Yonex Astrox 99 Pro [White Tiger]

*This is an unstrung racket. Please choose add-on string if needed, thank you.

Designed with Kento Momota

The ASTROX 99 is a head-heavy power racquet, boasting the heaviest swing weight of the ASTROX series. Its known to generate a single, powerful smash, often too heavy to be speedy in recovery. In response, Yonex worked hand in hand with Kento Momota to craft a racquet that would give him both power and the ability to convert defensive plays into offense; the result is an improved ASTROX 99 where decisive power is accompanied by extended shuttle hold for enhanced defensive shot-making.

The new ASTROX 99 is equipped with the POWER-ASSIST BUMPER, a tungsten-infused weighted bumper installed at the top of the frame transferring additional weight to the shuttle for more powerful smashes. To enhance defensive shot-making, Wide Diameter Grommets are strategically placed on the frame sides, allowing strings to shift at impact for emphasized shuttle pocketing. The iconic ISOMETRIC frame has been modified by strengthening frame corners to adjust the shape and expand the sweet spot.

INNOVATIONS

POWER-ASSIST BUMPER

Boosted power with a tungsten-infused weighted bumper, adding 55% more weight* than conventional grommets. The POWER-ASSIST BUMPER enhances the Rotational Generator System, quickly transferring more weight to the shuttle.

*Measured by Yonex

Rotational Generator System

Intricate weight distribution technology designed with the counterbalance theory that allows head-heavy racquets to recover faster between shots. By employing the VOLUME CUT RESIN and POWER-ASSIST BUMPER, the new ASTROX 99 models have a further refined Rotational Generator System where intricate weight distribution can be taken to the next level.

Wide Diameter Grommets

Control the shuttle-release timing with larger grommets designed for more string movement, extending the shuttle contact time.

Modified ISOMETRIC frame shape

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.

Rotational Generator System

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.

Solid Feel Core

Cuts Vibration

Reduces vibrations traveling down the shaft for improved comfort.

Extra Slim Shaft

Thinnest, Strongest Ever Produced by Yonex

Designed to slice through the air, generating speedy power.
