Created by YONEX in 1980, the ISOMETRIC head shape is a unique and evolutionary breakthrough technology in racquet design. In conventional racquets, the sweet spot is located where main strings and cross strings meet. The YONEX ISOMETRIC head shape allows us to increase the number of main and cross strings that meet in the centre of the racquet to produce a sweet spot which gives a 7% more effective hitting area for you to make match winning shots.
Quad Force Gear
Expanded Sweet Spot and More Power
Thick side grommets have been equipped on the four corners of head, extending the effective length of the strings. Additionally, the racquet frame on the whole has been made thicker to varying degrees, resulting in the frame achieving uniform stiffness.
With an overall expanded sweet spot, players are able to experience an increase in repulsion off of the string bed.
Newly Designed Shaft
Improved Face Stability Grants Better Control
The shaft has been made with a cross-sectional design, resulting in a 15% increase in shaft stiffness, also cutting down on twisting at the throat.
The Tri-Shut System utilizes three different materials equipped in the racquet that work together to absorb shock and cut down on unpleasant vibrations.
ERGO POWER GRIP
Easy Transfer of Power into Your Racquet
The ERGO POWER GRIP cuts down on openings between your hand and the grip, putting more power into your shots. Designed as a near-regular octagon, the grip end is thick, becoming thinner towards the top, resulting in a sloped design that provides improved handling.
