[Foreword]
With the introduction of the "technology abbreviation + digital model" this year, Li Ning has innovated the naming of its own racket models, golfers can finally better distinguish and remember Li Ning's three major technology platform products - wind blade series, energy series, and wind dynamic series. Li Ning racket has also taken a new level.

Some time ago, the editor noticed that Huang Yaqiong replaced a fresh and colorful new shoot with a fresh color and won the championships of various stations. Jia Yifan also won this racket in the Guangzhou finals. In order to their love, the editor couldn't wait to buy Miss Yaqiong's new battle 7000I, and brought its twin brother 7000B back. Next, I will appreciate the twin brothers and sisters carefully.
[Appreciation of Appearance]
It is said that knowing a person "starts with appearance", but in fact, the same is true for knowing a racket. If the 7000I and 7000B seen through the screen is just eye-catching, then after seeing the 7000I and 7000B, their painting and paint water can only be described as "stunning". The paint of my brother 7000B is based on a dark blue tone, and the black primer is also wrapped with emerald green stripes and a few tender pink patterns. It is relatively low-key and subtle from a distance, but also dazzling and dazzling when viewed from a close distance.
The sister's 7000I painted looks more attractive, with more colorful and beautiful colors. The middle and lower parts of the frame and the upper part of the rod are elegantly dark purple, and the upper part of the frame is conspicuous mint green. In addition, pink, white and emerald green are added to enrich the diversity of colors, giving people a visual sense of flowers that are gradually fascinating.
[Science and Technology Analysis]
Both Wind 7000I and 7000B belong to the Wind 7000I and 7000B belong to the Wind 7000I and They naturally also use Wind storing technology. The biggest feature of Wind storing technology is the design of a 4-hole air guide groove at the bottom of the racket frame, aiming to reduce wind resistance and increase swing speed. Choose the box-type frame with the strongest stability in the frame shape, so the blowing feeling of the Wind Dynamic Series is more stable and solid than the Wind Blade Series and the Energy Series, but the swing speed is slightly slower.
The technology used in 7000I and 7000B are basically the same. The "WING STABILIZER" on the frame represents a constant wing system, and cross-border application of aviation technology principles is conducive to the rapid recovery of the racket at the moment of deformation and inhibiting the shaking of the racket. "DYNAMIC-OPTIMUM FRAME" refers to mechanically optimized frames to make the force of swinging the beat more smoothly.
"STABILIZED TORSION ANGLE" on the middle tube refers to the reset elastic twist angle technology, which can effectively improve the torsional resistance of the racket. Even if the hits points offset, it can be quickly reset, improves the accuracy of hitting, and makes the offense more targeted. These are also standard technology for Li Ning's high-end photography.
[Practical parameters]
Model: Wind 7000B (W3) Wind 7000I (W1)
Weight: 87.3g (empty shot), 97.6g (including wire glue) 78.8g (empty shot), 89.1g (including wire glue)
Balance point: 298mm (empty shot) 322mm (empty shot)
Weight: 92.5kg/cm^2 (including wire glue) 90kg/cm^2 (including wire glue)
Hardness: Medium pipe—moderate, frame—more hard (the two are the same)
Configuration: Li Ning Line 1, two knots 28/26 pounds (the two are the same)
Although the technology they carry are basically the same, there are big differences in parameters. The weight of the 7000B is about 87g, and the weight of the 7000i is about 79g. The weight difference between the two is obvious. In terms of balance point, the balance point of the 7000i's air shot is as high as 322mm. You can feel the head of the shot when you hold it in your hand. Fortunately, the overall weight is very light, so the weight is not high. The balance point of the 7000B is about 298mm. When you hold it in your hand, you feel that the weight is evenly distributed and the overall feeling is strong.
The editor wrapped the same hand glue on both rackets. It felt like it was a little thinner when holding the 7000I in the hand. Later, after checking the information, I found out that the 7000I is an S1 (about G6) handle and the 7000B is an S2 (about G5) handle. The S1 thin handle is conducive to the force of the fingers and has a natural advantage when dealing with the ball in front of the net, which shows that the positioning of the 7000I is more inclined to the mid-front court.
Wear the 27-pound Li Ning line 1 for a warm-up trial. The overall 7000B is softer than the 7000I. When hitting a strong ball, the 7000B will not have any extra vibration feel, and the arms will not be sore and swollen after long-term use. Because the overall weight of the 7000I is light, it is not easy to use potential energy to deform the middle tube, so it will feel a little harder in the punching feeling, but in fact, the middle tubes of both are of the same hardness. In addition, their central tubes inherit the tough bullets inherited from Li Ning rackets, which are easier to produce a whip effect, and have a fast recovery rate after deformation.
Let’s talk about the lofty ball first. 7000B and 7000I pull up the lofty balls are easy to leverage, but their way of leveraging is different. 7000B uses the inertia brought by the high overall weight of the racket, and when swinging the racket, the forearm is more about exerting force. The 7000I relies more on the wrist to exert force due to the heavy head.
In terms of flat gears, the lighter overall 7000I is obviously better driven, and the pull-out speed is fast, which can quickly complete the coherence of the next beat; the 7000B is heavier overall, resulting in the speed of lifting and swinging the arm speed not as fast as 7000I. But both of them are straightforward and will not feel sticky, thanks to their excellent recovery speed.
It is worth noting that the 7000B handle is 10MM long, which is 210mm long. The 7000I is still a standard handle with a length of 200mm. When using the extended handle to pull the gear, your own grip is also moved up by 10mm, which is more conducive to quick swinging when pulling the gear and sealing the net.
In terms of killing balls, neither of them is the kind of fire stick that pursues a final decision, so the attack threshold is not high, and you can control it with a certain foundation of exerting force. The 7000I relies on the force of the bent fingers to kill. Although its balance point is high, the head and heavy feel are strong, the overall weight is very light. If you forcefully swing your arms and kill hard, you will feel that the ball is a bit floating, and the frame and the center tube are a bit disconnected. This is also the negative effect caused by excessive weight concentration on the frame. The 7000B's killing feeling is much more stable and solid. You can press down steadily without using your fingers to exert force. The swing is smooth and comfortable, and the killing performance in actual combat is also more stable.
[Summary]
The twin brothers and sisters of Fengdong 7000I and 7000B are very different, but the feel is very different. 7000I has a low hit weight and a high balance point. This parameter design is suitable for golfers with less strength, because it is light and easy to get started, and the obvious sense of head weight can fully utilize the force of head inertia when hitting the ball. The 7000B hit weight is moderate and the balance point is moderate; the swing feel is smooth and the hit feel is stable and solid, which can take into account both single and doubles.
