For intermediate to advanced players looking to dominate with controllable power and comfort

Larger Sweet Spot

ISOMETRIC™ technology continues to help the world’s greatest players achieve global success. Developed over 30 years ago, the ISOMETRIC™ design increases the sweet spot by 7%*. Compared to a conventional round frame, a square-shaped ISOMETRIC™ racquet generates a larger sweet spot by optimizing the intersection of the main and cross strings. ISOMETRIC™ delivers greater control without sacrificing power. ISOMETRIC™ is a Trademark of Yonex CO., LTD. *Tested by Yonex

LINER TECH

Apply Extra Spin

By dramatically reducing the string entry angles in select grommets, the outer main strings are elongated to produce a wider sweet spot, providing greater snapback. With added string movement, players can grab the ball to apply extra spin.

Power with a More Flexible Frame

A strong, elastic graphite is added in the throat to improve frame stability and flex.

O.P.S.

Oval Pressed Shaft (OPS)Increased spin and control

Shaft corners are rounded for an ideal flex at impact to increase dwell time for optimal spin and directional control.

Vibration Dampening Mesh

For added touch and precision

A stretchy mesh material is wrapped around the graphite within the grip to filter unwanted vibrations.

Shockless Grommets

Shockless Grommets are integrated at the side and bottom of the frame to minimize muscle fatigue and provide a soft feel at impact to protect the wrist, forearm, and elbow by absorbing shock.
