YONEX Vcore 100S Tennis Racket

As used by Caroline Wozniacki. This racket has been constructed with an Isometric square head shape, formed by reducing the dead space found in a conventional round frame whilst keeping the sweet spot the same size. As a result, the racket is easier to swing through and has superior manoeuvrability.

Where the longest main and longest cross strings meet in the string-bed is known as the sweet spot. In conventional rackets, the sweet spot is the area where 8 main strings and 11 cross strings meet. However, with the Yonex Isometric square head shape, 10 main strings meet 13 cross strings to produce a larger sweet spot. This equates to a 10% larger sweet spot than conventional round head shape rackets.

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 Oval Pressed Shaft balances stability and flex for a longer dwell time and more spin, as well as providing the ideal amount of flex at the throat for a longer dwell time to deliver more spin and pinpoint accuracy.

The cushioned underside layer of the Yonex Super Cushion Grip reduces vibration, further enhancing the soft feel at impact provided by Shockless Grommets. This exceptional cushioning performance also helps protect the wrist, arm and elbow against shock-related injuries.

The deeper grooves in the 3D vector shaft improve racquet stiffness and reduce twisting of the frame for 20% more face stability than a conventional racket.

The new generation of X-Fullerene has four radial ribs which unite the carbon atoms into a unique soccer ball structure. The X-Fullerene features in the resin which bonds carbon fibres to create a cross-link construction. This construction translates to a 5% increase in repulsion power and 15% greater stability.
