Technology / Features

1. 2G-Namd Flex Force
   Advanced graphite material that enhances shaft flex and snapback, storing energy during flex and releasing it explosively on impact.

2. Namd
   Yonex’s graphite bonding process that increases adhesion between fibers and resin, improving energy transfer.

3. Extra Slim Shaft
   Reduces air resistance and increases swing speed while maintaining strength.

4. Rotational Generator System
   Balances weight across the grip end, frame top, and joint to allow smooth transitions and quicker recovery after powerful swings.

5. Power-Assist Bumper
   Tungsten-infused bumper at the frame top that directs more weight into the shot, especially for smashes.

1. New Built-in T-Joint
   Strengthens the joint area, improving stability and reducing frame twist.

2. Solid Feel Core
   Absorbs vibrations on impact for a cleaner, more solid feel.

3. Isometric Frame
   Enlarges the sweet spot by optimizing the frame shape, offering more forgiveness on off-center hits.

4. AeroBox Frame
   Combines aerodynamic design for faster swings with structural strength for solid hits.

5. Energy Boost Cap Plus
   Specially shaped cap that allows the shaft to flex while stabilizing the racket face to prevent twisting.
