Yonex VCORE 100 (300g)


Technical data

It is always satisfying to verify that there are minimal deviations (in some cases even absent) between our measurements and the declared technical data, proving once again the great care and productive quality of the brand. Some differences with respect to the previous version need to be pointed out. First of all, the stiffness drops to 68 RA, with a dynamic rigidity of 139 Hz. Also, the polar index tells us that this new version of the frame is characterized by evenly distributed masses over the entire length of the racket.

The technologies employed in building this racket are truly remarkable.

The 2G-NAMD Flex Force consists in a particular graphite inserted in the shaft, allowing the racket to optimally bend and also resulting in a fast snap back.

The Vibration Dampening Mesh (VDM) is also used (already present on other Yonex rackets), whose main benefit is a greater impact feeling, due to its vibration dampening effect. It is also worth noticing that the 3% reduction of the beam width relative to the head, results in a greater maneuverability.

The section of the 10 central grommets has been modified with respect to the old version. These STRING SYNC GROMMETS leave more mobility to the strings, making it easier to produce spin. In addition, the LINER-TECH system is responsible for the horizontal growth of the sweet spot and enhanced snap back, offering as a consequence more rotation also on off-centered shots.

Finally, we already know the AERODYNAMIC TECHNOLOGY, which makes the frame highly maneuverable.
