You need to see this!
For years, we have been exploring the properties of materials that make up many of the tennis strings used by players now.
What we found, over fifteen (15) years ago, was that polyetherether ketone (PEEK) is the best string material for preventing arm, elbow, shoulder, and other injuries while enhancing performance.
What!
We love natural gut and use a lot of it; however, PEEK can take more “abuse” than natural gut, environmentally.
If you are joining the Racquet Quest community, you may be perplexed by this statement. And for good reason. If you are not near the world headquarters of Racquet Quest, LLC, you may have never heard of PEEK, marketed by Ashaway as MonoGut ZX and ZX Pro.
Why?
PEEK is a unique fiber that requires an understanding of its properties, unlike most other materials that do not possess the performance properties of PEEK.
Stringing with PEEK requires caring about the player and the racquet!

Ask your racquet technician to set up your racquet with this string. We believe you will be glad you did.
Save the Plastic (grommet)
If you have a tennis racquet, it probably has a grommet set!
A grommet set consists of several pieces of molded plastic designed to fit a specific racquet… a particular racquet. But why?
The materials used in modern tennis racquets are very strong and can be very sharp where the holes are drilled into the frame, so the swing can be installed. Without the plastic protection, the string could slice through the fiber or the fiber could slice through the string, and neither one is good!
Here is an example of extreme grommet wear.
