Differences between carbon and fiberglass

Before talking about the different types of carbon fiber in padel, it is necessary to answer some questions. One of the most frequent concerns the difference with fiberglass, as players always wonder which is better or which they should choose. The main difference between carbon and fiberglass is hardness. Carbon fiber tends to be firmer and stiffer, while fiberglass has a more elastic composition. This affects the feel and playability. A racket with fiberglass faces gives a softer and more bouncy feel to the ball, compared to a carbon racket which is distinguished by its solidity that promotes aggressiveness. However, neither is better than the other, although, in general, carbon is more durable than fiberglass. They are simply recommended for a specific level of play. In general, professional rackets are made of carbon, while beginner rackets are made of fiberglass.

Differences between 3K, 12K, 18K, and 24K fibers

If you've spent time looking for padel rackets, you've probably noticed that there are different types of carbon fibers. In general, they are cataloged with a number and a letter, which can be 3K, 12K, 18K, and 24K. This nomenclature refers to the thickness of the fiber, which is determined by the quantity of threads that compose it. For example, a 3K fiber has 3000 threads, while a 24K fiber has 24000. Therefore, the latter will be a thicker fiber. This difference in thickness makes the ball striking behavior different. In most brands, this differentiation also refers to the hardness of the racket. That's why, the 24K carbon fiber would be the hardest, while the 3K fiber would be the least hard. However, there are brands that use this classification in a different way, one of them is Siux.

Siux carbon fibers

The Spanish brand Siux stands out from other brands by the classification of its carbon fibers. Like other brands, it also has 3K, 12K, 18K, and 24K fibers, but for them, it means the opposite. That is to say, for Siux, 3K carbon fiber is the hardest of all, while 24K fiber is the softest and most elastic. That's why, if you are considering buying a Siux racket, you should take this detail into account. If you are looking for a comfortable racket with a lot of bounce for the ball, you should definitely choose a 24K carbon fiber racket.
