Comparing the Astrox 77 to the New Astrox 77 Pro

In my previous rackets reviewing the Yonex Astrox 77 badminton racquet, i covered the key features and performance of this popular all-around model. Now with the release of the updated Astrox 77 Pro, many players are wondering exactly how the two compare. Here I’ll highlight the main similarities and differences between the Astrox 77 and Astrox 77 Pro:

Visual Differences

The Astrox 77 originally came in bright yellow and metallic blue color options. The new Astrox 77 Pro introduces a glossy “High Orange” scheme with purple decals. While the color change may not affect performance, the Pro has a sleek, professional aesthetic.

The Astrox 77 Pro racket Yonex also now features the Energy Boost Cap Plus found on other high-end Yonex rackets. It has a flatter profile than previous generations for a cleaner look.

Flex Fuse Technology

A key upgrade not visible to the eye is the integration of Flex Fuse resin in the throat of the racket. This shock-absorbing resin enables better vibration damping for a more comfortable and arm-friendly feel on shots.

Measurable Specs

In terms of measurable specs like head size, weight, balance, and frame thickness, the Astrox 77 Pro remains very similar to the previous Astrox 77. The shaft diameter increased slightly from 7mm to 7.1mm but this minute change doesn’t impact performance.

Playing Experience

When play testing the Astrox 77 Pro against the Astrox 77, I found the Pro to feel marginally faster and softer. The Flex Fuse resin seems to add some extra flex and comfort. In terms of power and control, the Pro plays practically identical to the standard Astrox 77.

Overall, the Astrox 77 Pro retains the buttery smooth, easy playing characteristics of the Astrox 77. It provides a touch more speed and a softer, more arm-friendly feel. For Astrox 77 users happy with their current racket, the upgrade may not be warranted. But those seeking just a slight performance boost will appreciate the Pro edition.

Professional Stringing and Tension

I strung both rackets with my usual Yonex Aerobite strings at 27lbs mains and 29lbs crosses. Both rackets string up smoothly without any problems. Yonex suggests the same string and tension recommendations apply to the Pro as the original Astrox 77.

The Verdict by our Professional Stringer

Yonex succeeded in taking an already great all-around racket in the Astrox 77 and enhancing it just a bit further. While the upgrades aren’t huge, the Astrox 77 Pro offers incremental improvements in speed, power, and arm comfort. For new purchasers, it’s worth choosing the Pro. But Astrox 77 users shouldn’t feel pressured to switch unless seeking marginally more flex and responsiveness. Both versions of the Astrox 77 shine as ideal control-focused rackets suitable for club players to pros.

Let me know if you need any other specific comparisons between the Astrox 77 and Astrox 77 Pro! I’m happy to expand this section further with additional details and insights from play testing both rackets extensively.

Star Given and Review from Our Professional Coach and Stringer for Yonex Astrox 77 Pro

Eric’s Review: This new racket actually feels different compared to the first version of the Astrox 77. I prefer this one more due to its stiffness and repulsion, everything is just nice. At that time, everyone knew the Astrox 77 was merely a mid-range racket designed to support the Astrox 88D and Astrox 88S, and the Astrox 99 kept upgrading. Yonex’s marketing is quite impressive, to be honest. Fortunately, this racket really is not bad; it’s not too stiff like before, the head weight is just right, and it’s quite easy to generate power with a smash. You see, this racket is used by professional players, now so many players are using it, player like An Se Young, Chen Yu Fei, Muhammad Rian Ardianto, Fajar Alfian, Huang Ya Qiong, Huang Dong Ping. mostly women, and I don’t know why, but there must be a reason they favor this racquet. I also like the racket feels, perfect racket for women maybe, but I’m not a woman, haha.

As a professional badminton coach and stringer, the Yonex Astrox 77 PRO receives our rating of 4.0/5 stars as a top notch all-around racket. While it doesn’t match the plow-through power of the Astrox 88/99, it provides outstanding blend of speed, precision, repulsion, and arm-friendly comfort. The upgrades in the Pro version are relatively minor but still deliver a slightly faster, softer hitting feel. For intermediate and advancing players seeking an agile, forgiving racket to take their game to the next level, the Astrox 77 PRO is an excellent choice.

Frequently Asked Questions of Yonex Astrox 77 PRO

The Astrox 77 Pro has an even balance and all-around medium flex, giving it a very smooth and fluid feel on both forehand and backhand strokes. It provides a nice blend of power, control and stability without feeling too stiff or flexible. Many players describe the Astrox 77 Pro as buttery smooth and easy to swing.

The Astrox 77 Pro has an even balance, meaning the weight is distributed pretty evenly throughout the head and shaft. This gives it great versatility for different playing styles rather than an extreme head light or head heavy configuration.

With its forgiving sweet spot and fast maneuverability, the Astrox 77 Pro is ideal for intermediate players looking to advance their skills as well as developing juniors. The blend of control and power also suits competitive club players. It gives a bit more power than a beginner racket but doesn’t have the stiff feel some advanced rackets have.

The Astrox 77 Pro comes with a choice of 3 grip sizes: G4 (4 1/4 inches), G5 (4 3/8 inches) and G6 (4 1/2 inches). The grip size should be chosen based on the player’s hand size and personal comfort. Those with smaller hands may prefer G4 while larger hands suit G5 or G6.

The versatile and quick feel of the Astrox 77 Pro makes it a great option for both singles and doubles play. The fast swing and enhanced maneuverability help when moving around the court for singles. The enlarged sweet spot also provides the forgiveness needed at the net for doubles.
