The Complete Guide to GAMMA Momentum Tennis Stringing Machines

If you play tennis or coach players, you know that keeping your racquet freshly strung makes a huge difference. The right string tension can give you more control, power, spin, and comfort. But here’s the catch, strings lose tension over time, and trips to the pro shop can add up. That’s why more players, coaches, and stringing enthusiasts are turning to home stringing machines.


At GAMMA, we’ve built a lineup of Momentum Tennis Stringing Machines designed to make stringing easier, faster, and more accurate for everyone, from weekend players to seasoned stringers. In this guide, we’ll break down the full Momentum line, highlight the newest addition (the Momentum ST with spring tensioner), and help you decide which machine best fits your needs.


Why Stringing Your Own Racquet is Worth It:

Before we dig into the machines, let’s answer the big question: why bother stringing your own racquet?


  • Cost savings: If you restring multiple racquets a month, a machine pays for itself quickly.

  • Convenience: No waiting on shop schedules—you string when you need it.

  • Customization: You control tension, strings, and consistency to match your game.

  • Skill building: Many players find stringing oddly relaxing—like a pre-match ritual.

  • If you’re serious about your gear, owning a stringing machine is an investment that pays off both financially and in confidence on the court.

Meet the GAMMA Momentum Line

Here’s a quick overview of the Momentum family:


  • Momentum 2 – A reliable entry-level drop weight machine.

  • Momentum 6 – Upgraded features with more stability and precision.

  • Momentum 6 Plus – A premium drop weight with pro-level functionality.

  • Momentum ST (Spring Tensioner) – The newest addition, engineered for speed, consistency, and a smooth workflow.

Now, let’s dive deeper into each machine.

Momentum Line

Momentum 2: The Reliable Starter


If you’re new to stringing, the Momentum 2 is the perfect entry point.


  • Drop weight system ensures accurate pulls without fuss.

  • 2-point mounting keeps things simple for beginners.

  • Compact design makes it easy to store when not in use.

The Momentum 2 is for players who just want a straightforward, affordable machine that gets the job done without extra bells and whistles.

Momentum 6: Step Up in Stability


The Momentum 6 takes things up a notch for players who want more precision.


  • 6-point quick mount system stabilizes the frame better than a 2-point.

  • Drop weight system ensures accurate pulls without fuss.

This machine is great for someone who strings more frequently and wants extra durability and reliability without making the leap to a higher-end model.

Momentum 6 Plus: Pro-Level Performance at Home


For the serious player, coach, or small club, the Momentum 6 Plus offers pro-level features in a drop weight machine.


  • Diamond-coated clamps hold strings securely without slipping.

  • Quick-action clamp bases for smooth workflow.

  • Accurate Tensioning with the combination of fixed clamps and drop-weight mechanism.

The Momentum 6 Plus is designed for efficiency. If you’re stringing multiple racquets a week, you’ll appreciate the time it saves while delivering professional-grade results.

So, what makes it special?


  • Spring tensioner system provides consistent, repeatable pulls without needing gravity (like drop weights).

  • Faster workflow since you don’t have to reset a bar for every pull.

  • True-to-setting accuracy so you can trust the tension you dial in.

  • Quick swivel clamp bases that make locking and unlocking effortless.

  • Slim profile clamps hold strings tight with less pressure—meaning less wear on your strings.

In short, the Momentum ST delivers speed, efficiency, and consistency, all in one streamlined system. It’s perfect for players, coaches, and stringers who want professional results with less effort.

Drop Weight vs. Spring Tension: Which is Right for You?

One of the most common questions we hear is:

“Should I choose a drop weight or a spring tension machine?”


Here’s a breakdown:

Drop Weight Machines

  • Use gravity to set tension.

  • Super reliable and low-maintenance.

  • Affordable entry-level price.

  • Require manual adjustment with each pull.

Spring Tension Machines

  • Use an internal spring system for tension.

  • Faster workflow (no bar balancing).

  • Consistent, repeatable pulls every time.

  • Slightly higher price, but worth it if you string often.

Quick tip: If you’re just getting started or only restring once in a while, a drop weight machine will serve you well. If you’re stringing regularly (or even for others), the Momentum ST’s spring tensioner is worth the upgrade.

  4. Experiment with strings – Use different materials to find what fits your game.

  5. Enjoy the process – Stringing can be meditative, not just mechanical.
