What Is The Meaning G3,g4,g5 And 2u,3u,4u On The Racket?

stiff head is when the head is stiff and flex..head flex

 

I've never heard of a stif or flexi head, normally these terms are used in relation to the shaft to let you know wether your racket is more for defensive or offensive use.

 

Hey Alcuard,

Please read up on the stickies in the appropriate forum before you post. The #U is weight classification for Yonex racquets and adopted by some of the other major brands as well. Also, it would do well for you to search the forums for answers as your questions most likely have been discussed many times over in the past. Answers for your particular questions can be found in the Equipment forum, please search over there.

 

Not true for Yonex. Yonex has indicated that the flex stiffness of their racquets is a flex measure of both the frame and the shaft, with an emphasis ".. please take note of that.."
Other manufacturers may use different definitions. SOTX uses shaft rigidity, which is self-explanatory, to describe the flex of their racquets.

 

Does that mean the entire frome as a whole (head + shaft) or for each constituant?

I don't quite understand

 

(for examples sake)

Yonex hold the racket on the desk with the only the handle on the desk, and the head and shaft hanging off. Yonex scientists hang the weight on the end of the racket (to the edge of the head.)

SOTX scientists however hold the racket the same way, but hang the weight at the junction between the head and shaft.


(or at least that is how I interpret it, but am sure they are much more scientific about it.)

 

No, I'm sure it is. That's how I was thinking as well but in the last two years Yonex catalogues I have only ever read, shaft: extra stiff etc.

So I'm almost certain that Yonex woud use this method as you describe above but am not certain what relevance including the head has in their tests since they are generally made of different materials and have material inserts etc.

I was looking for clarification what the "shaft and frame" meant also as I understand it the shaft and head together make the frame.

 

You are right that the frame comprises the head (which is often referred to as the frame) and the shaft, that is technically speaking for tennis racquets. But Yonex is quite clear in their email reply to my enquiry on Yonex's definition of flex stiffness. And Yonex in Japan says that their flex stiffness measures both the shaft and the frame (meaning the head in tennis tech speak) to determine flex stiffness. That is why the AT700, although appearing to have a less stiff shaft than the MP33, is rated as having an extra stiff flex whilst the MP33's flex is only stiff. The longer shaft of the AT700 has more bend and gives a feeling of a less stiff flex than the MP33, but Yonex says this not so because the AT700 has stiffer materials in the shaft and frame (head) that the MP33 does not have.
From what Yonex says you really cannot judge their racquet flex stiffness by merely bending at the shaft. Maybe, twisting it with one hand at the top of the frame and the other hand on the handle will give you a better idea.

PKMartin,

Those are grip size (G#) and weight (#U) classifications for Yonex racquets. Please refer to FAQs and search for answers in the forum before you post.

 

You got to be kidding me, this is the second time this questions been asked this week.

 

Welcome pkmartin!

different manufacturers have different meaning for the codes... they refer to the weight and grip size.. Yonex has them in reverse order.. 2U heavier then 3U and G3 larger than G4... but other manufacturers may have it the other way around... .do a search...
