    Arrow The "U", the "G" and the "tension" specifications of a Badminton racket

    .
    Greetings,

    This thread is for our new comers to Badminton Central.

    What does it mean?... The "U", the "G" and the "tension" specifications of a Badminton racket.

    Each brand of manufacturers make different series of rackets. Within each series manufactured, there are different models. And within each model manufactured, there are different specifications: weight, grip size and racket tension.

    Badminton racket specifications:
    The weight is denoted by "U"; the smaller the number, the heavier the weight.
    The grip size is denoted by "G"; the smaller the number, the larger the handle size.
    The racket tension is denoted by "x lb to y lb"; the minimum to the maximum stringing tension
    recommended.

    Perhaps in the future,
    we will get another specification to denote the stiffness of the racket shaft.

    Cheers... chris@ccc

    Yes, exactly. So many new-commers to BC tend to ask people what the U's and the G's stand for, before actually getting to use the 'search function'. I couldn't find the search function when I first joined this forum, but luckily some other person had already asked.. so I just read that and understood the meanings.

    Oh, you should also state that the racquet specifications can differ from brand to brand.. the one you've stated in this thread is the most commonly used specifications, the Yonex version. Some other brands such as Prince and Ashaway have opposite gradings, such as.. G2 = G4, etc.

    by the way, not all manufacturer standardize the weight and especially the grip size.
    in Yonex, G3 bigger than G4 bigger than G5. some manufacturers are in the other way round, G5 > G4 > G3. just be careful if you are order online and cant have the hand-on grip test.

    Could we list those brands that produce G5 > G4 > G3 > G2 > G1 ?

    Almost all racquets made in China and Taiwan. Not only are their numbers the opposite of Yonex, their wooden handle shape is more round which some people prefer. China makes more racquets, by at least a factor of 100 to 1 than the rest of the world.

    I think this is strictly a Yonex nomenclature, which is very general and rather limited. Yonex does not specify design balance points. However they do specify the weight categories of the U but not the specific dimensions of the grip G sizes, although Yonex does have details of the latter which are not made available to the public. The tension range on Yonex racquets is not a specification but a recommendation. Chinese manufacturers also specify different lengths for different types of players, different balance points, and different shaft stiffness for different types and *** of players.

    Ashaway and even perhaps Prince are just OEM brands made in China. There are perhaps thousands of OEM brands made in China, and they would all have a different handle specs from Yonex. I learned this the hard way when I gave the manufacturer Yonex specs to make a batch for me. Now I know better.


    We hope to be informative to our new members@Badminton Central.

    Good idea and highly commendable, but it would be better if you can qualify your title with Yonex specs only.

    Winex does the Grip sizes differently than Yonex with G1<G2<...<G5 with G1 being the smallest and G5 being the largest. Winex measured its grip size in one-eighth of an inch with G1 being 3 1/8; G2 = 3 1/4; G3 = 3 3/8 and G5 = 3 5/8.

    The weights are differentiated by U with 2U, 3U, 4U and 5U being the lightest. Prior to carbon being utilized by the racquet manufacturers, the weight were measured differently than using the U designation. In general, Winex designates its weight categories as follows: 2U = 90-95g; 3U = 85-89g; 4U = 81-84g; and 5U = 75-80g.

    I would add that racquet tension are measured by the mains followed by the cross so a specification of 22lbs x 24lbs meant that the mains are strung at 22lbs and the cross at 24lbs.

    here u go:
    http://www.badmintoncentral.com/foru...ad.php?t=54471

    dont know which grip size suits u? just go into the shop and pick up 2 rackets with G4 and G5 grips separately, and swing them about. give or take a little, depending on whether u plan to wrap an overgrip directly over the original or tear off the factory grip first. whichever feels more comfortable is the one u should go with.

    weight wise, u really have to look at your own playing style and strength

    good luck
