Adult Unstrung Tennis Racket RF 01 300 g - Black

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 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.

Balance (unstrung racket)

31.5 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 (head light or handle heavy), the easier the racket will be to handle but you'll have less power and stability.

Head size

632 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.

Stiffness

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 =



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

68.58 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 (in mm)

Cross section (in mm): 23.2 mm / 24 mm / 22 mm

Braid 45 technology

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

Glide guard

The bumper guard and grommets are smooth, contributing to the racket head's overall speed.

Feel fill

Inside the racket is PU-injected foam for vibration dampening.

SABR

SABR frame design for excellent versatility, allowing for changes in rhythm, rotation and direction.

Design

Simple and essential, worked down to the last detail with Roger Federer.
