Technology
- Rotational Generator System + Power-Assist Bumper
Distributes weight across the grip end, frame top, and joint for smooth transitions and powerful attacks. The bumper adds weight on top and reduces air resistance for better energy transfer.
- 2G-Namd™ Flex Force (frame & shaft)
A new-generation graphite that flexes and snaps back rapidly, thanks to carbon nanotubes that improve energy storage and return.
- LIGHTWEIGHT END CAP
- A lighter end cap shifts balance toward the head, making this one of the most head-heavy models and aiding smash power.
- CONCENTRATED SWEET SPOT FOR POWER
Meeting the demand of heavy smashers with an increased shot power
- SHOT INFORMATION CONNECTOR
Provides confidence with increased shot information by extending contact time between the shuttle and the string to transfer information without loss
The all-new ASTROX 99 reflects Yonex’s enduring pursuit of innovation — empowering badminton players everywhere to redefine the limits of power, precision, and performance on court.
