Yonexs newest VCore series gets a new update that brings their Namd graphite technology and Lock Booster System to the lineup.The Yonex V-Core Pro 97 310G incorporates new technology to create a racquet that gives more spin, speed and bounce with each hit. The VCore Pro series of racquets are designed to give players more devastating power and heavy drives. The high-density Black MicroCore material is infused in key areas of the frame to increase spin and stability. Isometric technology provides a 7% larger sweet spot, and a head light balance makes it nice and maneuverable. The Namd graphite technology gives the frame a unique flex with fast snapback so you can grip it and rip it. The Lock Booster System improves the grommet design which promotes string contact for efficient energy transfer and swing power. A weight of 11.4 ounces strung and narrow beams make this racquet perfect for players looking to add more pop to their game.
