Tecnifibre Makes a Move!

Does Tecnifibre have the “answer”…again?

We all know Tecnifibre for its terrific multi-filament strings that set the bar for strings of the material and construction.  Several years ago Tecnifibre introduced a string that was intended to be arm friendly to counter the increased use of very stiff string.

Since that time Tecnifibre has gotten into the polyester string arena in a big way but they have not forgotten the player that needs a more comfortable string.

Not long ago Tecnifibre introduced Duramix 16 and 17 gauge string.  As the name implies there were a couple of fibers used to create a stiffer but still comfortable string.  We have used, very successfully, the Duramix 16 and 17.  This is a great option for juniors that need some durability without sacrificing their arms.

Now Tecnifibre has introduced Triax!  Is Triax the new “answer?”

Triax will replace the Duramix name but deliver the same or better performance and comfort.

Take a look at the String Characteristic Data to see how these new Tecnifibre strings stack up!



Weight is Your Friend!

If you have been following the Racquet Quest Podcast you know how much we rely on weight to mitigate some poor shot execution or physical issues!

So, don’t be surprised if that position continues for a while!  It is majorly important now that we are beginning to play (openly) again!

It is not clear to me why some players object to even discussing weight let alone add it to their racquet!

The latest podcast episode, The String Holder – Part Two, focuses on three (3) players of about the same age and skill and looks at the differences in racquet setup including weight.

If weight is so scary why do most racquets have a bunch of it hidden away from us?

This is a Tecnifibre racquet however most performance racquets will have a similar setup.  Game Improvement (ultralight) racquets, typically, will not!

What you see in that groove is lead!  If you flip the racquet over you will find the same thing on the other side!  Lot’s of lead means lots of weight, relatively speaking!

If we wanted to reduce the weight of this racquet we could remove some or all of the weight without affecting the swing weight very much.  The static balance, however, would be very different.  That is why we don’t rely on “balance” as a performance metric.

In the case of this racquet, we are printing a grip pallet that will replace the original pallet but be heavier so we can remove some of the lead weight to make the new version the same weight if we wanted to.  We don’t want to!



String. What is important?

The essential function of string in your tennis racquet is to return energy to the ball as it collides with the racquet. It is evident that if there is no string or a broken one, the racquet can not do what it is intended to do, and your shot is going nowhere or worse, everywhere!

There are about thirty (30) string brands, and each brand has about ten (10) different models, and maybe three (3) different colors, so there are nine hundred (900) possible selections! Nine hundred is way too many strings!

You and we need to consolidate string data so we can make the right decision for you, your playing style, and your physical capabilities.

We test every string for elongation, creep, (stability), with a little bit of elasticity data observed. This testing returns our exclusive Power Potential© for each string, and that is the basis of our decision-making process. Naturally, the higher the elongation, the more power the string will return to the ball, and conversely, the lower the power potential, the less power that “can” be generated. You can observe this fundamental by dropping a tennis ball on a concrete floor and then on a strung tennis racquet from the same drop height and see which one bounces the highest.

I use “can” because power, to a great extent, comes from how hard you swing the racquet, which, of course, brings the prospect of overdoing it and subsequent injury! A low power string demands a more powerful swing that involves the entire arm, hips, and legs.

Low power, in the form of a stiff string, has been associated with control, therefore, the increased use of stiff strings. However, with stiffness comes another downside, and that is stability. Stiff strings typically lose tension quickly and need to be changed frequently. So here is the real problem; the string may not be broken, but it is not playing well at all. There is a difference between durability and performance! If your goal is long term performance, a stiff string is not the answer.

What, then, is the answer?

Choose a string with an elongation of 10% or higher! Oh, great! You say. How am I going to know that!

Well, beginning January 1, 2020, I will be posting the power potential of every string we have tested over the years! There are over 500 items on the current list sorted by brand. The color coding is RED if 5% or less, GREEN if 10% or higher, and BLUE for everything else. Note, however, that natural gut is included in this data and will probably not reach the 10% Power Potential© threshold, but is still the best performance string available.  This is due to the dynamic properties of the natural fibers, so, until there is a separate classification gut will be included as is.

A previous post, “What is Soft?” goes into graphical detail.

As new strings are added, some older ones may be deleted because they are no longer manufactured. However, some very old ones may remain due to their “legacy” status. This chart is a preliminary format but will get us map toward the right decision!

Tecnifibre T-Fight 315 XTC

Tecnifibre has been making racquets for some time and it has taken some time for the racquets to gain traction!   For years the racquets played off of the success of Tecnifibre strings!  “If the strings are that good the racquets must be good as well”…was the thinking, I believe.

The racquets are able to stand on thier own and the relationship with the Lacoste brand certainly has helped from a “brand” perspective.  Did Lacoste change the logo from the triangle to the stylized TF!  I wonder?

The racquet continues the red, white and blue (French colors and the home country of Tecnifibre) graphics package and they look good!  The white basic color makes the shaft look a little bulbous, in my opinion, but that has no bearing on performance!

The T-Fight XTC series offers racquet weights of 280, 295, 300, 305, and 315 grams so there is one for every level!

Even Danil Medvedev!  If you watched the US Open you saw, in my opinion, one of the best of the year!

Take a look at the specifications then come in and try this racquet!

Tecnifibre T-Flash 285

As I was working on this racquet I am thinking about the category in which this will be placed by me, and others probably, and I need to put it in the “game improvement” category!

Typically “game improvement” racquets are very large, ultra light, head heavy, and stiff!  The T-Flash falls into this category because it is stiff!  None of the other characteristics apply!

This racquet has a stiffness of RDC 70!  This compares to the Wilson Ultra, and the Babolat Pure Drive, except it is not as heavy as either of those racquets.

To me the weight is an issue that can be remedied, and the very open string pattern mitigates the stiffness and keeps the effective stiffness below 30.

If you are considering a “power” oriented racquet this one should be on the list!

Adding Ashaway MonoGut ZX string to the mix assures the player of comfortable hitting!

Take a look at the specifications… then hit with it!
