What is the difference between 3U and 4U badminton rackets? Many badminton enthusiasts have had such questions, and even some old golf course drivers who have been playing for a few years have a hard time explaining the detailed difference between 3U and 4U badminton rackets. The U in 3U and 4U badminton rackets represents the weight of the racket, but what is the difference between 3U and 4U badminton rackets? How big is the difference between the two? How should we choose 3U and 4U badminton rackets? The following Chutian Sports Channel editor will give you a detailed answer to the difference between 3U and 4U badminton rackets:
The U in the 3U and 4U badminton rackets represents the weight of the badminton racket. Looking back on the development of badminton rackets, after the advent of carbon badminton rackets, after several young and quantitative trends, badminton rackets finally broke through the empty racket weight of 100 grams. To commemorate this historic progress, badminton racket manufacturers use 100 grams as a base, and use values that deviate from 100 grams to represent the weight of carbon rackets. And this unit of deviation from 100 grams is U, and the U number refers to the weight of the badminton racket.
The weight of badminton rackets is diverse. Each racket is clearly marked with its weight. Generally, the weight of badminton rackets is divided into five levels: 1U\2U\3U\4U\5U. Like the handle size unit, different manufacturers have their own definition of the weight unit, but the popular one is the U system used by YONEX. Weight range: 1U: 95-100g, 2U: 90-94g, 3U: 85-89g, 4U: 80-84g, 5U: 75-79g, so according to the U system standard, the 3U badminton racket is about 5g heavier than the 4U badminton racket .
The weight of aluminum frame badminton rackets is generally more than 1U (95-99 grams), and there are also a few full carbon badminton rackets with a weight as low as about 80 grams called ultra-light rackets, which are mainly designed for women or golfers with special needs. And more than 95 grams are generally metal rackets, mainly for people who use badminton as a means of fitness and do not want to spend too much on equipment. The weight range of badminton rackets generally sold on the market is basically between 2U-4U.
The difference between 3U and 4U badminton rackets is simply the difference in weight. Under the same balance, the weight difference between 3U and 4U lies in the carbon yarn content of the head frame. Both the two rackets in the same balance, the 3U badminton racket has more yarn content than 4U. a few grams. The weight bar in the wooden handle is used to adjust the weight and balance. If the head is heavy, a carbon rod should be added to the wooden handle. If the head is too light, glue should be added to the racket frame.
Since it is said that the difference between 3U and 4U badminton rackets is the weight, some people may ask to choose the light-weight 4U badminton racket. In fact, the badminton racket is not as light as possible. The lighter the badminton racket, although the swing speed is fast, it will feel useless when spiking, which will affect the power of hitting the ball. On the contrary, badminton players with relatively low strength choose a racket that is too heavy. Not only will they not be able to achieve the desired speed when swinging, but they will be particularly tiring when playing.
Same as above, that is, how should we choose between 3U and 4U badminton rackets? When badminton lovers choose a badminton racket, the key is to choose according to their own power. The heavier racket (3U) is suitable for players who are strong and tend to attack, and the lighter racket (4U) is more suitable for players who tend to be more defensive. The heavier the badminton racket, the greater the inertial force, the lighter the badminton racket, and the more flexible it is to use. Therefore, if your wrist strength is strong enough, you can choose a 3U badminton racket with a heavy weight; if you are a girl or have weak wrist strength, it is recommended to use a 4U badminton racket.
