The VCORE series is made to give aggressive players a great boost power through unique racquet design. The new VCORE Tour F features “fins” carved into the inside of the racquet head to increase serve speed by 6% while cutting down on air resistance by 14%. The VCORE Si features the BT HYBRID STRINGING SYSTEM, which gives players an increase in spin due to specially shaped grommet holes that allow for greater string movement.
