2G-Namd Flex Force
2G-Namd Flex Force is a highly elastic graphite material that allows the frame to flex and snap back quickly during impact. It is designed to support ball pocketing and spin potential while retaining a responsive feel.
The Yonex VCORE 100 in Scarlet carries the energetic look of the seventh-generation range and suits players who like to press from the baseline with heavy, shaped shots. Its nominal 300 g frame and 100-square-inch head occupy a versatile category: substantial enough for purposeful rallying yet more accommodating than a smaller competition head. It makes sense for developing and experienced recreational players with a reasonably complete swing.
Higher trajectory without abandoning direction
One of the design ideas behind the 2023 VCORE was to help the ball clear the net with margin before spin brings it down into the court. Yonex revised the upper hoop and used specialist grommets to encourage string movement. The 16/19 pattern gives players options between assertive topspin and a flatter ball when court position invites it.
2G-Namd Flex Force and VDM help define the frame response and feel at contact. Scarlet is the original colourway of this generation; Sand Beige arrived later as a visual alternative. Do not confuse it with Ruby Red 2026: the family resemblance is clear, but the generations and some engineering features are not identical.
Technologies
Aero Trench
A recessed upper-grommet channel is shaped to reduce aerodynamic drag. Within VCORE it is designed to help accelerate the racquet head and support spin, without guaranteeing a specific result for every player.
ISOMETRIC
Yonex ISOMETRIC uses a more squared-off head geometry that optimizes main and cross string intersections. Yonex reports an approximately 7% larger sweet spot than a comparable conventional round head, supporting a more forgiving response when contact is off centre.
LINER TECH
LINER TECH uses straighter string-entry holes so the main strings can move more freely on impact. The design supports ball pocketing and a more forgiving stringbed response, including on off-centre hits.
VDM
VDM (Vibration Dampening Mesh) is a flexible mesh wrapped around the graphite inside the grip. It filters unwanted impact vibrations to provide a smoother, more comfortable feel in the hand.
SILICONE OIL INFUSED GROMMETS
SILICONE OIL INFUSED GROMMETS uses silicone-oil-infused grommet material to reduce friction between the grommet and string. This helps the strings move and snap back more quickly after impact, supporting spin generation.
