What’s new within the VCORE Pro? Yonex has thickened up the frame design, widening the outer beam of the racquet which creates added frame stability and repulsion. Yonex adds in an all-new FlexCon System for the racquet flex and feel. The tapered and elongated box-frame shaft is now composed of Flex Force + Flex Fuse graphite for precise control. The Flex Fuse technology gives a softer feeling thanks to the integration of a shock-absorbing polymer integrated within the graphite’s resin, resulting in increased flex and a soft more plush feel. The Flex Force graphite is perfect for increased ball-pocketing, allowing the racquet to quickly snap back for greater spin and faster ball acceleration off the string bed.
