The Yonex VCORE Alpha SL in Ruby Red is the lightest full-length member of the Alpha family. Its nominal 245 g weight is particularly relevant to juniors moving from a shorter racquet to adult length, as well as newer players who want to concentrate on technique. The 100-square-inch head gives useful contact area without asking the player to manage the mass of a demanding tournament frame.

Easier preparation while the swing develops

For someone building consistent strokes, moving comfortably between forehand, backhand and volley can matter more than carrying extra grams. Alpha SL is designed with that freedom in mind. A 340 mm balance retains head presence, and the 16/18 pattern leaves scope to develop topspin gradually. The fit is strongest when the player is still learning to accelerate through the ball with repeatable timing.

ISOMETRIC, NANOMESH NEO, Servo Filter and VDM form part of the design, but they do not turn a very light frame into a heavy competition racquet. Its real advantage is manageable overall mass, leaving more attention for preparation, clean contact and completing the stroke.

Technologies

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.

Nanomesh Neo

NANOMESH NEO is a material used in the composite construction of selected Yonex racquets. It is designed to combine frame strength with flexibility, supporting a responsive feel at impact.

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.
