Tecnifibre Fire 300

Tecnifibre Fire 300

The Tecnifibre Fire 300 is another great surprise from Tecnifibre.

Why a surprise?  This racquet shows up as a very stiff racquet both “out of plane and in plane”, as you will see in the following numbers.

However, the string pattern and spacing present a “canvas” on which you can create the string bed stiffness of your dreams!

Given the stiffness properties of this racquet, we wanted to test the “limits,” so we used a reference tension of 54, one less than the suggested 55 maximum.  Without going through all of the numbers, I can tell you that the Effective Stiffness is 26.7, which is well below our observed pain threshold of 30.0.

All of our demo racquets are strung with MonoGut ZX Pro (PEEK).  What you do in terms of string may change that number, but you can be sure the racquet stiffness can be mitigated by your choice of string, tension, and racquet technician.

Tecnifibre T-Fight 305 S

Jul 26

Posted by

Tecnifibre continues to excite us with some very nice racquets.  The T-Fight 305 S is the latest iteration and adds to Tecnifibre’s player-category racquets.

Tecnifibre T-Fight 305S

One of the first things you will notice is the depth of the white color!  In general, the finish of this racquet is as good as it gets!

Tecnifibre has included “knot locks” on the tie-off holes, so you will see four (4) black “mounds” around the selected tie-off holes.  This feature maintains knot tie-off tension and resistance to pulling back into the grommet.  An interesting feature.

This 98 square inch racquet incorporates an “open” string pattern perfect for those wanting increased power from the head size.  The string bed stiffness can be varied and controlled for players more focused on control.

As with many Tecnifibre performance racquets, the grip is of the “European” shape (flat) as opposed to the more “round” shape used by many brands.

Many of the full custom racquet clients we have prefer the “European” shape.

Take a Guess?

Jun 14

Posted by

A very good player and client came into the World Headquarters Wednesday with his three (3) Tecnifibre TF40 315’s wanting to re-string.  There is nothing unusual about that except this time he wanted to discuss different strings.  So we did!

The final three (3) strings under discussion were:

  • Tecnifibre Razor Soft 17 (current string)
  • Volkl V-Star 17
  • MonoGut ZX Pro 17

The first two are considered to be polyester, however, I am not sure V-Star fits entirely in that category, and PEEK is the material with the MonoGut ZX Pro name.  All of the strings are monofilament.

We learned in a previous post “a picture is worth a thousand words”, so we are  including a picture to help in our guessing.

Take a Guess?

Here are some basic properties of the subject racquet that may contribute to your guess

  • Weight=342
  • Swing Weight=327
  • RDC Flex=63
  • Flex Four Flex=50.8
  • Grip Size= 3

We hope you will make a guess in the “comment field” below and if you do you can use the string name or the color…we will figure it out, and thank you for you guess!

More Linearity

Mar 31

Posted by

Every string we use and even string we do not use goes through our Questron testing cycle.  We have discussed this before, and a video on this site shows the Questron in action.  We have updated the Questron significantly since the video was made…and it isn’t quiet.

We want to discuss “linearity” and how it can help when choosing a string setup.

We used these strings recently, and they were not chosen for any reason other than availability.

The first graph shows highly linear strings. The straighter the line from “0” to “fail,” the more linear and consistent the string is throughout its life.

 

 

 

 

So, what does linearity do for me?

  • Maintains tension
    • Minimizes energy loss
  • Maintains playability
  • Maintains consistency
    • Maximizes control
  • Maintains predictability
    • Provides confidence throughout your match

This property is essential to us. That is why we offer an alternative to non-linear strings.

If you would like this information for your favorite string, please let us know, and we will try to provide it for you nd all other readers!
