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 Ruby Red brings the spin-oriented personality of the range to players who would rather not manage the full mass of the 300 g VCORE 100. With a 280 g nominal weight and a 100-square-inch head, it encourages earlier preparation, quick exchanges and comfortable movement at the net. It is relevant to progressing juniors using adult-length frames and recreational players building a more purposeful topspin game.
An easier swing with a recognisable VCORE identity
The 16/19 pattern provides room to shape the ball, while its 330 mm balance retains some head presence during the swing. That matters because 100L is not merely a lighter duplicate of the regular 100. The difference is most useful when reacting under pressure or maintaining technique through longer rallies.
ISOMETRIC geometry and the updated grommet system follow Yonex’s eighth-generation aim of making contact and string movement more forgiving. The frame also incorporates 2G-Namd Flex Force, Servo Filter and VDM. Choose this configuration when swing freedom matters to you more than the added mass of a stronger player’s racquet.
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.
