Head Lynx Touch! Two for One?

Several weeks ago we received the first sets of Head Lynx Touch 17 gauge strings.  Yesterday we received the Lynx Touch 16 gauge version and want to share the differences…numerically!

Quickly, this string is composed of two (2) separate but “combined” filaments.  So, is this a monofilament or a multifilament?  The numbers indicate it reacts like a monofilament as we have become familiar with it.

Visually the string components are obvious.

The inner filament is black and the outer covering is translucent.

 

Let’s start with the 17 gauge version:

  Lynx Touch 17

The area under the heavy red lines is the “stress/strain” curve and we see that this string takes 23.5mm to reach the 50-pound mark.  This is just a number unless it is compared to other strings so it is neither good nor bad, right now!

You can see that the string will hold up to 149.8 pounds before it breaks.  This is tensile strength and may be important when considering the amount of “notching” that can occur.  The “knot” strength of this version is 132.4 pounds.

Now let’s look at the 16 gauge version:

Lynx Touch 16

The difference is subtle.  The 16 gauge version is a little stiffer (expected) and a little stronger in tension  (also expected).  The “knot” strength of this version is 133.6 pounds.

What is interesting is the “grouping” of the stress/strain cycles on both strings.  They indicate a good elasticity.  The closer to the “zero” point on unloading the better!

In our opinion, both versions of the string would be considered “stiff” and suitable for the player looking for a stiff but stable string as our creep test confirmed.

If you currently use stiff strings and would like better consistency this would definitely be a candidate ./

What is an Over-Grip for?

Well, it seems pretty clear that an overgrip is intended to keep the under-grip in good condition for a longer period.

Consider an under-grip of synthetic material that will cost about $15.00 installed and an overgrip is about $1.00 (we put one on for free with every racquet we string). Is it because we are so nice or because we don’t want to spend a lot of time handling your old overgrip! It could be both!

New Over-Grip!

If you listened to the latest Racquet Quest Podcast you heard about our upgrade from Yonex Super Grap to Head Prime Tour overgrips! Why?

There are several reasons but a major one is the packaging of the Head overgrip helps with our efficiency of handling and installing an overgrip. It sounds like a small detail but it is important to us. Plus, the material of the Head Prime Tour is very effective in what it is intended to do!

So, why don’t some players ever change their overgrip? We don’t know! Do you? If so please tell us.

Old Over-Grip!

If you need help installing your overgrip you are welcome to come by the World Headquarters and we will do it for you.

Over-grips are cost-effective enhancements to your racquet grip and your game!  So, get a good clean grip on your racquet!

String Evaluation Program

Racquet Quest, LLC has for years been doing the extensive evaluation of racquets and string for the benefit of our client’s customization requirements.

Now we are making this evaluation “program” available to anyone that wants to dig deeper into the workings of the string in the racquet!

This is serious stuff and requires significant resources but it is worth it!

Please contact us of you would like to take advantage of our evaluation program!

Take a look at the String Evaluation Program!

 

 

Still Committed to Your Racquet!

For the past few years and certainly the past year Racquet Quest has been committed to tennis racquets and yours is included!

Hopefully the days of the “mask”are over and we can resume actually talking to each other and be understood! Of course if you prefer to wear a mask that is OK, too!

Here is what is not OK!

Not caring about your tennis racquet is not OK, and by that I mean keeping it in the best possible condition. That includes string, grip, grommet sets, overgrips and general reactions of beating it against the ground or net!

We have seen five year old racquets that look brand new and five day old racquets that are in really poor shape! One of the most damaging “strokes” in tennis is the ball pickup stroke! This is not a stroke at all but a way to keep from bending over to pick up balls!

Using the racquet head to scoop up the balls is easy and cool! It is also the quick way to ruin the bumper guard which is there to protect the Racquet from normal stroke, not pick-ups!

So, what do you do about it? The next time you consider scooping up balls with the racquet consider tapping the ball to start it bouncing or simplpy use the fingers on your hand to pick up the ball…that would be good!

What Can String Failure Tell Us – Part Deux

In Part Un we discussed the difference between shanking (mis-hit) and friction failure.  It was obvious that the string was broken.  But what happens when it is not so obvious?

Part Deux, this part, will examine the frictional notching failure of monofilament string and how we can be prepared for it!  To further refine this discussion we will be comparing PET polyester has PEEK monofilament string.  The reason is that each material while both will notch one requires more time to reach the critical dimensional decrease that is a failure!

In almost every Racquet Quest Podcast we talk about tension v string diameter and agree that once 50% of the string diameter is notched away the string is vulnerable!  So a .050 (1.27mm) diameter string that has a tensile strength of 120 pounds at 50% notching will have 60 pounds of tensile strength remaining.

Notched v un notched string

This graph is a string that was broken during use.  The string was removed from the racquet.  The top line is the tensile strength in the area of no notching so you can see that it is pretty strong still and has stabilized due to use.  That stabilization is indicated by the very tight stress/strain grouping.

However, things go sideways when the notched area of the string is put under stress.  The string failed at a force of 63.8 pounds, or about 59% of the used tensile strength.  Not bad!

So, notching is failure-inducing but how long it takes to create the fatal notch differs with string material.  This particular set of strings had about six (6) hours of play.

In Part Trois, we will look at PEEK material under the same conditions!
