The ASTROX series will help you take the point to your opponent with devastating smashes and steep attacks. Developed for aggressive play, ASTROX racquets are designed to dominate every match. It starts with the application of counterbalance theory to racquet design. Our Rotational Generator System distributes the weight throughout the grip end, frame top and the joint for maximum control, enabling you to transition between shots smoothly, in rapid succession. Namd, a graphite that produces more flex and faster snapback, lets ASTROX racquets unleash dramatic power. Innovative design like the new Energy Boost Cap maximize Namd’s advantage, giving you more flex on the front of the shaft while helping to stabilize the racquet face on every shot. The original ISOMETRIC frame has also evolved into a more ISOMETRIC shape, expanding the sweet spot. Designed for reduced power loss from off-center shots, the 2.9% larger sweet spot increases power. Seize the moment on court and overpower the competition with ASTROX series racquets.
Enlarged Sweet Spot
ISOMETRICTM technology continues to help the world’s greatest players achieve global success.
Developed over 30 years ago, the ISOMETRICTM design increases the sweet spot by 7%*. Compared to a conventional round frame, a square-shaped ISOMETRICTM racquet generates a larger sweet spot by optimizing the intersection of the main and cross strings.
ISOMETRICTM delivers greater control without sacrificing power. ISOMETRICTM is a Trademark of Yonex CO., LTD.
*Tested by Yonex
The iconic ISOMETRIC head shape is enhanced for a larger, more forgiving sweet spot. Frame sides are strategically reinforced with wider areas for a stronger construct.
2. “Rotational Generator System” has evolved further
Counterbalanced Weight Distribution
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.
3. Revolutionary New Graphite Namd
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.
4. Super Slim Shaft
Reduced Air Resistance
The slimmest racquet ever produced by YONEX vastly reduces air resistance whilst providing maximum feel.
5. AERO+BOX Frame
Combines solid hitting feel and quick swing.
6.Energy Boost CAP PLUS
Uniquely shaped cap which maximizes shaft performance. The front allows the shaft to flex, while the sides arch-shaped curve stabilizes the racquet face by preventing the shaft from twisting.
