WHY TIER ONE SPORTS: TENNIS STRING INNOVATION: Over the past couple of years our production team was able to develop a co-polyester compound that is superior in tension stability and string stiffness to most poly strings in the tennis industry (based on lab test results from the United States Racquet Stringers Association). BEING THE UNDERDOG... The tennis business is a very competitive industry and Tier One Sports understands that it is competing against big global brands that spend millions of dollars in advertising and product marketing. Of course, we will loose the "advertising battle" but we don't mind. Through rigorous product testing, we believe in the quality of our products (and our customers seem to do as well...). In addition, we pride ourselves in offering a quick and friendly customer service as we are standing ready to give personalized tennis string advice. PRODUCT DISTRIBUTION: If you are interested in promoting/selling our products as a tennis coach, racquet technician, tennis store, tennis facility, online store, sales rep, wholesale distributor, please get in contact with us by dropping us a quick email at info@tieronesports.com
