Racket Astrox 7 DG - Black / Blue

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.

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.

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.

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.

Composition

HM 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.

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.

Grip size

G4 = medium (85‒89 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.

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.

Pre-strung and recommended

Factory tension: 8-10 kg.

Tension recommended by the brand: 8-16 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.

String pattern: mains * crosses, Stringing instructions for 76 holes B = bottom, T = top

22*21.

4-knot stringing instructions

Mains: start from top centre and string down to B9 (skip holes T8 and T10). Go through B12 towards T15, then go back to T13, down to B10 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 T11 and T9) and finish by tying a knot at T5.

DG FRAME

More robust frame materials for higher tensions

Nanomesh Neo

First generation graphite makes the frame more robust and flexible.This material increases shaft flexion for maximum power and a quick recovery after each hit

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.

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.

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

Control support cap

The top cap is 88% wider and flatter than on an ordinary racket, which improves grip and gives players better control.

Slim Shaft

The thinner shaft enables it to slice through the air more easily, generating a faster, more powerful shot.

TUNGSTEN

Material designed to create a head heavy balance for added power
