The Yonex VCore Pro 97 is for the experienced and advanced players looking for a flexible racket with precision and feel. ISOMETRICTM technology continues to help the world’s greatest players achieve global success. Developed over 30 years ago, the ISOMETRICTM design increases the sweet spot by 7%*. Compared to a conventional round frame, a square-shaped ISOMETRICTM racquet generates a larger sweet spot by optimizing the intersection of the main and cross strings. ISOMETRICTM delivers greater control without sacrificing power. ISOMETRICTM is a Trademark of Yonex CO., LTD. First used in our snowboards to reduce vibrations at impact, Vibration Dampening Mesh (VDM) is now used in four of our racquet series. VDM is a stretchy mesh material that is wrapped around the graphite within the grip to filter unwanted vibrations and improve touch and precision. A tapered and elongated box-frame shaft is composed of Flex Force and Flex Fuse graphite for precise control of the ball. A shock-absorbing polymer is integrated within the graphite’s resin for increased racket flex and a softer, more plush feeling.
