​Why you want to try the sample package!

Our production team was able to develop a co-polyester compound that is superior in tension stability and string stiffness (arm-friendliness) to most co-polyester strings in the tennis industry. Those 2 characteristics build the foundation for a top-quality co-poly string.

​For Triumph, our high-end multifilament string (which is engineered with more than 2000 microfibres (16 gauge)), we spared no cost to develop a string that can compete with the highest quality in the industry.

Objective Test Results

All our strings have been lab tested by the United States Racquet Stringers Associations. The results speak for itself. Most of our strings show exceptional performance in tension stability and string stiffness. 

​T1-Firewire, Black Knight and Ghost Wire, for example, showed one of the highest string tension ratings for polys in the industry. Ghost Wire and Black Knight ​were ranked as one of the best polys in the "low string stiffness" category!
