At its core, the Yonex Astrox 99 Pro is a testimony to innovation, with a series of upgrades that set it apart from its predecessors. The racket features a fully recessed frame profile, making it nimbler and quicker to handle than the original Astrox 99. This agility is further accentuated by a slimmer shaft and a new streamlined cap at the top of the handle. However, agility doesn’t come at the cost of sturdiness. The Astrox 99 Pro showcases a slightly thicker frame than its previous iteration, harmoniously paired with a fresh isometric shape frame design, ensuring a balanced blend of power and control. And for those who prioritize grip, the racket delivers a longer wooden handle, standing at 17.3cm—a notable enhancement from the 16.5cm in the last generation.

The aim of this blog review is twofold. Firstly, it seeks to delve deep into the performance metrics of the Astrox 99 Pro, analyzing its suitability for both singles and doubles play.

Additionally, a side-by-side comparison with the older original Astrox 99 will offer readers a clear perspective on the evolution and advancements of this series.

For this review, the spotlight is on the 4U version of the Astrox 99 Pro, strung meticulously with BG80 strings at a tension of 27lbs, ensuring the observations and insights shared are precise and authentic.

Technology Changes and Improvements

The Yonex Astrox 99 Pro isn't just a testament to evolution, but a showcase of groundbreaking technological advancements aimed at enhancing a player's game. Here's a deep dive into the key technological changes and their potential impact on gameplay:

  1. Larger Grommets for Enhanced Shuttle Hold The Astrox 99 Pro features larger grommets, designed with the intent of increasing the shuttle's hold time on the racket. This innovation promises players enhanced control, allowing for superior shuttle placement. However, it's worth noting that during our rigorous testing, this distinctive feature wasn't as pronounced as one might expect. It's plausible that only players at the international level, with their refined senses, might discern this subtle difference.

One annoying issue was the strings tends to move far more than usual during gameplay - however it has no impact on performance.

  1. Slimmer Shaft for Swifter Responses The racket now boasts a slimmer shaft, measuring at a diameter of just 6.6mm, a noticeable reduction from its predecessor. This design change translates into faster swing speeds. The Astrox 99 Pro excels in high-pressure situations, providing players with that crucial split-second advantage to turn the tide in their favor.
  2. Power Assist Bumper: A Game-Changer One of the standout features of the Astrox 99 Pro is the introduction of the power assist bumper. Positioned strategically at the 12 o'clock section of the racket, this bumper concentrates the swing weight onto the racket's head, ensuring an efficient power transfer. Yonex's claim of it being 55% heavier than traditional grommets across the eight holes it spans underscores its significance.

  1. Prolonged Shuttle Hold with Namd Material Yonex's pursuit of perfection is evident in their endeavor to increase the shuttle's holding time on the racket. The Astrox 99 Pro employs the Namd material throughout its frame, combined with larger diameter grommets situated around the 3 and 9 o'clock sections. According to Yonex's internal testing, this results in an impressive near 10% increment in shuttle holding time when compared to the previous generation of Astrox 99.

The amalgamation of these technological upgrades positions the Astrox 99 Pro as a formidable contender in the world of badminton rackets, promising players an edge in their pursuit of excellence.

Gameplay Experience with the Racket

Front Court Performance 

In the realm of front court plays, the Astrox 99 Pro offers an average performance when compared to its siblings in the Astrox series. This is likely due to its heavier balance point. While executing net shots, the racket smoothly interacts with the shuttle, offering a tactile touch. However, cross-nets can strain the arm a tad more than desired. Particularly in doubles, during rapid rallies at the front, the racket falls short of expectations, especially when compared to the performance of the Astrox 88s Pro. For its front court prowess, the Astrox 99 Pro scores a 6.5/10.


Defensively, the 99 Pro shines with stability. If you have a penchant for head-heavy rackets and desire unwavering racket face stability during shots, the Astrox 99 Pro won't disappoint. In singles, the defence feels fluid, but the racket's heavy balance becomes a discernible challenge in doubles. Under duress, the racket lags in recovery, posing potential challenges for doubles players. It earns a score of 7/10 in defence.


Power is the arena where the Astrox 99 Pro truly dominates. It stands out as the powerhouse within the new Pro range. Smashes emanate with minimal effort, and even half-smashes pack a punch. Overhead clears and backhand clears are executed with ease. For its sheer power capabilities, the Astrox 99 Pro boasts a score of 9.5/10.

Comparison with the Original Astrox 99

The Astrox 99 Pro distinguishes itself from its predecessor in terms of an enlarged sweet spot and increased speed. The fully recessed frame accentuates the racket's speed, making it superior to the original Astrox 99. The augmented gaps between strings in the central region, combined with the larger grommets, enhance the sweet spot, ensuring better shuttle hold. Contrary to the original model, which felt a tad overburdened, the 99 Pro strikes a balance between power and manageability, suitable for intermediate and advanced players.

Singles or Doubles?

Crafted with a head-heavy balance and stiffness, the Astrox 99 Pro is tailored for singles players. The dynamics of singles allow players the luxury of full swings, where the 99 Pro can be harnessed to its full potential. Doubles players might find it challenging due to its slower speed. This observation is corroborated on the world circuit, where singles stalwarts like Kento Momota prefer the 99 Pro, while it finds limited takers among doubles players.

    Conclusion: Is the Astrox 99 Pro the Right Racket for You?

    Deciding on the perfect racket is always a balance of power, agility, and personal playing style. The Astrox 99 Pro, with its distinct features, can be a challenge to wield for some. For dedicated singles players, it stands out as an impeccable choice, delivering unmatched power across the court. However, for those who oscillate between singles and doubles, its versatility might fall short.

    If you find yourself often transitioning between game styles, or if you're in search of a racket that's more forgiving, there are alternatives within the Astrox range worth considering. The Astrox 77 Pro or the Astrox 88d Pro(read our review) might offer the adaptability and ease-of-use that the 99 Pro doesn't prioritize.

    Ultimately, the right racket complements your strengths, mitigates your weaknesses, and aligns with your playing style. So, while the Astrox 99 Pro is undoubtedly a masterpiece in its own right, it's crucial to assess whether it's the masterpiece that aligns with your game.
