE Ai series.
