I have a voltric zforce 4u and am contemplating on wether or not to get it strung higher. I really want to get it strung higher at 28lbs but I'm wondering if it will damage the racket in any way. I'm also wondering if I leave a racket in my bag strung at 28lbs will it damage the racquet due to not playing with it. (Racquets such as the mx70 3u, bs09 3u and zforce 4u) lol sorry if I'm a bit confusing
what string are you using? you can always try thinner string at lower tension which will give feel of thicker strings at higher tensions
oh, I see that you use bg80p and ngb99 from another thread... how many lbs?.... perhaps zm65 at the same tension or 1-2 lbs higher would be a good try... much better repulsion and feel
just do zm65 at same 26 lbs... second part question: high tension causes more problems with cracked rackets in clashes more than problems with storage
Shouldn't be a problem but 4U max recommended tension is 26lbs. So you void warranty if you exceed if you care about that sort of thing!
it is not a black and white, "has problem" or "no problem" as you increase the tension to something as high as 28lbs, it will increase the chance of racket breakage, whether from gradually weakening the frame structurally or from increasing chance of taco'ing the frame on a string breakage, and will potentially shorten the longevity of the racket. having said that, i have seen rackets being strung at 28/30lbs for years without any problem. the chance is yours to take
and what I'm saying is that it's safer to go to a thinner string at the same tension than to raise the tension beyond your warranty limit... just in case you need it...
As Kwun has said. There is a risk of racket breakage. It would be unusual for it to break during the stringing process but more likely a clash of rackets. However I have had different types of rackets strung @ 28lbs - 30lbs for years and have never had a problem. The z force is also a well constructed racket so should be able to handle 28lbs. If it was my racket I would go for it.
The Z-Force frame is very strong - I would have no reservations taking it into the low 30's. Rackets are at their safest when not played with!
