New energy boost cap with new frame design and racquet length.
The square-shaped ISOMETRIC frame shape is designed to keep vertical strings at a similar length, as well as the horizontal strings to produce an expanded sweet spot in all directions.
New Grommet Pattern
The single-pass grommet hole construction provides more grommet holes for a more high-performance stringing pattern.
Solid Feel Core
The built-in solid feel core cuts harmful miscellaneous vibration at impact. Solid feel core is carried in all racquets manufactured in Japan.
Combines solid hitting feel and quick swing.
ASTROX 77 uses a world’s-first, new dimension graphite material, Namd, which greatly improves the adhesion of the graphite fibers and resin by attaching nanomaterial directly to the graphite fiber.
In high performance racquets, it is common to combine nanomaterials with resin that connects graphite fibers, but in Namd, nanomaterials are directly adhered to the graphite fibers and resin is greatly increased. This major improvement produces a shaft that flexes and stores energy, delivering explosive force on impact with the shuttle.
New Frame Design And Racquet Length
Making the whole frame flexible allows the“ASTROX 88 S”to hold the shuttlecock for accurate control, while the“ASTROX 88 D” has more flex in the upper part of the frame transmitting maximum power to the shuttlecock to break through the opponents. In addition the overall length of the“88 S” is only 5mm longer, which enhances both accuracy and power while the“88 D” is 10 mm longer to provide powerful attacks.
New Enargy Boost Cap
The new shape allows the shaft to flex, which ensures the maximum effect of “Namd(more flex and faster kick-back graphite material)” and stabilizes the racquet face by preventing the shaft twisting, increasing control
Rotational Generator System
By applying the counterbalance theory, weight is distributed throughout the grip end, frame top and the joint for maximum control. The transition to the next shot can be performed smoothly with a rapid succession.
NEW Built-In T-Joint
‘NEW’ Built-in T-Joint is manufactured from a special lightweight plastic combined with epoxy resin and foaming agent that enhances quality and performance by increasing the stability of the shuttle on the string bed and through the air.
NANOMETRIC* improves the bonding strength between the carbon fibres enabling us to take racquet shaft construction to another level. By reducing the amount of carbon in the shaft to make it 60%* thinner than a conventional racquet whilst retaining stiffness, Yonex has created a revolutionary lightweight racquet with lightening head speed and control.
*NANOMETRIC is the new material which applies the NANOALLOYTM Technology of Toray Industries, Inc.
