Yonex VCore Si 98 G tennis racket offers exceptional spin with greater bite. Features: Bt Hybrid Stringing System - new grommet technology and string hole design allows for more main and cross string movement resulting in longer dwell time and more spin. Isometric Head - The square head design creates a 7% larger sweetspot than conventional rounded head shapes.
Black Micro Core - carbon graphite and elastic particles have been added to high density foam which has been placed in key areas of the racket frame to produce a more solid racket face on impact. This allows a greater contact with the ball to help produce greater spin. Nanometric technology is the key component for the light weight of this racket. Nanometric uses Nanoalloy, a technology of Toray Industries. The bonding between carbon fibres in the shaft has been vastly enhanced to allow the shaft to be made 60% thinner, than a standard graphite shaft. The stiffness in the shaft is still maintained by the improved carbon bonds.
3D Vector Shaft - deep grooves in racket shaft improve racquet stiffness and reduce twisting of the frame, providing 20% more face stability than a conventional racquet. This delivers precise control at ball impact and greater bite for the most efficient transfer of power.
