Racquet customization has been around since the early days of tennis. Players at every level have learned that small adjustments to weight and balance can completely change how a racquet feels and how it performs. While in the past, racquet tuning required lead tape, putty, or the hands of an experienced technician, new innovations have made customization easier, more affordable, and more efficient than ever.

Solinco’s Weight Control Module (WCM) is a simple, intuitive system designed to let players fine-tune their racquets in minutes. Whether you’re chasing more maneuverability, improved stability, or just experimenting with how your frame feels in your hand, the WCM puts control back into the player’s hands.

WHY RACQUET CUSTOMIZATION MATTERS

Every player has unique needs based on their swing speed, style of play, and performance goals. For example:

• Aggressive baseliners may want added stability to stay steady on heavy groundstrokes.
• Serve-and-volley players often look for more maneuverability at net.
• Recreational hitters might benefit from subtle tweaks that reduce vibration and make the racquet feel smoother.

Customization lets you take a stock racquet and make it feel like your racquet. And while most pros rely on highly customized frames, recreational players can now make similar adjustments without needing a racquet technician.

WHAT IS THE SOLINCO WEIGHT CONTROL MODULE

Developed in partnership with racquet customization expert Roman Prokes during the creation of Solinco’s Whiteout and Blackout lines, the Weight Control Module uses a trap-door butt cap system. Instead of relying on lead tape or professional customization services, players can easily swap out the butt cap plate at the base of the racquet to instantly adjust its weight and balance.

The module comes in 5-gram and 10-gram options. Simply pop out the stock butt cap and replace it with one of the weighted plates. The change shifts the racquet’s balance to be more headlight. That small adjustment translates into noticeable differences in stability, comfort, and feel on court.

HOW THE WEIGHT CONTROL MODULE WORKS

The WCM is all about simplicity. Using just a screwdriver or even a pen, players can pop open the trap door butt cap, remove the standard plate, and click in a weighted option. No adhesives, no permanent changes, and no risk of damaging your racquet.

On court, the difference is immediate. Adding weight to the handle shifts the racquet’s balance, making it easier to whip through contact while still feeling stable against heavy pace. Players who tested the system found that the 5-gram module added subtle stability, while the 10-gram plate provided a more significant shift, creating a racquet that felt steadier and more connected to the ball.

The best part? If you don’t like the feel of it, you can always switch back.

WCM VS. TRADITIONAL CUSTOMIZATION METHODS

For years, racquet tweaks meant lead tape strips at 3 and 9 o’clock, silicone injections into the handle, or custom jobs that required hours of work and permanent changes. While effective, those methods aren’t always accessible or reversible.

The Weight Control Module solves that problem. Instead of layering tape or committing to a one-time modification, players can test both the 5-gram and 10-gram options in minutes. It’s cleaner, faster, and designed specifically for Solinco racquets.
