What players say

Trusted by New York's finest.

Tennis Lab FX is hands down the best stringer in NYC for me. When they just opened, I walked in looking for a lighter racket and with a ton of questions. Ana, the general manager, was super helpful steering me towards their demo program. That program was a game changer for me. It saved me from buying rackets I didn't need and helped me land on one I genuinely love hitting with and suits my play style. Now that I play a lot more I go back every few weeks. Ana helps me dial in the right strings and ideal tension. She really helps me understand what I'm looking for to help further my game. The whole team is patient, professional, and always full of thoughtful tips on tension, strings, gear, and rackets. Pro-tip: ask them about their own string — worth the conversation. If you're serious about your tennis (or just figuring it out like I was), this is the place. Can't recommend Ana, Johnny, and the Tennis Lab FX team enough.

These guys are the best. If you are like me, a player that is very picky with his tennis equipment, always looking for the perfect frame, and having identical racquets in his bag, look no further. Tennis Lab FX is your place. They can customize your racquets to make them identical, weight and balance, modify the grip shapes to your liking and string your racquets the same as the pros. I was never able to play with certain brands because of the grip shapes, but thanks to the team at Tennis Lab FX, they were able to change the grip shape of my Yonex Ezone frames to the same shape as the Head Speed Pro. What a game changer.
Wayne Johnson
I called Tennis Lab FX to get a recommendation for a tennis racket for my daughter who plays tennis 3-4 days a week. I spoke with Ana, who not only gave me several suggestions but also gave me a few pointers on how to choose a racket, find a weight that’s comfortable for you, and several other gems. Not only was she incredibly helpful and knowledgeable, but she also introduced me to their Demo Program where you can rent a few rackets and try them for a month to find one that’s the best fit for you. I’ll be giving this to my daughter as a Christmas gift, along with a few new rackets. Love, love, LOVE this place and can’t wait to grow with them as our entire family takes on tennis.

I can’t say enough good things about Tennis Lab FX. From the moment you walk in, you can tell these guys are passionate about what they do. The level of detail, care, and knowledge they bring to racquet stringing and customization is on another level. They took the time to ask about my playing style, tension preferences, and even helped me choose the perfect string setup to match my game. The turnaround was super fast, the quality was flawless, and my racquet has never felt better on the court. If you’re serious about tennis — whether you’re a competitive player or just love the game — this is the place to go in New York City. Professional, friendly, and incredibly knowledgeable.

I had an excellent experience here — the staff really know their stuff and took the time to help me find the right racquet setup for my game. They strung my racquet perfectly and even gave some helpful tips on tension and grip size. I’m definitely no tennis pro but they treated me like one. Highly recommend for ballers of all skill levels.
