Excellent playing characteristics with maximum arm friendliness

The Isospeed Professional Classic unites the playing feeling of natural gut with synthetic strings.

The objective of the Austrian manufacturer Isospeed was to unite the advantages of natural gut and synthetic strings. They have achieved this impressively. Over many years the Professional Classic has won many supporters in club and tournament events. The recipe for the especially arm-friendly string lies in the free swinging polypropylene fibres at the heart of the string and the welded polypropylene coating. This combination guarantees stable playing characteristics in all phases of the match. Thanks to the factory pre stretching the string retains stable string tension and durability.
