Ghost Wire


"The smoothest poly I have ever played"

ONE OF THE SOFTEST CO-POLYESTER STRINGS ON THE MARKET (based on lab tests by the United States Racquet Stringers Association)! Ghost Wire is designed for players who seek the benefits of a co-polyester string but at the same time look for an elevated soft, arm-friendly playing response. Its new-generation polyester compound ensures players of all levels ultimate durability, high tension stability and precise directional and depth control. Its round, slick surface makes it a superb choice for hybrid string setups!

Please note: You can purchase this string in a  super thin 19 gauge (1.10 mm). Lab tests reveal that the 19g is as soft as many 16/17gauge nylon/multifilament strings on the market!

Who should try the string?

  • Players who would like to transition from a nylon/multi string to polyester.
  • Players who are looking for an arm-friendly playing alternative but still want to enjoy the benefits of a poly string.
  • All playing levels.
  • Ideal for hybrid string setups!

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.

Qualitative Lab Test Results Do Matter:

There are 2 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 very limited 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 their 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!
