How are light version of racquets made?

[yogictennis]

are light versions of racquets made by putting less carbon fibre material all across the racquet, or are both light and normal versions the same amount of material, but the normal version has extra weights placed in different areas?
If they have different amounts of carbon fibre, will it not affect the flex ratings or how the racquet feels (besides the simple weight difference)
Is there a formula that says how much you should change string tension for differences in weight between versions?

Very good question but I think it is simply the later due to cost.

I'm surprised no one has answered this one yet.

I think it’s the same and that heavier ones have extra weights in them

supposes that it is the arrangement of fibers (direction of the fiber) which makes it possible to stiffen, and perhaps the addition of certain more rigid fibers, which make it possible to recover rigidity, by reducing the quantity of material and therefore of weight.

at the very beginning of the pro kennex pearl era, my father bought me one which did not last 1 month, it was very light compared to the prince graphtie pro, and it broke at the level of the round branches (like pure drive), and it was a braiding of fibers, totally different from what you can find "in" the head, rossignol or prince. or it was massive.

There is a third scenario that comes from the QC process where rackets that fall higher or lower than the targeted spec get relabeled as a heavier / lighter model of the same line or even be put into a totally different line.

This is a great question.
I don’t know the answer but I have often wondered because my understanding is that pro stock frames come in light allowing for customisation. Surely these must be top quality?

Yonex puts more weight with fibres at the head and throat as also little metal plates under the handle foam.
Putting the whole weight in the handle would make not a good racket. So I think most other brands do the same. You can see this in the TWU.
