Stringing Specifications For Your Demo Racquets

Tension

The majority of our demos are originally strung at 55 pounds, however, due to a shortage of inventory, we do have some variances in some of the models. We recommend confirming with a demo specialist before making any purchases.

If you have questions or need any assistance, don’t hesitate to contact us. You can reach our customer service center directly at (713)435-4816, or by email at demos@tennisexpress.com

Each brand promotes their own unique performance strings.
