Yonex Muse 100

We worked on the Yonex MUSE 100 today. Yonex presents the MUSE family as a way to make rallies more comfortable and enjoyable, and the MUSE 100 is one of the few Yonex racquets made in China. Its familiar Yonex isometric head sits on a frame that, at first glance, reminds me of the old “game improvement” category.  The Muse 100 looks bulkier than it is, maybe due to the color.

That Game Improvement label deserves a closer look. Many earlier game improvement racquets were light and stiff, with enough weight toward the head to help the racquet move through the ball. They were often marketed to beginners, though that didn’t always make them a good choice for a beginner.  The Muse 100 is different.

The MUSE 100 raises a different question: how easy is it to swing in play? Our measurements will help answer that. The HEAD Squared provides a useful comparison. The Head Squared swingweight is about 290, giving us considerable room to add weight for a player who wants more stability. The MUSE 100 we measured is higher, offering less room for that particular modification. That doesn’t make either racquet better for everyone; it just makes the starting point especially important.

The Muse 100, and we’ll show this in the numbers later on, as we will have some pictures up as well, is a heavier racket. I think you can look at the numbers in a minute, but the swing weight is right around 310 or something.  For example, the Head Squared is a 290 beginning swing weight. We think it needs to be a little higher, to be honest, but the point is that the Head Squared lends itself to modification for a higher-level player, I believe, more than the Yonex Muse 100.

The Muse 100 is very flexible, as you will see by the numbers, which is good for increased string bed stiffness while keeping effective stiffness down.

Look at the numbers, then look at the racquet.  There is also a Muse 98!

Is your butt cap squeaking?

In the last few weeks, we have had an unusually high number of squeaky butt caps come in for repair.

In a couple of cases, we received a text message asking if we could fix a squeaky butt cap.  In most cases, the answer is yes, but we need to know which racquet is squeaking and which version it is.

What causes the butt cap to squeak?

Destroyed Butt Caps

In almost every case, the staples holding the butt cap in place are the cause.

Ruined grip pallet

This stapling method has been used for many years, but the staples seem to be becoming more aggressive and fracturing the foam molded on the pallet.

So how do we fix it?

Our method requires removing the shattered section of the pallet.  In this case, we remove 18mm of the racquet pallet.

Printed Pallet Section

We design a model to fit the racquet and print it using a special filament that weighs the same as the removed foam.

Clearing the way for a new butt cap.

You can see the holes the staples created in the carbon fiber shaft.

We use a chemical bond to secure the printed section to the racquet shaft.

Although the chemical bond sets quickly, we like to let it “cure” overnight, if possible, before installing the butt cap and grip.

So, if your butt cap squeaks, we can fix it!

Time is Catching Up!

Most products that we are familiar with have a window of opportunity; we will call it that. The same holds true for tennis racquets as for cars, refrigerators, washing machines, et cetera.

What I want to talk about today is a racquet that was way ahead of its time, and now time is catching up. The racquet is the Head MXG series, specifically the 98 sq. in. player-style thin-beam racquet.

If you’re wondering why we are bringing it up now, after all these years, the answer is simple: the concept and execution are good and deserve recognition!

The important component, and the one that probably kept this racquet from being highly successful, is the Magnesium throat.  That is the silver thing that connects the shaft to the head of the racquet.  Most racquets have a similar component, typically carbon fiber, and normally not shiny.

However, the real performance component of this magnesium throat is the length of the ten (10) center main strings.  These ten (10) strings are nearly the same length, adding consistency to every shot and a more uniform string bed stiffness.

We have a few of the MXG 98s if you have never seen one and are in the neighborhood; stop by.  You can tell us what you think about it.

And other racquets that were ahead of their time.

 

Here we go again!

By now you probably know what is coming.

More numbers!
