Individuality & Durability.

The ISOSPEED Hybrid System now makes it even easier for tournament and professional players: We have now optimized our ability to accommodate the needs of each and every player by offering four types of hybrid strings to choose from, each of which has its own different features. You can combine the mains and the crosses however you like - the result is a highly individual, tailor-made string bed.


Play your individual style.

The string properties may be combined in any way you like by varying the string on the mains and the crosses. The string must be set individually, depending on the type of player and the demands on the racket. The basic rule of thumb is: a stable main string should be used in kombination with an elastic cross string.


Make sure that fun lasts longer.

Moreover, a great advantage of the Hybrid System is that it considerably increases the durability of the string. While the mains often break on traditionally strung rackets because their movements are stronger and they rub against the cross strings, hybrid stringing makes it possible to combine a more stable and, therefore, longer-lasting main string with an elastic cross string. This results in substantially less racket deformation and, at the same time, a longer service life for the string bed tension.
