Let's get geeky!

Small business does not mean lesser quality!

Lack of tension stability & high string stiffness are often the 2 biggest disadvantages when considering playing a co-polyester string.

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. Here is a comparison to some of the most used strings in the industry.

(Stiffness: The higher the number the more stiff the string. Tension Loss: The lower the number the better the string held its tension!)
