Power is an integral characteristic of the Astrox family. For racquets in the Astrox line-up, the head-heavy nature of the series means strength is pertinent to unlocking the raw power. The brand new Astrox 77 is different — power is effortless and accessible to all. The new Astrox 77 is designed with a mid-flex shaft and a maneuverable, slightly heavy head which grants extra power for a wide range of players from intermediate to advanced. These second-generation sports improvements in the hitting feel by enhancing shock absorption, and power by balancing snapback and flex.
The original Astrox 77 is designed for intermediate to advanced players looking to dominate the court with steep smashes. It is equipped with the Rotational Generator System that enables quick recovery for a continuous stream of powerful attacks. The racquet utilizes Namd throughout the shaft producing more flex and a faster snapback.
The new Astrox 77 is a further evolved version of its predecessor, featuring new technologies for better performances and a 2.9% increase in smash power. The joint at the bottom of the frame is composed of a new resin material, Flex Fuse, which combines a shock-absorbing material with base resin for a softer feel on impact. The new elongated shaft is equipped with Namd, a carbon-graphite material that generates quick snapback to accompany the extra flex. The addition of the E.B.CAP PLUS (Energy Boost Cap Plus) is used for the further snapback.

A world-first, new dimension graphite material, Namd, 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.
2. AERO+BOX Frame
Combines a solid hitting feel and quick swing.
ISOMETRIC technology continues to help the world’s greatest players achieve global success.
Developed over 30 years ago, the ISOMETRIC design increases the sweet spot by 7%*. Compared to a conventional round frame, a square-shaped ISOMETRIC racquet generates a larger sweet spot by optimizing the intersection of the main and cross strings.
ISOMETRICTM delivers greater control without sacrificing power.
*Tested by Yonex
4. 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.
5. Super Slim Shaft
The slimmest racquet ever produced by Yonex vastly reduces air resistance whilst providing maximum feel.
6. Energy Boost CAP PLUS
A uniquely shaped cap that maximizes shaft performance. The front allows the shaft to flex, while the side arch-shaped curve stabilizes the racquet face by preventing the shaft from twisting.
