Length
675 mm, 10 mm longer. The length of an adult's racket is measured in millimetres and ranges from 660 mm to 680 mm. In fact, the shaft is the only part that changes in length. A shorter shaft will be more manoeuvrable and provide a better feel. A longer shaft will offer increased inertia for added power.
Original strings
The rackets come factory strung with Yonex strings with a 0.70 mm gauge (not available from stores). Only very high-end rackets made in Japan are factory strung with BG65 strings with a 0.70 mm gauge.
Flexibility
Semi stiff.
Flexibility is defined as the shaft's capacity to bend while hitting. Shafts can range from flexible to rigid.A flexible shaft is more forgiving and will help you hit the shuttlecock further, although your shots will be slower. While a rigid shaft provides better propulsion, it requires a fast swing and is less forgiving.
Pre-strung and recommended
Factory tension: 8-10 kg.
Tension recommended by the brand: 8-12 kg.
The rackets come with a tension that ranges between 8 kg and 10 kg, depending on tension losses that occur during transport. Each brand indicates a recommended tension, generally somewhere between 8 kg and 12 kg. This is to prevent the string or frame from breaking while stringing or hitting. Finally, some rackets have a reinforced frame that can withstand a tension of up to 16 kg.
About the ASTROX series
The ASTROX (which replaces the VOLTRIC range) is a powerful racket that meets the needs of players with an aggressive offence. These rackets have a head-heavy balance so you can attack with confidence and put away every smash.
Composition
graphite.
The price of a badminton racket is affected by its composition. Steel and/or aluminium rackets are sturdy, heavy and better suited to recreational use. Graphite/aluminium and full graphite rackets are lightweight and perfect for beginner and intermediate players. Rackets made from high-modulus graphite and other materials like tungsten are designed for advanced players.
Rotational Generator System
By applying the principle of counterbalance, weight is distributed from the end of the handle towards the head for maximum control. The transition to the next shot can be done smoothly and in rapid succession
Weight
83 g - 4U (80-84 g). The weight (actually the mass) is measured in grams. A badminton racket's weight ranges from 60 grams to over 100 grams and is classified into different "U" weight ranges. The lighter a racket is, the more manoeuvrable and comfortable it will be. It's also easier to swing and faster, although less powerful. On the other hand, a heavier racket will be more powerful but less comfortable.
ENERGY BOOST CAP PLUS
The new top cap maximizes shaft performance.
The front optimizes shaft flex and allows for maximum use of the Namd material. The arch-shaped curve stabilizes the racket's frame, preventing the shaft from twisting
TUNGSTEN
Material designed to create a head heavy balance for added power
NANOMESH NEO
First generation graphite makes the frame more durable and flexible.This material increases shaft flexion for maximum power and a quick recovery after each hit
Grip size
G5 = small (80‒84 mm). Grip size is measured in millimetres. Grip size ranges from 75 mm to over 90 mm and is categorized into size ranges expressed in "G". While a larger handle is easier to hold, many players have difficulty changing their grip. A smaller handle is easier to wield and lets you put more power on the racket by using your fingers.
String pattern: mains * crosses,

B = bottom, T = top
22*21.
4-knot stringing instructions
Mains: start from top centre and string down to B10 (skip holes B9, T8, T10 and T12). Go through B14 towards T15, then go back to T13, down to B12 and finish by tying off at B8.(same other side)
Crosses: Make a knot at B6 and start crosses from B9. Keep on stringing the crosses until T8 (skip holes B10, B12, T11, T9 and T7) and finish by tying a knot at T5.
ISOMETRIC
The Isometric design increases the sweet spot by 7%*. A square-shaped Isometric racket creates a larger sweet spot than a classic round frame by optimizing the intersection of the mains and crosses.
Slim shaft
The thinner shaft enables it to slice through the air more easily, generating a faster, more powerful shot.

Balance
Head heavy.
Balance refers to the racket's weight distribution. It is indicated in millimetres and is measured from the base of the handle to the balance point. A head light racket will be more manoeuvrable and reactive, making it perfect for defensive and doubles players. Head heavy rackets will provide better power, the ideal choice for offensive players. However, they can feel heavy and difficult to swing.
AERO+BOX Frame
The frame combines an aerodynamic front profile with an extra stiff rear profile for a faster swing and a solid, stable feel when hitting the shuttlecock.
BUILT-IN T-JOINT
The built-in T-joint reinforces the connection between the shaft and frame while reducing twisting for greater control
