I have been selling Victory Yoni Li Ningyu rackets for a long time. Let me give you a brief introduction. First of all, aluminum alloy from 46 yuan to 88 yuan, carbon-aluminum power series and HE series are egg-shaped racket. Secondly, 208 yuan to 240 yuan carbon fiber and carbon fiber plus resin Thunder series (duck egg-shaped racket frame) storm series (duck egg-shaped racket frame) flame series (rectangular box with big head) lightning series (small head) Remarks: duck egg-shaped racket frame has small sweet area, but small stress area and fast swing speed. Generous head racquet frame, large sweet area, easy to catch the ball, slow swing speed and large stress area. The small square head racquet frame is faster in attack and defense, and the swing speed and sweet zone are larger. Let me explain the sweet spot to you. The effective hitting area of the cross square with equidistant horizontal and vertical lines is called the sweet zone. Furthermore, the materials from 320 yuan to 840 yuan are all high-rigidity carbon fibers (except for the challenger TI70 from 800 yuan, which is ultra-high-rigidity carbon fiber), including the discontinued Discovery Challenger Explorer Super Wave ultra-nano power wave sword-shining pulse series. Finally, the most expensive 2008 yuan material in 800 yuan is ultra-high rigid carbon fiber+nano+titanium. 400 yuan thinks I can give you a brief introduction of several series of rackets and specific prices, as well as the futures price and spot price of the order: Challenger is an aggressive backcourt racket. Below 400 yuan, there are Challenger 9500 from 320 yuan, Challenger 9400 from 340 yuan and Challenger 9 100 from 380 yuan. The moderate hardness of the middle pole is 9500, hard 9400 and hard 9 100 respectively. Explorer series has both offensive and defensive functions, breaking wind effect and fast swing speed. Below 400 yuan are the explorers' old models 6100,6200, 320 yuan (discontinued) 6600, 380 yuan 6300 and 6400,6500, all of which are 420 yuan. The hardness of medium rod is 6 100 soft rod, 6200 medium rod, 6600 medium rod, 6300 soft rod, 6400 hard rod and 6500 medium rod respectively. Writing so much is the secret of victory, and I'm a little worried. ) Pulse 8800 and Pulse 8900 are sold in 420 yuan, with small square heads, both offensive and defensive, and the sweet area of the racket frame groove rises. The remaining Super Nano series, the cheapest ones are the prices of Super Nano 09 in 480 yuan and Super Nano 08 in 520 yuan, which are beyond your budget. The cheapest Chaolang series are Chaolang 3 150 and Chaolang 3250, both of which are sold in 560 yuan. For example, the cheapest dynamic waves 17 and 18 are also in 700 yuan. The cheapest Liang Jian series are Liang Jian 168 and 169, which are also sold in 880 yuan. As for the order, the spot price is 5.6 fold, and the futures price is 5.3 fold. Therefore, if you buy it online, you can first look at whether it is genuine from the price. Then I was looking at his racket. If I don't send it back, I'll see if there are any traces of pulling wires in the slot of the racket. However, I suggest you buy it in a physical store. Although I have been engaged in other industries, there are rules in this industry. If it is bought in a network, if it is fake, it will not stretch. If it is true, in addition to buying the thread, there will be an extra manual fee of 10, and the 20 yuan of each racket varies. I hope it can be for your reference. I can't sleep tonight, so I have a chance to enter your place. It is also the fate of you and me, hehe. All rackets can basically be pulled from the factory to 30 kg, but the service life is short. Then the electronic wire drawing machine is the so-called wire drawing scale, and now many places use mechanical wire drawing machines. The mechanical one is 2LB to 3LB less than the electronic one, indicating that there is eccentricity. So 25 or 26 kg is nothing, but you'd better ask the shopping guide to bring the racket to the machine empty, so that both the thread and the racket can be used for a long time.
