Help needed; Why racket had broken?

No stringer, so just guessing for fun, my theory is:

Spoiler

I think, that the string broked first, then the frame. The horizontal and vertical string will generate a symmetrically force pointing inward. Due to a broken string at the left side, the forces got asymmetrically and the frame broked at the weakest spot. One reason, many people cut the strings once a single string breaks, to avoid asymmetrically forces damaging the frame.

 

I almost stopped reading after the word "Lightfighter". Those things seem to break only by looking at them. I guess that the string snapped and then the frame collapsed. What caused the string to snap, that's might be another topic for discussion. I don't see the 4/4 rhythm on the mains being the main culprit for the breakage.

 

I don't know... at 12.5 kg? May be...??

However, I would rather guess that it was already a little cracked there from before... Do you have a habit of tapping the racket on the floor when loosing a point? . That is where it usually breaks when people do it...

 

I don't care about other options, all I'm saying is that the Lighfighters are extremely fragile frames due to the lack of material. And if you search through the forum just a bit, you'll find others who have made the same experience with Lightfighter rackets. So imo, you can stop spending more thoughts about the reason for the breakage - it's that bloody fragile frame that is to blame.

 

That's the second reason why I stay away from these light racquets, lack of ... durability !
And first reason : lack of EDIT heaviness in smashes. I only swear by good old heavy 3U racquets.

 

How is that being lazy? Don't you have to rotate the racket more often compared to doing them evenly? And I'd always give the string a little bit of time with the correct tension to lengthen a little bit. That's at least the few seconds it takes to pull the other string through the holes.

Anyway, my bet is on strings breaking first, too, otherwise the string would have snapped where the racket broke.

I used to play with LF rackets. Power is not a problem for me with lighter rackets, funnily my defense suffered due to the messed up timing. When three of them broke within three weeks (one of them a brand new replacement on the first stringjob), all at the same three spots without a clash or a mishit, I wasn't too sad about it. Interestingly, one of the three points where they broke was exactly the same like yours. So I blame the racket as well.

 

Yes the string Broke as a result of snapped String.

There are few more aspects.
1. How many times you have strung the racket.
2. What was the previous stringing tensions.
3. Where did the previous string snapped.
4. Is there any grommet issue.
5. & Many more aspects.

As you can see the racket is broken at the last string which holds the tension on the left side, Which clearly shows the racket broke because string snapped.

 

I guess the vertical string was moved (pulled with a string mover?) to help start the first bottom horizontal. It can be easy to over-stretch the string.
Or, if the grommet is old there could be a rough edge or split.
Or, a combination of both.

Do you have a picture of the bottom left grommets where the string probably snapped?

 

As you can see the broken strings are not equal in length. One string is about 15 cm shorter than another. Looks like it was not broken at the grommet but about 6-7 cm above it. For me it which indicates a mishit as the reason of breakage...

 

There is less string to the left to release tension compared to the right side. Plus some shared holes to retain tension.
I have suffered broken strings around the outer sides and the string always looks like that afterwards, despite the break initially being near or inside the grommet.

It does depend on the pattern, though.

 

I've had a Lightfighter break during stringing (haribito). Luckily the guy got a replacement from Victor. Since then I only string them using standard 2 piece, bottom-up pattern for added safety!
