YONEX Adult Tennis Racket Ezone 100 300g

This racket was designed for advanced tennis players looking for a powerful, stable racket.Racket sold unstrung.The 7th generation Yonex EZONE 100 is just as powerful and stable. Its “ISOMETRIC” frame shape, a signature of Yonex rackets, also ensures good control.

Weight (unstrung racket)

300 g.
Weight: The weight is measured in grams. Just like balance point and length, the weight impacts a racket’s swingweight and therefore its manoeuvrability, stability and ability to transfer energy to the ball (power). The heavier the racket, the more power you’ll get, but the harder it will be to handle. The lighter the racket, the easier it will be to handle, but the trade-off is less power.

Balance (unstrung racket)

32 cm

Balance: This is the racket balance point, measured in centimetres from the bottom of the shaft. The higher the number (head heavy), the more powerful and stable upon impact the racket will be. However, it will also be harder to manoeuvre. The smaller the number (grip biased or handle heavy), the easier the racket will be to handle but you’ll have less power and stability.

Head size

645 cm²

Head size: This is the surface area of the racket head size measured in squared centimetres. It has an impact on the racket’s forgiveness and power. The larger the head size, the more powerful and forgiving it is, but the downside is less control. The smaller the head size, the more control you’ll get, but you’ll have to sacrifice power and forgiveness.

Stiffness

67 Ra
Ra: This refers to the racket’s stiffness, i.e. how much it bends under the impact of the ball. The stiffer the racket (the higher the Ra), the less it bends. The energy lost on impact is minimised and returned to the ball via the strings. Generally, a stiffer racket offers greater power.

Swingweight (unstrung racket)

SW = 292
Swingweight: This indicates how easy a racket is to handle and its ability to transfer energy to the ball (power). The higher the swingweight, the more powerful the racket, but also the harder it will be to handle. Conversely, the lower the swingweight, the easier the racket will be to handle, but the trade-off is less power. The swingweight is derived from a combination of the racket weight, balance and length.

String pattern

16 x 19

String pattern: This is the number of mains (vertical strings) x the number of crosses (horizontal strings). The more strings the pattern has, the more “closed” it is; the fewer it has, the more “open” it is. A more closed string pattern offers a greater feeling of control, but less power and spin. A more open string pattern provides more power and spin, but less control.

Length

68.5 cm

Length: This is the length of the racket from the bottom of the grip to the top of the head. It is measured in centimetres. The longer the racket, the more power you’ll get, but the flip side is that it will be harder to handle. The shorter the racket, the easier it will be to manoeuvre, but you’ll have to give up power.

Cross section

Cross section (in mm): 23,8/26,5/22,5

Isometric

Developed over 30 years ago, the ISOMETRIC design increases the sweet spot by 7%*. Compared to a classic round frame, an ISOMETRIC racket with a square shape generates a larger sweet spot by optimising the intersection between mains and crosses. ISOMETRIC offers better control without sacrificing power. ISOMETRIC is a commercial brand of Yonex CO., LTD.

Liner Tech

The newly-designed eyelets allow for greater string movement on off-centre strikes.

VDM Vibration Dampening Mesh

For greater feel and precision, a stretch mesh material is rolled around graphite in the handle to filter out undesirable vibrations.

2G NAMD SPEED Technology

High modulus graphite fibres are connected to a carbon nanotube structure (CNT), reducing energy loss, which transfers energy into a rapid return.

Namd is a technology developed by Nitta Co., Ltd. to uniformly distribute the carbon nanotubes in the carbon fibre composites.

O.P.S (Oval Pressed Shaft)

The Oval Pressed Shaft (OPS) is designed to provide greater spin, control, and sensation. The racket’s frame flexes on impact, increasing contact time and minimising vibrations.

AERO SHAPE DESIGN

An inverted frame design with one thinner side to the racket for greater flexibility.

Shaft design

A thicker heart structure with a convex design reduces undesirable racket torque on off-centre strikes for greater power.
