Chung Racquet/String and Tension

Pro stock duel g like Tiafoe? Or something else under the paint?
Some people said special 16x19 drilling pattern earlier but now people are saying he skip top string to make 16x19.
Not sure which one is true.
Also it will be interesting that new vcore 16x19 will have same string density like Duel G (16x20) minus top string or new 16x19 pattern.

Chung should try/test Yonex Regna since he hits flat shots often. I want to see it might benefit him more or not.
I feel like it might be really good fit for Chung’s game because of characteristic of Regna.

With the way the things going on with Chung, he would change anything. He is the most patient and a smart one of all the nextgen!

Hello. I am Korean pro stringer.

hyun jung(hyeon chung) (-->In Korea, we pronounce it like this. 정현 ) uses a duel-g 310g racket and is not professional stock. just using extra lead tape 6 . 3 & 9 o'clock & 12 o'clock

Remove the cross first line of work and use 16 x 19.

Use Alu Power, averages 54~ 56 LBS and is uniquely 10 % p/s

And he got 6 rackets in Yonex, but he only uses 2.

during the game, So he keeps asking the referee to restring during the game.

329 grams unstrung! Can you comment about Swing weight or if that unstrung spec was with a stock grip, leather grip, or with an overgrip?

Thanks for sharing. Cool to have info about this on clearly a Rising star. Must be exciting to see him succeed!

Wow. That’s good information.
Now he can get pro stock and Yonex might be serious about him and making Chung’s own rackets.
310g stock is shocking.
I used to get Chung’s old Dunlop racket but sold it since he changed to Yonex.
Should get one duel G 310 for souvenir hahaha

The way I read his post it was 6grams at 12 6 grams at 3 and 9 and 6 grams at bridge so 18 grams on stock 310gr stick which is roughly 328-329 so that scale is not sensitive to 0.5 gram

Oh I see interesting. That should put him ball park 350, assuming like what 15" for 6 o clock? 20" for 3/9? Interesting they put lead at the bottom of the hoop too.

On second thought I read it as 6 12 3/9... There is weight at the bottom of the hoop too. Maybe he can clarify.

I saw the pic of 329g unstrung.
I was trying to point that he uses 310g stock racket instead of pro stock racket.
Well... it might prove that Yonex rackets might not need special pro stock rackets.
BTW Chung’s rackets might be void for warranty since his racket skip the top to make 16x19?? Hahahahaha

I don't think there's any value to pro stocks over retail other than just having less weight on them from the factory. 310 line from yonex has always been really light, which is great for modification. But that's just my take on it. I think yonex frames have been excellent for quite some time.

Yonex frame is not for everyone but Once one get used to...it’s excellent frames.
Still like my Regna hahaha.
Chung should try Regna. It could be perfect fit for him since he hits flat shot often.

BTW a little disappointed that Yonex only posted/promote Chung once in their Facebook.
Even Shapovalov and Tiafoe was there a few times but Chung’s news was only today’s news and they quoted “I just tried to copy Novak because he was my idol.” without congratulating winning 4R???
They are lucky to have Chung in this tournament since Wawrinka was out early.

Well I'm sure he will spark some heavy interest in Korea for Tennis. So I'm sure they'll be a bit more encouraging of his game soon! Korea is a massive market.
 

Phantasm

Semi-Pro
Good info on his specs already. Thank you @punkdog !

Never seen lead added to the bridge before on a pro's frame...He basically has even amounts of lead on all 4 corners of his racket head. I would think his racket is actually head heavy then with that much lead and nothing in the handle to offset.

Yonex just takes some retail frames and print his name on them I guess?

Honestly surprised that a fellow Korean is performing so well. I thought he'd be burnt out after playing a 5 setter with Zverev.

OK, let's break this down. How do you get 6 grams at 12 and at the bridge from that post. If you look at the close up pictures is 6g at 3&9, 1g at 12 and 1g at 6 (bridge). So total 8 grams to the hoop. No way he hits those weird straight arm forehands with that much weight in the head. Anyway...stock G97:

310g
+8g
=318g
+5g yonex OG
=323g
+different overgrip or some weight on the handle to make it 329g. The stock Yonex grips are really bad in my opinion and light. When I weighted them on a couple of my yonex frames they range from 11-13g. Replace that with let's say babolat syntec pro or soemthing similair and you get 18 grams, which is exactly the missing 6g of difference to 329g. Or maybe a lighter leather grip. Some thin leather grips can be under 20g installed on a L3 handle.

I think you guys are correct I re read his post and I think he is saying he has lead at 12 and 6 o’clock and 3 and nine so six was referring to location not grams. My bad

But that being said I believe he has 8-10 grams in the head and 8-10 counterbalanced in the handle somewhere...

Considering his rackets have his name printed in the throat, wouldn't we consider them "pro stocks"? These are not rackets straight off the local shop's shelf, so not retail. They should be considered pro stock, even though hes using the current line's racket and paintjob.

To me the lead tape looks like the wide version. That weighs 2 grams per 4 inch length.
It looks 2 grams each at 12 and 6, and maybe 6 grams each at 3 and 9. Overall at least 16 grams of lead.

That lead tape would add around 32 units to the swingweight. Possibly more, I'm conservative with my assessment of the lengths.

Even the 1/4" width lead tape I would say the same,

The 1/4 inch tape weighs half as much.
Can't be. Remember the beam width is 20mm, 1/2 inch = 13mm so can't fit that on the beam.

Yeah, something like that 6-8 on the handle somewhere.

Looks to me like (eye balling it)
6/12 = ~3g (8" / 4" * 1.5)
3/9 = ~6g (16" / 4" * 1.5)

310 + 9 (head) + 9 (handle) = ~328g

This racquet is magic to me with ~361g static weight with around 9-10g spread over 3/9, rest in handle.

I never tried this version but original version (orange) was really good after 5gr under the bumper. Never hit better kick serves

I agree Construction could be custom...his flex could be low 50’s for all we know.

Gotta remember now, all pros now, where not pros from the start.. sooo, their equipment follows suit..
he is starting to be recognizable, yonex will no doubt notise and custom his equipment;
im thinking that the new yonex coming out 2018, the vcore.dual.pro with the 16/19 pattern is his influence on this..
just my opinion..

Prestretched poly? :eek:
Yes, especially with Alu power which is very lively right off the machine. it makes sense to 10 % prestretch to take our some of the liveliness... Alu will probably go dead faster this way but I bet he strings frequently......

It's his legs. He gets down lower than any man I've seen and would make Kerber proud. His legs are from genetics. Koreans are descended from Mongolians (Genghis Khan) and skilled horseback riders. There's no amount of training that can get you legs like that.

Hi.
Wow! I was surprised at the huge comment. was 정현 so popular? (chung hyeun - In Korea, we call the last name first.)
Before I tell you anything you are curious about, let me ask you a favor.
Ah ... I am a typical Korean. I was born in Korea and raised in Korea for 44 years. I have never been abroad.( I went to a honeymoon abroad. hahaha.)
So my English is really terrible, so grammar and spelling are really terrible. That's a point! I would appreciate it if you would remember to read it. Okay? Then I'll get started.

Now ... Let me tell you about the tennis situation in Korea first. This explains how great he is.

Many friends are surprised that his racket is not pro-stock, but that is it. That's the reality of our country.
The nameseal?! (hyeon) of his racket now?! It was never there either. No, Yonex never cared.
hee got a name for winning the NEXT GEN . That's it. I'm serious!

No Korean professional athletes have PRO-STOCK.
Never. Each brand has 6 ~ 8 packs of rackets. It is not the same weight, balance, swing weight. Each player puts on a lead tape & grip and keeps the weight on their own.
Of course, the players do it themselves.

1. GRIP SIZE : The size of the sine grip is 1/4 size. His hands are very big. He is short on the air and looks small but he is not small. But do you know why use 1/4?

Believe it or not, it is very hard to get a 3/8 grip. 1/2 grip in our country. It is already a quarter used in elementary, middle and high schools, making it useless to pay 3/8.

2. USE GRIP : JUNG HYUN grip uses a leather grip. Ah, of course, he did it himself.

3. BUT HE IS LUCKY GUY : But he is very very very very lucky. You'll be really surprised to hear my explanation.

All the men in our country! YOUNG MAN have to go to the army. I went there, too.
When I went to the army, it was 26 months.
Now it's down to 24 months.

Korean youth can not go abroad well until they are 20. I think I'll run abroad without going to the army.

A written confirmation from one's parents to go abroad Like Terminator " I'll be back ", it is very hard for both my parents and my teachers to submit letters of confirmation, especially when I have to compete in foreign countries like an athlete.

But Jung hyun is totally chosen. Why?

Korean athletes have to go to the army without fail.
But athletes can be legally exempt. Stop exercising! Just do good.

On what grounds?
We need to either win medals in the Olympics, which takes place just every 4 years, or a gold medal in the Asian Games, which takes place every 4 years. (Sorry about the silver and bronze medals, but have to go to the army.)

Luckily, Jung-hyun took part in the Asian Games with "Im Yong-kyu" and won a gold medal, so he will be legally exempt so he can go abroad as easily as he is now.

So when an athlete goes to the army, everyone becomes an idiot and can't do anything.
This is so sad.

So Korean athletes run like crazy at the Olympics, Asian Games and Winter Olympics.
It's as if, " I'd rather die on the court than go to the army. "

See you in this winter Olympics. Especially young Korean men.

JUNG HYUN.. He's really lucky, isn't he?

4. REALLY NOT PRO STOCK ?! : And I wrote it on top of it, He got 6 RACQUET from Yonex, but his RACQET is swing weight and Balance are very different.
So he is only touring with 2 rackets.
If you watch the game tomorrow on TV, He is a quiet man and will say only one thing. after 7 game end. he always asks the chair umpire to "re-string please"

Fortunately enough, there is always a re-string at the string booth of the major competition.
But in small competitions, NOW STRING is often rejected, so jung hyun have to use the stretched string to finish.

This is his reality, and the reality of Korean tennis.

Please, my friends!

I would appreciate your support for 정현!!! JUNG HYUN! Hyeon Chung

Thanks !!

Excellent insight punkdog. Your english is really good too.

Hopefully as Jung-hyun gets more exposure in the tennis world this might have some impact on how freely korean athletes can travel abroad. It seems very unfair that they must win a gold medal or go to the army for 2 years before being allowed to leave.

You can’t say he is lucky to waive his military duty.
Actually He earned it with his gold medal in Asian game ^_^

Probably his racket situation will be changed after this tournament.
His coach might not like the idea of using two same rackets for tournaments.
His agent might talk to Yonex to give special rackets which will be exactly same specs.
Otherwise, He will leave Yonex for other companies after his current contract.
I only can find chung contracted with Yonex in Jan 2016 but there was no specific term. Only said multi year contract. Yonex should treat him better now hahaha
Also Chung should try Yonex Regna. I feel like it might help him more because of characteristics of the racket.

hee got a name for winning the NEXT GEN . That's it. I'm serious!

No Korean professional athletes have PRO-STOCK.
Never. Each brand has 6 ~ 8 packs of rackets. It is not the same weight, balance, swing weight. Each player puts on a lead tape & grip and keeps the weight on their own.
Of course, the players do it themselves.

1. GRIP SIZE : The size of the sine grip is 1/4 size. His hands are very big. He is short on the air and looks small but he is not small. But do you know why use 1/4?

Believe it or not, it is very hard to get a 3/8 grip. 1/2 grip in our country. It is already a quarter used in elementary, middle and high schools, making it useless to pay 3/8.

2. USE GRIP : JUNG HYUN grip uses a leather grip. Ah, of course, he did it himself.

3. BUT HE IS LUCKY GUY : But he is very very very very lucky. You'll be really surprised to hear my explanation.

All the men in our country! YOUNG MAN have to go to the army. I went there, too.
When I went to the army, it was 26 months.
Now it's down to 24 months.

Korean youth can not go abroad well until they are 20. I think I'll run abroad without going to the army.

A written confirmation from one's parents to go abroad Like Terminator " I'll be back ", it is very hard for both my parents and my teachers to submit letters of confirmation, especially when I have to compete in foreign countries like an athlete.

But Jung hyun is totally chosen. Why?

Korean athletes have to go to the army without fail.
But athletes can be legally exempt. Stop exercising! Just do good.

On what grounds?
We need to either win medals in the Olympics, which takes place just every 4 years, or a gold medal in the Asian Games, which takes place every 4 years. (Sorry about the silver and bronze medals, but have to go to the army.)

Luckily, Jung-hyun took part in the Asian Games with "Im Yong-kyu" and won a gold medal, so he will be legally exempt so he can go abroad as easily as he is now.

So when an athlete goes to the army, everyone becomes an idiot and can't do anything.
This is so sad.

So Korean athletes run like crazy at the Olympics, Asian Games and Winter Olympics.
It's as if, " I'd rather die on the court than go to the army. "

See you in this winter Olympics. Especially young Korean men.

JUNG HYUN.. He's really lucky, isn't he?

4. REALLY NOT PRO STOCK ?! : And I wrote it on top of it, He got 6 RACQUET from Yonex, but his RACQET is swing weight and Balance are very different.
So he is only touring with 2 rackets.
If you watch the game tomorrow on TV, He is a quiet man and will say only one thing. after 7 game end. he always asks the chair umpire to "re-string please"

Fortunately enough, there is always a re-string at the string booth of the major competition.
But in small competitions, NOW STRING is often rejected, so jung hyun have to use the stretched string to finish.

This is his reality, and the reality of Korean tennis.

Please, my friends!

I would appreciate your support for 정현!!! JUNG HYUN! Hyeon Chung

Thanks !!


PS : Don't COPY his PRE-STRETCH. It's just like his routine.
Thank you, very interesting. Imagine what is in North Korea then! Luck his game a lot and will support him. Do you know how he get Lacoste as a sponsor? do you compete in tennis yourself also?

I play nothing like Chung but use the same racket! I love it. It's strung with TB 19g mains and PL II 18g crosses and plays a dream. I'm thinking of leaving the top cross unstrung like Chung next time. Will it make any difference to the feel of the racket?

Hi.
Wow! I was surprised at the huge comment. was 정현 so popular? (chung hyeun - In Korea, we call the last name first.)
Before I tell you anything you are curious about, let me ask you a favor.
Ah ... I am a typical Korean. I was born in Korea and raised in Korea for 44 years. I have never been abroad.( I went to a honeymoon abroad. hahaha.)
So my English is really terrible, so grammar and spelling are really terrible. That's a point! I would appreciate it if you would remember to read it. Okay? Then I'll get started.

Now ... Let me tell you about the tennis situation in Korea first. This explains how great he is.

Wow, Korea and Yonex suck.
More like its Chung's team.

He doesn't have the right people in his team yet.

To make demands from Yonex, thats also Korean culture thing. They're very polite and crazy disciplined.

Look how long it took for Chung to get proper coach.

What???
I understand that he needs more team members but Neville Godwin made him awesome tennis player with 8 weeks.
There is a reason for 2017 coach of the year. Neville transformed his game like top 10 player. Amazing that it only took less than 8 weeks. Neville might knew chung needs to improve his serve and it might be working on progress.
It took 2-3 years to get ATP experienced coach but he did not have financial stability.
It’s gamble to hire ATP coach and having nothing after retirements if he is doing so-so player but he and his parents believed when he won Milan tournament and finally got Neville. Looks like Neville and Chung are clicking now. You never know if chung hired other coaches and have this much success. It turned out it was right time and at right place for chung.
