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 100L in Scarlet suits players who want to build a topspin game but feel more confident handling less overall mass than the standard VCORE 100. At a nominal 280 g with a 100-square-inch head, it offers an inviting balance for developing players, juniors progressing to full-length frames and recreational tennis players who prefer easier preparation.
A lighter frame with its own rhythm
The 16/19 pattern supports varied spin and trajectory, while the 330 mm balance retains a noticeable sense of head presence. This is not merely a regular VCORE 100 minus a few grams: it has a different swing feel, and the player still needs to generate pace through technique. Its strengths are especially relevant in quick exchanges, returns and transitions towards the net.
Seventh-generation VCORE combines ISOMETRIC geometry, aerodynamic shaping and solutions intended to encourage string movement. 2G-Namd Flex Force and VDM add to that generation’s frame response. Scarlet identifies the 2023 edition, not the updated Ruby Red construction from 2026. Choose it for the balance between swing freedom and purposeful spin, not simply because it has the lowest number on the scale.
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.
