  • For Powerful Doubles & Singles Play
  • 4U Weight
  • Medium Flex
  • Head Heavy Balance
  • Used by Chen Yufei
  • Made in in Japan

The Yonex Astrox 77 Pro 4U badminton racket is the latest version of this popular model, suited to players seeking power but in a more user friendly frame than higher spec versions in the Astrox range.

The Astrox 77 Pro is the weapon of choice for Olympic singles champion Chen Yufei.

Featuring:

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.

AERO+BOX Frame - Combines solid hitting feel and quick swing.

ISOMETRIC - ISOMETRIC technology continues to help the world’s greatest players achieve global success. Developed over 30 years ago, the ISOMETRIC design increases the sweet spot by 7%*. Compared to a conventional round frame, a square-shaped ISOMETRIC racquet generates a larger sweet spot by optimizing the intersection of the main and cross strings. ISOMETRIC delivers greater control without sacrificing power.

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.

Super Slim Shaft - Reduced Air Resistance. The slimmest racquet ever produced by YONEX vastly reduces air resistance whilst providing maximum feel.

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.

*Please be aware that Yonex no longer supply a cover for this racket due to an innitiative to reduce waste and landfill.

BUYING GUIDE

Badminton Rackets Buying Guide

The key question to ask firstly is what style of player are you, or what type of player do you want to become?

  1. Power Attacking
  2. All Round
  3. Fast Reactions to Rallies
  4. Control and Touch, by moving players around the court to create space

As a general guide for your playing style below is the kind of racket you'll want to look at purchasing:

Playing Style Racket Balance Racket Flexibility Racket Weight
Power Attacking Head Heavy Stiff 85g – 89g (3U)
All Round Balanced Medium 80g – 84g (4U)
Speed & Fast Reactions Head Light Medium 79g or below (5U and up)
Control & Touch Head Light Hi Flex 79g or below (5U and up)


In simple terms is means this:
Player with Explosive Backswing Hitting = Stiffer Shaft needed as it'll unload faster for more power.
Player with Slower Backswing Hitting = More Flexible Shaft needed so that it'll unload fully at impact.

If you're still unsure what to choose for yourself, we'd recommend going for a medium flex badminton racket to minimise the chances of choosing incorrectly what's right for you.

Weight:

Weight can make a real difference to reaction speeds, and power behind the hit of a shuttle. Too light a racket and it won't go far or powerful enough. However too heavy a racket and you'll find you'll be reacting too slow in fast flat rallies, where reaction speed is everything.:

Most rackets are weighted around 3U (85-89g) or 4U (80-84g), this is because it's a good weight balance for players to hit hard and also be able to react fast too.:

Typically singles players will use heavier rackets 3U (85-89g), this provides the player with more stability and accuracy, with a little more weight for power behind it, without compromising on racket speed too much, as quick racket head speed isn't needed as much in the singles game:

Doubles players however will usually want lighter rackets, the most popular weight for this being 4U (80-84g), this is because the Badminton Racket will offer more speed and quicker reactions in around the net and for defence against smashes.:

Racket Strings Used & Tension:

Again like the grip, this is customisable on any racket. However do look out for racket tension ranges on the product as this could potentially limit your ability to have the racket strung at a desired tension.:

For a full breakdown on strings and tensions, see our buying guide specifically on this.:

To put it simply however, if you're unsure what to choose when buying a racket you like, either go for the “Original Strings” option or “Stringers Professional Decision” for which we'll choose the string that best suits getting the maximum performance out of the racket for you.:

Yonex Astrox 77 Pro 4U - Decent

Whilst it pained me to buy this at full price, it is a very decent racquet - Used for doubles and all-round play which it is extremely good for. I wouldn't recommend as a power racquet for singles unless you are at an Elite level.
