6 Things Racquet Manufacturers Hide from Us

[@josephkulakowski3392]

One would think racquet companies cared more about us non-pro players. Who do they think pays their bills, pro’s sure don’t. The only company I have seen that cares anything about QC is Yonex. You are spot on with all of your comments.

[@allchannel1841]

so true, they're non chalant about the consumer cuz they know that just the minority understands all of this stuff! and the majority doesnt care or doesnt even know that this other characteristics exist lol

[@applesforakbar]

Indirectly pros absolutely pay their bills. Why do you think so many players played with babolats growing up? It 'the' goal for why companies sponsor big athletes, get eyes on your brand.

[@josephkulakowski3392]

Indirectly? Do the pro’s go to a shop and pay for their racquet’s, nope. The majority do not even play with the racquet they “endorse”. They play with pro stock which us non-pro’s cannot get. Racquet companies mis-lead the public. I beg to differ, without us racquet companies would go under.

[@tomr6955]

​@@applesforakbaryou're missing the point. The point is customers still have to buy their products..

[@rob.halpin]

It's kind of hard to figure out where the racquet are made. I had to do some serious digging to confirm that Yonex is the only company that doesn't make their racquets in a factory in China.

[@TennCom]

Yeah given show hard every manufacturer was hit by Covid, I think that there’s a very small amount of factories that all the OEMs share.

[@brandomaxwell]

First you go into the bowels of racquet tech with your recent video about Recoil Weight. Now you introduce us to Vibration Frequency? What kind of insanity is this?! The good kind. And I think you're onto something with your theory about Vibration Magnitude. Keep up the good work, Beckett.

[@TennCom]

I know it’s irresponsible

[@lucg378]

Just discovered your channel and I love your videos! Love how technical and in depth they are.

[@TennCom]

thanks Luc! Glad to have you and thanks for joining the membership!

[@returntotennis706]

Great content! I'd also like to see manufacturers put the manufacture year on the frame with the other specs.

[@TennCom]

year would be pretty cool to put right next to the grip size or something

[@rileywheb4444]

Not a physicist (just a mathematician) here, but I imagine the vibration magnitude would be very complicated to report. Even the vibration frequency is simplifying things a lot, because there are most likely many different frequencies present in the vibrations, each at a different magnitude.

[@TennCom]

Great points, to go even further, I imagine impact locations, direction, speed and spin would also be challenging to control for.

[@vanodne]

Love the nerd content, Beckett! Maybe now more detail on the numbers that we can adjust with lead tape and how they influence play (a la Racquet Tech).

[@TennCom]

quick maths??????

[@ProfessorStarJuice]

Awesome video Beckett!

[@nglfmark1]

Spot on. Well said educational and entertaining too.

[@doninocencio8153]

Manufactures will alway try to sell you their products. I'm a photographer as well, the camera doesn't make you a good photographer, it's your talent to understand how light behave. Same is with tennis, it's your talent and your abilities not the racket that makes you a better tennis player. Careful with the rackets you choose, I play with a lot of people whom carry every type of racket in their bag and they keep on switching it. Myself I have two, if one breaks, I take the other one. But them I'm not a profesional. The pros, I may bet is they have the same racket, with the same tension and the same string. Have fun playing is, my moto!

[@nihalnarisetty6656]

Hey Beckett, can you do a video comparing a few rackets? If you respond I will let you know which rackets I would want compared.

[@docstranger9520]

Very informative video thank you

[@TennCom]

thanks for watching!

[@christianolsson834]

Knowledge is power. Only the ignorant claims otherwise. I learn tons of good info here. And yes. We need feedback for our muscle memories to properly work. With Head racquets i get that sensation that makes the racquet ”predictable” but never harsh. With my prior overdamped racquets i got nothing. And hence i sprayed balls everywhere. Now i know at hit if the ball is going out or in at +/- 30 cm at the baseline. That is a predictable racquet.

[@DavidBazalar]

On the speculated vibration magnitude variable. If you want to follow the earthquake analogy thoroughly, the proper name would be vibration intensity. To put it in layman terms, the key parameter is the coupled characteristic frequency of the racquet connected with the player and the vibration (set of amplitudes/frequencies) generated when hitting the ball (there should be a classification of different type of solicitations depending on your and your opponent play style, your racquet setup, and your forearm length perhaps). If this external frequency set overlaps with the coupled characteristic frequency of the racquet and the player: You should have resonance, which is an out-of-control jerkiness, which will be felt as extreme vibration intensity. The big question is: Is that possible? You will need to ball-park these inner and outer frequency variables to find if resonance is actually feasible. If not (and this is probably the case), then the stiffness variable is enough.

[@thomaskuhn6541]

Great video. I’m a complete nerd, I always buy my racquets unstrung so I can check if they are to spec and return them if they are off. You just increased my nerd quotient - thank you.

[@TennCom]

hahaha thats a savage move. Well done!

[@maxgreene8285]

Hey Beckett, nice video very informative. I was looking for some information on strings. I bought and strung a brand new racquet and been using it a few hours. I noticed a weird buzzing sound on impact of the stringbed, balls and even when bumping my palm on it. Almost like a harmonic frequency. But after hitting a couple more hours with it, the sound disappeared. I'm probably being paranoid, also because I framed quite a few shots and was wondering if that had anything to do with it? I'd appreciate any input/thoughts you may have on this. Thanks ☺️

[@TennCom]

open the trap door in the buttcap and see if anything falls out

[@sebastiandomagala9233]

THIS is the very compendium about racquet specs. Usually I give a sh..., test a racquet and feel the difference. I recently bought my very first racquet without testing it and it proved to work quite well. The more you know, the more you can select prior to testing (or even buy without). Very useful video.

[@tafder]

Would be cool if manufacturers reported what their "acceptable" tolerances for static and swing weight are.

[@TennCom]

I think Babolat is the only one that clearly states +/-7g for static weight. They get credit for being clear, but that’s such a crazy range that all credit is lost.

[@tafder]

@@TennCom imagine if you buy 2 sticks, get really unlucky, and they differ by 14g static near 12 o'clock. Recovering that with customisation will be a bit of a challenge. I guess that's why prostocks are so light out of the line. There's a company in the UK called Angell sports that do "their own frames". Reading about their process, it sounds to me like they get light frames from china, then finish it in house to keep QC at a high standard.

[@eric4458]

@@TennCom Just like Tecnifibre T-Fight 2020 : weight +/-7gr ; balance +/-7mm

[@TennCom]

@@tafder oh wow I didn’t know Angell was that artisanal. Very cool

[@allchannel1841]

@@TennCom so you can have two same molds with 14 gr of difference lol

[@allchannel1841]

If they can atleast afford us the right weight and swingweight mentioned theorically, that would be a revolution !

[@TennCom]

that would be amazing

[@Sir_Leelord]

i wonder what the twist weight on a 2015 blade 98 18x20 is

[@TennCom]

"Wrong pole". lol

[@chrisb8698]

Oof, just watched this after buying the shift... 😬😬

[@nicolasX2602]

Is Shift any good? My first racket was a clash but as I get better I saw that flex does not help me at all

[@TennCom]

I hope you like it, for all of our sakes.

[@vscope]

@tenncom Well done! good summary, one thing i would like to mention. in my opinion, twistweight is also responsible for a muted feel in a racquet. i did an experiment, i took 2 racquets, same model with same specs but 1 tuned with twistweight at 13.5 and the other at 14.5 tw. guess what, the one with less tw felt less muted since the lower tw gives you more feedback. so maybe the old vintage racquets didnt have more feel, but they only had less tw :)

[@TennCom]

This is a very hot take but I agree. More TW means less vibration off centre means less feel

[@vscope]

@@TennCom you should try it by yourself. its really interesting how much the racquet changes its charecteristics if you change tw only. even a pure strike can become an agile racquet it you remove the red headguard and then customize it to your lower tw / sw likings :)

[@allchannel1841]

@@vscope but more tw means more plowthrough means more flex means more feel, so it's depends on what feel you talking about!

[@mypandabear50344]

Always get a depolarized racquet and work it with lead tape to your playing style.

[@danilozucchini6292]

Good video. I have a question for you. I'm 64 and the racket i use is a Head Instinct Liquidmetal Tour XL strung at 23kg with Tecnifibre NRG2, weight 325gr RA63 swingweight 336 100in and 16x19 of stringbed. I play more doubles today than singles . I wish an allround and powerful racket .I tryed Pro Kennex Q5 X PRO comfortable but not more powerful with the same string. What racket you reccomand to me between EZONE 100 , VCORE 100 and HEAD SPEED MP?

[@TennCom]

Between those 3 I like the EZONE 100 the best. Its very predictable for a power racquet so its easy to find confidence in control to complement the great power and stability.

[@andrewhwang8951]

Thanks!

[@TennCom]

Thanks so much Andrew!

[@K4R3N]

Nerd Alert! 🤓 This is awesome content. I hit with 360+ Speed Pros. I know their static and swing weights and balance point. How could I dig up more data on this stick?

[@aquadan3592]

Although I 100 percent believe this I think we should put it to the test. I use Head speed Mp series and always wondered if 2018,2020,2022 versions are actually different. It would be nice to black them out and see

I suggest that I am an idiot and you are correct

[@christiancherry1377]

@TennCom But loved the earthquake analogy!

[@bentozer2464]

The new version of this racquet will have improved power, stability, spin, comfort and control. Oh great, that's everything I'm looking for to improve my game.

[@TennCom]

it also costs over $300 now

[@ryansolomon4178]

Hey, since I am in Winnipeg as well, do you have an Ezone 98 2022 you want to sell. I’m looking for a 2nd one.

[@TennCom]

I don’t sadly

[@vijaynarsapur147]

fabulous and relevant video.

[@TheXlebushek]

But as I know we still don’t have a place where we can check all this values. TW trying to do some job but not for all racquets, especially HEAD 2022-2023, from 275 to 285 grams For example Extreme Team / Speed series, Clash 100L v2 or ULTRA 100L v4.

[@TennCom]

We are lucky that TW even bothers to track this stuff. I don’t think there are any other institutions that have the capacity

[@TheXlebushek]

@@TennCom I believe that racquet manufacturers have capacity but it’s smth like internal information. In any case I think that most of people will ignore this parameters because they can’t find any info about it and as usual will pay attention to sw / weight/balance

[@glademaster]

How is it that people consider Blade 98 as a stable racquet when the twist weight is a low 13?

[@TennCom]

Idk but probably 45 degree weave. Jk, but only kind of, probably has very little torsional flex

[@Sayat355]

My blade team v8 feels so disconnected 🤦‍♂️ and I was thinking of getting the ezone 98 💀

[@TennCom]

Imo Head currently makes the most connected feeling racquets.

[@kikibeldandy]

Agree head is much better in feel.

[@wilsoch]

The ezone will feel much less connected than the Blade. Some Head rackets are good, but not all. Pro Staff / Prestige are the most connected IMO.

[@mohammedfarag5845]

Great and advanced knowledge

[@jwc865]

Would love to see you review of furi arma pro 98 & 101… but mostly the 98

[@TennCom]

Tbh it probably won't happen unless they reach out to us for something

[@starfusionmz]

Median area of a cross square in the sweet spot would be a good metric for spin potential

[@TennCom]

yes this would be crazy to get. Currently we all have to rely on Time410s' analysis for actual pattern density.

I had the same feeling with the clash 98 but then I put solinco confidential and it was nice 🤙

[@KiboTennis]

Yes. The Ezone 98 has perfect specs for me, but I just can’t connect with it.

[@telquel7843]

On paper the ezone 98 is perfect for me. But having played with some friends Yonex racquets, it seems that muted feel is part of the brand. I love the quality of the racquets, but they feel so different, and I do feel disconnected. For reference, I use a Pure Drive Cortex 2006 weighted up to ~340g (mostly in handle but some in throat and 10/2 as well). 🙃 I keep telling myself I need to modernize the racquet I play with but so far haven't quite found the right weapon (no way the issues in my game are my fault, it's the racquet!). Would definitely love a bit better maneuverability for doubles but man that thing is great for service return.

[@Jakub_G_Tennis]

I love the feeling of the new ezone 98 so it may be subjective which is worth mentioning
