Adult Tennis Racket Pro Staff 97 LS V14 290 g - Black

290 g Weight: 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 it transfers to the ball, but the harder it is to handle. The lighter the racket, the easier it is to handle, but the trade-off is less power.

626 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 greater the feeling of control, but you sacrifice some power and forgiveness.

Some of the graphite fibres have been braided at a strategic 45-degree angle for power, penetration and stability

Denser string pattern at the sweet spot for improved control.

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

Reverse string pattern (more vertical than horizontal strings), more space between the strings to increase string movement and maximise spin.

32.5 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.

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.

18 x 16 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.

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.
