- ISOMETRIC™
The ISOMETRIC™ equalizes the length of the main and cross strings in the string-bed, enlarging the sweet spot for more consistent accuracy even on off-centre hits.
- 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.
- 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.
- AERO_BOX Frame
Combines solid hitting feel and quick swing.
- 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 rapid succession.
- Namd
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.
- Energy Booster Cap
The new shape allows the shaft to flex, which ensures the maximum effect of “Namd[1](more flex and faster kick-back graphite material)” and stabilizes the racquet face by preventing the shaft twisting, increasing control
- Super Slim Long Shaft
The slimmest racquet ever produced by Yonex vastly reduces air resistance whilst providing maximum feel.
- NANOMETRIC™
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.
*approximate measurement when compared to a conventional racquet shaft, tested by Yonex.
