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 Ruby Red suits players who want to dictate from the baseline and use spin as a tactical tool rather than a last-minute adjustment. A 100-square-inch head offers more margin for contact than a smaller 98-inch option, while the 300 g nominal frame weight gives the racquet useful substance during assertive rallies. In the eighth-generation range, this is the versatile choice for people who value both a lively response and the freedom to shape the ball.
Room to create the trajectory you need
The 16/19 string pattern supports varied shot shapes, from higher, dipping topspin to a firmer drive through the court. Yonex redesigned the upper frame and grommet system to encourage string movement and snapback. ISOMETRIC geometry makes the effective hitting area more accommodating when timing is challenged by pace or awkward court positions.
2G-Namd Flex Force, Servo Filter and VDM contribute to the frame design and impact feel. Their presence does not replace good technique, but it helps explain the balance Yonex is targeting. VCORE 100 is an appealing match for developing and experienced players who want to take initiative without committing to a heavier, more specialised frame.
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.
Servo Filter
SERVO FILTER is an elastic film integrated between graphite layers in the frame. It is designed to reduce unwanted vibrations while preserving useful feedback to the hand for a more precise impact feel.
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.
