Before you come in.

A few things players ask us most often. Still have a question? Send us a message above and we'll answer quickly.

How long does restringing take?

Standard turnaround is 24 to 48 hours. Same-day service is available depending on our current queue. Call ahead or come in and ask.

Do I need to bring my own string?

Nope. We stock over 100 strings: polyester, natural gut, multifilament, and hybrid options. We'll help you choose if you're not sure what you need.

How does the demo program work?

Sign up for our 1-month demo membership to take out 2 to 3 racquets. Hit with them on court. If you decide to buy one, the demo fee is credited toward the purchase. No pressure.

What tension should I use?

It depends on your game, your string, and your arm. Come in and talk through it with us. That conversation is always free and always honest.

Can I drop off without an appointment?

Absolutely. Walk-ins are always welcome. Drop off your racquet and we'll call or text when it's ready to pick up.

My arm has been hurting. Can you help?

Arm pain is often a string issue. Come in and we'll look at your setup, tension, and string type. It's one of the most common things we help players fix.

What is racquet customization?

Customization is the process of tuning your racquet's physical properties to match the way you play. That means adjusting swingweight (how the racquet feels through the swing), calibrating the balance point, shaping the handle to your grip preference, and documenting the final setup so it can be replicated exactly. It's the difference between a racquet that's off the shelf and one that's built for you.

How do I know if I need a custom setup?

If you play regularly and you've ever felt like your racquet is fighting you — too heavy at the tip, too light in hand, inconsistent between two frames of the same model — customization is probably worth a conversation. It's not just for pros. Any player who cares about consistency benefits from a setup that's been dialed in. Come in and we'll tell you honestly whether it would make a difference for your game.
