The ASTROX series is developed to meet the demands of aggressive attacking play, taking the point to your opponent with relentless steep attacks.

The Rotational Generator System perfectly distributes weight through the grip end, frame top and the T-joint for maximum control, enabling smooth transitions between shots, in a rapid succession. Namd, a revolutionary graphite that produces more flex and faster snapback for imposing power.


1. Isometric

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.

2. Advanced 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.

3. Built-in T-Joint

Moulded deep into the layers of graphite where the frame connects with the shaft, the YONEX Built-in T-Joint creates a durable and high-strength one-piece frame that is torque-free.

4. Control Support Cap

The control support cap provides an 88% wider flat surface compared with an ordinary racquet for easier gripping, fast follow-through and the sharpest maneuverability.
