Explanation
MIZUNO, a major sports equipment brand, is a latecomer in the table tennis world, but in order to differentiate it from other table tennis manufacturers, we have taken on the challenge of co-developing rubber with Sumitomo Riko in the table tennis world. The jointly developed rubber is the Q series. Shortly after the launch of the Q3, the Q4 was launched. It is a series of rubber that has been a hot topic since Q3, and the background is the fact that Mizuno jointly developed with Sumitomo Riko from scratch to develop a rubber for top players. It would have been very challenging and inspiring to the table tennis world!
Although katsuo000 is not familiar with table tennis rubber manufacturing, basically each table tennis manufacturer does not have a manufacturing factory, and specify the sheet material, sheet grain shape, sponge material, sponge hardness, etc. Most of them are outsourced to factories and manufacturers that can manufacture rubber. Therefore, it is not created from scratch, but the sheet material, grain shape, sponge material, and sponge hardness selected from the options. There will be many combinations, but the combinations required for trendy rubber will definitely be similar. Sumitomo Riko is a manufacturer that has not manufactured rubber until now, so it is clearly different from rubber made at other rubber factories.
The rubber that seems to have been used as a reference in the joint development with Sumitomo Riko is probably the Monster Rubber, Tenergy series. Currently, there are three types of Q series sold, Q3, Q4, and Q5, but the Q4 that is being reviewed on this page is the rubber with the highest rotational performance. It’s a rubber that corresponds to Tenergy 05 in the Tenergy series.
Various information is posted on Mizuno’s homepage, so I quoted it.
Q4 has a grain thickness of 1.7 mm, which is the same thickness as the grain thickness of Tenergy. The distance between the grains is 0.58 mm, which is the narrowest in the Q series, and the shape is dense. Tenergy 05 is a rubber with a grain thickness of 1.7 mm, the distance between grains is the narrowest, and it is characterized by ball holding and high rotation amount, and Q4 is a grain very similar to Tenergy 05. It can be said that it is a shape. Also, probably, the Tenergy series does not change the seat thickness / grain height, while the Q series changes the seat thickness / grain height for each Q rubber. As a result, I think that the images of the Tenergy series and the Q series are quite different when compared in the series. In a nutshell, while the Tenergy series feels a difference in published performance values, I feel that none of the rubbers are too sharp, but in the Q series, each rubber has a strong individuality and is the same series, I felt that Q3, Q4, and Q5 each had a strong presence. Regarding Q4, in Q4, the sheet is 0.8 mm thicker and the grain is 0.95 mm lower than other Q rubbers. I think that this sheet is hot because the sheet that is popular in German rubber has a sheet thickness and grain thickness that goes against the thin shape. If anything, the grain shape with thick sheets and thick grains is the shape found in adhesive rubber. I would like you to see the contents of the trial hit to see what kind of characteristics this grain shape gives to Q4.
Published performance value
Published performance values exist in the GF series, but in the Q series, only figures and matrices exist. I quoted it from Mizuno’s homepage.
You can see that the Q series has higher speed and rotation performance than the GF series.
You can see that Q4 has a high arc line like Tenergy 05 and it is difficult to get a long distance.
The above figure is a fairly scientific figure, which is interesting for me personally, but difficult to understand. The rubber material used for rubber has viscoelasticity, so it is a diagram that quantifies how it responds to external forces.
This figure seems to be the efficiency of the force that tries to return when the force is applied to the rubber. It seems that if it is hard, the energy loss will increase. Imagine that you probably make a graph like this for each rubber composition. I think we are deriving a rubber that is reasonably hard and properly energy efficient.
It’s easy to understand. It can be said that Q4 is a rubber that corresponds to 05 in Tenergy and Dignix. However, you can also see that they are not exactly the same. Probably, the Q series seems to have been developed in combination with Mizuno’s signature racket, Fortius FT or Fortius FT ver. D (Fortius FT ver. D), and it seems to be a rubber that goes well with wood-based rackets. The wood racket has a good ball holding and is easy to rotate, but the speed is a little slow and the arch line is high and it is easy to come out. I think that it is a rubber specification that compensates for the slow speed and high arc line.
Q4 pasting and weight
Continuing from Q3, Q4 also has a great amount of rubber warping. I think it’s under tension. It’s really amazing that it’s warped so far before it’s pasted. Like Q3, Q4 also has a unique rubber odor. Sweat.
Q4
Tension type (XL52/3)
Thick grain shape, narrowest between grains
・Sponge Thickness: middle (1.7 mm), thick (1.9 mm), extra thick (2.1 mm)
・Sponge stiffness: 47
・6,300 yen + tax
・66 (before cut) → 49 g (after cut)It’s less than 50 g. I felt it was lighter than I expected.
Three features of Q4
Don’t fly! The drive is shallow and easy to enter!
Q4 has a shallow drive! For this reason, Q4 may feel like a very straight trajectory for some people. Compared to Q3, Q4 felt rather soft, and the adhesive rubber-likeness was a little understated. It is easy to lift the ball against the swing and I do not feel the height of the arc line, but I felt that the speed was rather fast because the flight distance did not come out any more and I entered shallowly and the anti-aircraft time was short. I’ve tried many rubbers so far, but it’s the first time that I have a unique feature like other rubbers! Katsuo000 doesn’t know the rubber that feels the speed because the ball is shallow and straight even though the arc line goes up like Q4. It was a very unique rubber!
Push, stop stops and counter drive is easy!
As with the Q3, the Q4 also had a perfect stop and the overwriting counter drive was a good impression. I felt it in Q5, so it can be said that it is a feature of the Q series. I think the Q series is an ant just because of the features of this Tsuttsuki / Stop and counter drive!
Easy to handle even though it has a strong amount of rotation!
Compared to Q3, Q4 is obviously softer and easier to use, yet I was able to apply a strong rotation! However, when used in the fore, the hardness is a little unsatisfactory for me personally, and there may be a back rather. I think it is a rubber that can produce a ball like a soft adhesive tension / hard spin type tension.
Each technics review
Forehand
Light hit
I didn’t feel any discomfort. It smelled a little.
Drive on long balls and rallies
Like Q3, Q4 was about to lose its drive. If you try to play a thick ball, it will bite so well that you will feel it hit the board immediately, and the stiffness of the entire rubber may be a little weak. Some people may feel that the rubber loses this. When I drive it by biting it, I feel that it hits the board immediately, so it is easy to get a long distance with Zhang Jike ZLC, but I felt that it is easy to make a speed drive with a weak rotation amount. This is why I felt that Q4 was not suitable for the foreground.
Drive with open face
Although it is a hard rubber, I felt that it hit the racket board immediately. Like Q3, if you let Q4 bite too much, it will not rotate and it will be easy to make a mistake.
Loop (top spin) drive against back spin
Q3 was also a high quality loop drive, but Q4 was also a high quality loop drive as expected. However, I also felt that a harder sponge would result in a stronger loop drive.
Speed drive against back spin
As with the Q3, this also requires attention, and the speed drive at about half the speed and half the rotation became stable. However, Q4 is easy to rotate and soft, so I think it is relatively easy to do.
Curve / shoot drive
Like Q3, I didn’t hit it very carefully, but it felt pretty good. It was better to get involved a little and drive a little like a curve drive, because the rotation is stronger and the ball is stable because of the lateral rotation.
Block
This was as easy to do as Q3. I think this is because it is hard and not easily affected by the rotation of the other party.
Counter drive
I’m glad that the overwrite counter drive was easy to do as well as Q3. Also, I felt that the counter drive was easier to get speed than I expected and I didn’t intend to put it out, so it would be a drive that I could aim for no touch.
Stop
I’m glad it was easy to stop the ball. I think it is easier to stop than the hardness of the sponge.
Push
It was good that this was also low. I think that it will take rotation if you stick it well.
Serve
It was good to be able to cut it firmly. It took more rotation than Q3 and it felt very good.
Backhand
Light hit
I didn’t feel that hard.
Drive on long balls and rallies
It was surprisingly easy to do. I felt it was soft. I think that Q3 makes the sponge harder because the grains are easy to fall down, and Q4 makes the sponge softer because the grains are hard to fall down. There was a sense of stability, I drew an arch line and felt the speed, which was a very good impression.
Loop (top spin) drive against back spin
It was very stable because I could hold the ball firmly and rotate it. It’s soft, so it’s good that the impact is less likely to occur.
Speed drive against back spin
I think it will be easier to hit than Q3 if you practice.
Block
It was easy to do because it was hard and not affected by rotation very much.
Stop
It was easy to do. There was a net mistake because it stopped a little too much.
Push
It was good that this was also low. I think it will expire in Q4.
Chiquita
It’s really easy to do. You can go for a full turn.
