New racket missing top cross string?

Some stringer seems know some trick or string pattern that are uncommon.

Many times i saw a racket with string that skip the 2nd cross on top, bottom, or both. Not sure what gained from those pattern or would it break yhe

 

Yes, that racket misses the topmost cross string. Correct stringing pattern see (https://www.yonex.com/media/wysiwyg/YNEX0007_02.jpg). This doesn't endanger the frame in any way though, it basically just increases the risk of snapping the string with a mishit towards the top of the frame.

However, there always is one downside with Yonex rackets under warranty that are strung just slightly outside from their recommended patterns: They will plain and simple decline warranty in case there is an issue with the frame. So I would send this picture along with the recommended pattern to the shop and ask for a partial refund to cover having it re-strung locally. This is an obvious mistake by the shop's stringer so I can hardly imagine that they will decline that.

"It's not a bug, it's a feature!". No... sometimes a mistake is just a mistake and nothing else.

 

Im not sure if its a mistake as i often saw it. At 1st i tought someone string are snaping but he didnt realize it but looking at it closer, actually its not. & As i saw some people had it, makes me wonder what use skipping 2nd cross at the bottom or the upper or both up & bot.
Tho never in my life i end up with those string pattern & didnt bother to ask my stringger to do that afraid it would harm my racket.
But still im curious why is it & what its benefit.

 

You mean the third one is missing and that's the TTY signature pattern. It doesn't have any effect, except in someone's brain who wants to believe that it does. Don't let yourself be fooled by that kind of mumbo jumbo without seeing any kind of facts to prove it.

 

Sounds reasonable. I'd still try to get that partial refund though...

 

Oh I hate that pattern. It is so ugly. You can only add the last cross if you have a 4 tooth clamp. So its possible the stringer had to omit it because he did have the more common 5 tooth clamp.

 

I can understand why some stringers does that, on a basic or intermediate 72 holes racket, the most common stringing pattern is last string at hole 7 and tie off at 5.

This astrox 99 pro is slightly different, last string at hole 6 and tie off at 5. All racket is slightly different, a more experienced stringer would pay attention to new emerging patterns. Saying that, I made a similar mistake in the past but on my own racket as an amateur DIY stringer . Shop should not make this mistake.

 

Its fine imo.
Yonex Astrox 99 Pro is a 68 grommet racquet with a really tall last cross string. Not many stringing machine has a low profile top clamp so the shop where you ordered probably chose to omit it due to the top clamp interfering with the last cross string.

Example here with similar 88s Pro

It's not common to see stringers use different patterns, knots and tie point. Even amongst Yonex credited stringers across the tournament circuit.

For the mentioned 5 teeth clamp issues above. It can be easily solved by doing the last cross then back to second last and tension it twice then tie off. This will result in the last cross being a bit less tension but a lot of Yonex stringers advocate perimeter strings to be slightly less. Otherwise two flying clamp will do the job too.

Yonex asia, finish knot of the cross string at the share hole on the 11th vertical string grommet to take pressure off the 5th vertical string where often snapped string occurs. The procedure as follows- a stringer reach the cross at the 11th vertical shared hole. They then work from the last cross down to the 11th grommet to finish knot.

I have since adopted this method and seems to have lower the chance of the vertical string snapping where the knot is typical situated on the vertical.

As seen on youtube video European stringers are adopting the Yonex asia method i explained above.

plane.

 

Thank you for sharing this video.

Interesting starting knot for the crosses too. I will try reversing the top 5 strings next time.

 

It seems the stringer strung the mains at 32. The last two mains at 35. He then strung the crosses at 35. And the cross before the tie-off at 37.
The Yonex 2-string pattern recommends dropping the tension on the last 5 crosses by 10%. So in the above example, would it be recommended to string them at 32 lbs (and the cross tie-off at 35)?

Thanks for pointing out the reversing of the last 5 crosses in the video. I had missed it when I first saw it (or forgot about it). I'll try it out and compare results on identical racquets strung with the same string on the same day.

 

Yes. Last 5 Crosses would be 32lbs and the knot 35.

 

If you can’t ship it back, getting it restrung locally sounds like a good plan. Just make sure the stringer knows about the clash and checks for any other potential damage before restringing. If you’re worried about the frame, maybe take it to a pro who can do a thorough check.

 

Sorry, but "only" is wrong.
As a stringer get yourself a flying clamp for these special cases and you're fine.

And most important, in the end the customer shouldn't be the one who has to take the consequences. If you as a stringer cannot string the racket properly then get the right/needed tools or stop it, but don't deliver bad quality.

 

Crosses are at 34 lbs because Axelsen wrote it on the stringing sheet (see beginning of the video).

 

That explains some of it. Since Axelsen asked for 34 lbs crosses, the stringer tensioned all the crosses at 34 except the last one at 37. Yonex recommends dropping 10% for the last 5 crosses to supposedly "maintain the racquet shape" and have a larger sweet spot. I suppose professionals don't care much for either.
