Wilson Ultra Power 21 children's tennis racket blue WR118910H (WR118910H)

The Wilson Ultra Power Jr 21 children's tennis racket has been designed for young tennis players, providing support in learning the correct technique and maximum comfort during play. The construction of this model uses key technological solutions that cater to the needs of children aged 5-6 years, ensuring appropriate maneuverability and control over their shots.

Durable aluminium material

The main frame of the Wilson Ultra Power Jr 21 is made of aluminium, which ensures adequate stiffness while being lightweight, making it easier for younger players to handle the racket. Aluminium guarantees good resistance to mechanical damage, which is particularly important for equipment designed for children. The stability of the construction affects the precision of shots and allows for long-lasting usage under intense training conditions.

Advanced technologies supporting play

The racket is equipped with Stop Shock Sleeves technology, which effectively dampens vibrations and increases comfort during ball striking. The C Beam frame profile enhances the stability of the construction and allows for better control during play. The use of AirLite Alloy material and the AirLite Bumper Guard further increases the durability of the frame and protects it from damage during intense rallies on the court.

String pattern and racket balance

The Wilson Ultra Power Jr 21 features a 16/16 string pattern that promotes spin generation and easy acceleration of the ball. The factory stringing ensures readiness to play immediately upon removal from the packaging, and the balance towards the grip (255 mm) improves maneuverability and facilitates precise shot execution, which is especially important for children starting their journey with tennis.

    A handle is a grip that a player holds in his hand. The size of the handle is determined by its circumference. The handle sizes of tennis racquets are marked in two ways:

    Method 1: To check if the racquet has the correct handle size, grasp it as shown in the figure above. If the index finger of the other hand fits exactly between the ball of the thumb and the tips of the fingers, the handle is suitable. If there is too much space, the handle is too big. If the index finger does not fit, the handle is too small.
    2 method: extend your hand and measure from the center of your palm to the tip of your ring finger. Then the result obtained in centimeters should be compared with the size chart available below.
