New to Tier One Sports? You have been missing out!

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

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