Yonex Vcore 100 LG 2018 RED The highest-spin producing racquet in company history, the new VCORE embraces the latest in Yonex technology, such as a drag-reducing Aero Trench and Liner Tech, meaning the strings enter the racquet at a straighter angle, toallow for easy access to incredible spin. Used by Caroline Gracia, winner of two WTA finals, the Roland Garros womens doubles winner and US Open womens doubles finalist. Technology: Isometric - the head shape is a unique and evolutionary breakthrough technology in racquet design. The Yonex Isometric racquet design increases the number of main and cross strings that meet in the racquet, increasing the size of the sweet spot and producing more match winning shots. Aero Trench - to achieve faster head speeds for increased spin potential, the new Aero Trench reduces drag by uniquely hiding the grommets located at the top of the racquet frame. Liner Tech - 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. Specifications: Head Size: 100 sq. in. Weight: LG: 280g / 10.6oz Size: LG1-3 Length: 27 in. Material: H.M.
