We have an outstanding stock of brand-new racquets, so the previous version of demo racquets is no longer needed. This is an exciting opportunity to get a nice racquet for a nice price!
The demo racquets we will part with are all in good or very good condition and are strung. Many of them are strung with high-performing strings. The racquet you buy will be fitted with a new Head Prime Tour overgrip.
Please text us (407.491.4755) or email us (johngugel.tennisrocks@gmail.com) with your questions, inquire about what demo racquets are still available, or inquire about a specific racquet.
We need the space, so help us by helping yourself to a great racquet!

If you can not make it to the World Headquarters to pick up your racquet, shipping in the United States will be added.

Besides looking great, this racquet offers some welcome performance features:
The following table lists most of the features. One essential feature is the grommet system, a “cap” system that helps protect the string from court damage caused by “ball to foot” pickup! If you can’t stop doing that, you need this protection!
