New technology and structure, combined with innovation, increase string elasticity and movement, giving players access to the greatest spin in Yonex tennis history. ISOMETRIC - Developed over 30 years ago, the ISOMETRIC™ design increases the pure hitting area by 7%. Compared to a conventional round frame, the ISOMETRIC™ racket creates a larger sweet spot by optimizing the intersection of the vertical and horizontal strings. ISOMETRIC™ technology provides greater control without sacrificing power.AERO FIN TECHNOLOGY - The aerodynamic fins found on the SV model have been improved and positioned on the lower part of the VCORE frame. The new Aero Fins feature strategically cut sections that allow for improved maneuverability.AREO TRENCH - To achieve higher head speed for increased spin potential, the new Aero Trench reduces air resistance by hiding the grommets located on the top of the racket frame.2G-NAMD™ FLEX FORCE - Aggressive, attacking spin for precise control is achieved thanks to a carbon nanotube structure that binds graphite fibers, reducing energy loss. Due to its elastic properties, the material flexes and provides a quick bounce.SILICONE OIL INFUSED GROMMET - New silicone oil infused into the grommet allows the racket to quickly flex and return to its original shape.ENLARGED FRAME TOP - A wider frame at the 2 and 10 o'clock positions increases the contact area with the ball, providing a larger clean bounce area.NEW THROAT DESIGN - Torsion resistance helps stabilize the racket, reducing power loss.
