Adult 300 g Unstrung Tennis Racket Ultra 100 V4 - Blue

Weight (unstrung racket)

300 g.

Weight: The weight is measured in grams. Just like balance point and length, the weight impacts a racket's swing weight 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

70 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 = 285

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.

Stringing:

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): 23/26/23

FORTYFIVE

The patented FortyFive technology - an update to Carbon Mapping - gives an unrivalled combination of flex and stability.

POWERPROFILE

As a key technology in the new Ultra range, PowerProfile includes three geometric improvements designed to enhance stability and better leverage the power produced by the strings.

INTEGRATED PWS

INTEGRATED PWS takes the volume of the original PWS (Perimeter Weighting System) and distributes it over a larger area of the strings to maximise their power while maintaining stability.

SWEET SPOT CHANNEL

The Sweet Sport Channel is a cavity on the side of the frame that extends the cross strings by 3.5 mm for more power and responsiveness.

INVERTED POWER RIB

The throat geometry of the Inverted Power Rib enhances torsional stability for more power and reduced frame twisting.
