Official Product Reviews:

wow

35 year old open level tournament player. This string is a perfect fit for my game. Offers just the right amount of power and control. Excellent durability and it also keeps its tension until the string breaks. Will be ordering a reel."

Daniel

Advanced players string

"Fantastic string for the price with great bite. A very nice balance of control, power, and durability for advanced players. If you are not an advanced player look elsewhere."

Why Tier One Sports?

TENNIS STRING INNOVATION

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.

QUANTITATIVE LAB RESULTS DO MATTER:

There are two fundamental factors that build a foundation for the quality of a co-polyester string: tension stability and string stiffness. Having tested a great variety of strings from our competitors, we recognized the minimal number of strings on the market that perform well in both areas. Either the string is overly stiff or loses tension too quickly.

Bob Patterson from the USRSA (United States Racquet Stringers Association) provides readers with a comprehensive list of tennis string lab test results for string stiffness and tension stability. Bob was kind enough to test all Tier One Sports strings as well.

To offer some insight into the quality of our strings, we made sure to compare them to some of the "best," well-known strings in the industry!
