View Full Version : K90 and arm pain?

I am contemplating of trying the K90 since I liked the quick test of it last week, but I am concerned with a possible arm pain due to its stiffness. At the same time when I was hitting with it it felt both stiff and comfortable which is why I am a bit confused about it.
What is the word on its affect to the health of the arm (shoulder, elbow, and the wrist)?

Thanks

It does say its for the advanced player but if you can handle it then go for it :) in a 4.5-5.0 myself and have no problems with the k90...i love the frame

That is the thing! I am playing with Redondo Mid (which is somewhat similar to the K90) and my test impressions where excellent as well! It felt pretty natural to swing that frame and I like the ball that was being sent to the other end!
So, I don't think there is any issue about whether I could handle it or not!

i dont believe you should have arm pain with this racquet. the weight of the racquet helps absorb the impact of the ball despite its stiffness. get a demo of it and if you experience any pain then stay away.

When I first got the k90 initially i did have an arm pain but it was only because of the strings. I do have a very very sensitive elbow and this was one i had no problems with.

Stick with the k90 it wont hurt you itll only make you better.
The k90 has allowed me to focus more on my game. Im used to such heavy racquets and i have no problem so far for the 4 months ive been using it.

It is a good racquet but if you have a sensitive arm stay away from it. It blew out my elbow.

Yep dont go near the K90 if you have a sensitive arm...I used the N90 for a year without pain then switched to the K90 when it came out....it wrecked my arm and I had to wear an elbow support at 17yrs old which is not good...also didnt play well for a long time after that. IMO its not a comfortable frame and is like a PD for arm comfort.

If your a 4.0 on a regular day, probably more like a 3.5 then you should probably stay away from the K90 until you improve your game because this racquet is designed more for advanced level players. If the racquet is giving you arm pain due to the stiffness rating and weight then avoid this racquet at all costs. Thats crazy that you would stick with a racquet that is giving you arm pain, just say "no" and move on to a different racquet.

I thought this racket was horrible. Stiff as a board. Loved my 6.0 85's. I even had them leaded up. I highly doubt Fed's k90 model is as stiff as the retail version.

When I tried it it actually felt really solid and I didn't feel anything that would alarm me for my arm health! The racquet was stiff, but also flexible in a way. Kind of not sure about this, which is why I started this thread...

And, I am definitely not a 3.5! As I said on a regular day I am 4.0. On a good day I could beat 4.5 guys as well! :)

People is so different indeed. IMO, K90 is the closest to PS85. I don't feel is stiff at all.

OP: I don't have rating but I have no problem playing 5 set with 3 -4.5 .. I'm not sure about 5 and up though. At first start, everything was ok but my serve was bad because I used too much wrist after praticing for a while everything is ok ... and my game is more aggresive and more offensive than before ...

arm pain typically comes from poor technique >>>> not a particular frame.

I find the K90 to feel more flexy than either the nCode 90 or the PS Tour 90. The main reason for this is that both the nCode 90 and the PS Tour 90 contain HyperCarbon, which stiffens the frame, while the K90 does not.

I find the K90 to be one of the most demanding frames on the market. It is quite stiff and has a smaller sweet spot than any of the other 90 inch frames on the market. These factors make it tough on the arm. Hits which are not squarely in the center tend to be jarring, where as off center hits on the Prestige, Yonex Mids, and Volkl mids are not as stressfull on the arm.

Technique plays a role in whether or not you feel arm pain, but it isn't the only factor. Say you are playing someone who is better than you. They may play with more pace, spin, and consistency than you are accustomed to. The result is that, while your technique is sound, you may hit shots off balance or late, causing arm pain that you woudn't normally feel.

Only you and your arm can answer that question. Try it and listen to your body. If it hurts, stop.

Here's my anecdote. I developed a nasty case of golfers elbow while using probably the softest setup possible, a Redondo strung with iso-speed at mid tension. Yet, I can play all day long, pain free, with a k90 strung with either full poly or kevlar.

IMO...sometime it's depend how long is your play time also. If you play more than 3-4hours/day and play almost everyday, you might feel the sore or arm pain. b/c this racquet is kind of heavy.

It could be because your arm can't handle the weight of the racket, and is not yet adjusted to it. But since you did use the Rondendo Mid, I dont think thats it. Try using some softer strings. Natural gut. If you can't afford that on a regular basis, then Synthetic gut Pro Supex TItan might be the best one.

The Redondo is quite a bit lighter than the K90 at 12.06 compared to 12.5. The K90 is a strange racquet. So far I like it. But I have to string it pretty low (47 to 48) to find the best fit for me.

To the poster that thought it was boardy: what string tensions was it strung at?

Huh? What is Karophite? The k90 is 80% hypercarbon with a fancy name.

My current racquets are weight exactly 12.2, so going to the 12.5 didn't feel much (if any) different.

Well, I just used a stick from the guy I played match against for 5 min or so and I liked it. Now before I go an get one for my self I was asking to see how other feel about the affect to the arm from playing with it!

As I mentioned above, all of my Redondos are 12.2 (well one that has built grip has 12.4), so difference is minimal.

This is only my experience in the similar weight like 12.2-12.7, I get tired from too flexy frames faster than stiffer frame. I believe I want a lot of feedback from the frame and when I play with flexy frame such as Redondo Mid & Volkl Tour 10 VE mid I have tried to hit harder harder to get more feedback from the frame and sometime is too much.

There is no such thing as Karophite. There is such a thing as HyperCarbon - it's ultra high modulus graphite. Karophite is NOT HyperCarbon. If the K90 were 80% HyperCarbon, they would have to charge at least twice as much for the racquet as ultra high modulus graphite is very expensive. The K90 would also be stiffer than a soild steel I-beam with an RA > 100. HyperCarbon also requires double braiding which the K90 does not use. Compare that to the composition and the construction of the nCode 90 and the PS Tour 90. Do some research first!

Karophite is a brand name and is trade marked... that's it. There is no specific element that is/has a patent behind it.

Braided Graphite has a patent behind it... http://www.freepatentsonline.com/5683778.html

Additionally Hyper Carbon is also a real material http://www.popularmechanics.com/outdoors/sports/1283201.html
and is used in the Wilson Hyper Carbon (Hammer) frames.

Sorry Nick.

Karophite - it's just nCoded graphite: http://www.tennis-warehouse.com/ractechpage.html?PCODE=K61T90

K90 - No HyperCarbon: http://www.tennis-warehouse.com/descpageRCWILSON-K61T90.html

PS Tour 90 - Contains 10% HyperCarbon: http://web.archive.org/web/20030402000359/www.tennis-warehouse.com/descpageRCWILSON-WT90.html

Go look at a nCode 90 and a PS Tour 90. Both say "Double Braided" right on the beam. Go look at a K90 - nothing. HyperCarbon uses Double Braiding as there's one braid of regular graphite and one braid of HyperCarbon. It was also confirmed to me directly by Wilson that the K90 does NOT use Double Braiding, therefore, it contains no HyperCarbon. The PS 6.0 also does not use Double Braiding nor HyperCarbon, that's why many people think the K90 has a close feel to the PS 6.0.

Now here's a tip for you - Get your facts straight before falsely accusing someone of lying to avoid being publicly embarrassed and running away with your tail between your legs. :oops:

Prince NXG MP. Didn't really suffer problems as much as much less sore after playing. To me the K90 feels like a total natural fit. A third arm to match my third leg.

I have to be in pretty good shape to wield the K90 effectively. Honestly, if your not going to work out for tennis, stay away from it because you risk injury, and most likely won't see your best game.

He may be right - but there is no evidence of his claims. But he usually puts together a nice consistent story which could be correct.

I'd explain it to you but why bother? You're just here to troll anyway.

You don't even own any of the racquets in question so why do you even care? :confused: I don't really care if you believe HyperCarbon is real or not or if it's in the PS Tour 90 and nCode 90 but not the K90.
