Introduction

Having the correct badminton equipment is an essential part of a player’s identity. Each piece of equipment changes an aspect of the game and finding what fits your style is important to optimize your own performance and budget. In this post, we will focus on informing you about the tradeoffs between the different Yonex strings by comparing their statistics and price.

If you’re looking for information about shuttlecocks, I would highly recommend learning about the different properties about what makes a shuttlecock durable and consistent in different conditions. Getting the right shuttlecock for your situation can help make your game play more enjoyable and cost efficient. Take a look at our Complete Guide to Yonex Badminton Shuttlecocks (Feathered) to learn more.

Before diving into the details, you may be wondering why you should even care about strings. The string is a core part of any badminton player’s experience as it’s the part of the racket that actually makes contact with the shuttle. This means that the strings are highly responsible for the maximum potential of how well you can hit the shuttle – including both control and repulsion power. Hitting the shuttle in the same way with different strings at the same string tension can result in vastly different results. Even the smallest nuances in the properties of a particular string can be the difference between the shuttle landing in or out of bounds. Therefore, it is critical to find the correct string that compliments your play style and maximizes your potential.

String Properties

Yonex rates each of their strings in 5 different properties:

1. Repulsion Power
2. Durability
3. Hitting Sound
4. Shock Absorption
5. Control

Repulsion Power indicates the degree in which the string assists in pushing the shuttle outwards upon contact. The higher the repulsion power, the greater the force you will be able to generate with the string when you hit the shuttle. This is due to a trampoline effect that occurs when the shuttle contacts the string bed and is subsequently ricocheted forward.

Repulsion power typically holds an inverse correlation to the durability of the string since strings with high repulsion power tend to be thinner and thus easier to break through.  Players should be wary that repulsion power is also inversely correlated with string tension. This means that lower string tension results in higher repulsion power.

An Inverse Correlation is a relationship between 2 variables which move in opposite directions. For example, since repulsion power and durability are inversely correlated, an increase in repulsion power will result in a decrease in durability.

Durability indicates the resilience of the strings against wear, pressure, and damage. It is natural for strings to wear down after repeated use from the strings sawing against each other due to hitting the shuttle. The time it takes for the string to break depends on the thickness and material of your strings. Typically, the thinner the string is, the quicker it is to break due to repeated use.

Hitting Sound indicates how much noise is made when a shuttle is hit. This helps players gauge if they hit the shuttle properly in the sweet spot or not. If the sound is clear and pristine, it indicates that a clean shot was hit while a muffled sound indicates a mishit. The higher the hitting sound, the easier it is to tell the difference between clean and mishit shots.

Shock Absorption indicates how well the string copes with the force of a shuttle hitting your racket. When the shuttle contacts the string bed of a racket, the string and racket will vibrate to absorb the shock of the shuttle. Any remaining vibrations will be absorbed by the player’s arm and body. This phenomenon causes a delay to the player as he/she will need to recover from the shock. The better a string is at absorbing shock, the fewer the vibrations that will be transferred to the player, and subsequently the faster the player will be able to recover from the shock.

Control indicates the degree to which, upon execution of a hit, a player is able to influence the shuttle’s flight. Control is generally inversely correlated to repulsion power, as a reduction in the trampoline effect will allow players to hit with more accuracy and precision.

String Products

Here we will introduce each of the Yonex badminton string products along with their product specific attributes such as core, outer, coating and gauge. A summary of all the string products can be found below the string profiles.

If you’re looking for some alternative options for badminton strings, I’d recommend taking a look at Victor and Ashaway strings. They have their own proprietary technology that differs from Yonex’s. You can compare for yourself over at The Complete Guide to Victor and Ashaway Badminton Strings.

If you’re interested in other badminton products, I highly recommend checking out our Badminton Equipment page where we gathered all of our product posts in one easy place for you to access so that you can make an informed decision before any purchase.

Aerobite Boost

The Aerobite Boost is the newest addition to Yonex’s line of hybrid strings, where a thicker 0.72 mm mains is paired with thin 0.61 mm crosses. The Vectran™ Super Fiber core and oval-shaped outer of the mains minimizes the loss of energy upon impact, translating to explosive repulsion of the shuttle. The thin cross strings increase the spin and speed of the shuttle, making the Aerobite Boost a prominent choice for players seeking tighter hairpin drops and steeper cut smashes.

Core	Mains: High-Intensity Nylon Multifilament, Super Fiber: Vectran™
Outer	Mains: High Polymer Braided Nylon Fiber, Oval-Shaped
Coating	Mains: Polyurelthane
Gauge	Mains: 0.72 mm Crosses: 0.61 mm
Amazon	Gray/Yellow
Racquet Depot	Gray/Yellow | Gray/Yellow (reel)
Yumo Pro Shop	Gray/Yellow

Aerobite

The Aerobite is the first ever string that uses different materials and gauges for its mains (vertical strings) and its crosses (horizontal strings)! The mains are 0.67 mm thick and the crosses are 0.61 mm thick. Designing it this way lets it be optimized for both repulsion power and control, but lacks in durability. Recommended for serious players who want the extra boost in performance.

Nanogy 99

The Nanogy 99 uses a rough braided fiber that is designed to help maximize the player’s control over the shuttle. This is an excellent choice for players who want to be able to place the shuttle in precise locations without forfeiting much in terms of repulsion power or durability. Great for intermediate to advanced players.

Skyarc

Skyarc is Yonex’s latest edition to their strings that boasts high repulsion power. This string is geared towards younger players, older players, and beginner/social players who may not yet have the power or techniques themselves to send the shuttle deep into their opponents’ court. The larger sweet spot provided by the strings makes mishits more forgiving for the target user. The high shock absorption allows players to play for long periods of time without experiencing irritation to their wrists.

The strings do not provide great feedback upon contact with the shuttle, which diminishes the feeling and control on the shuttle, despite Yonex’s rating on the Skyarc at 10. As such, the Skyarc may not be the most suitable for advanced players.
