Full Custom Racquets in Video

We want to have a discussion of “Full Custom Racquets” and this to be the best we can do at the moment!

Full custom components

Click on  Full Custom Racquet to see the short video, and thank you for watching!

We believe this is an exciting step forward in specialized tennis racquets and preparation.

We are anxious to hear your thoughts on this move to better racquets for everyone…especially you!

 

Head Graphene 360+ Gravity MP/Tecnifibre RPX

Normally our racquet reviews are when a racquet is brand new; however, this is a case where the updated string, RPX, from Tecnifibre is an excellent opportunity to add another review to the site!

There are some excellent reasons to review the same racquet again with different string or tension settings.

  •  It allows us to evaluate new strings for comparison purposes.
  •  It will enable the player to demo the same Racquet with a different string.
  • The string can affect the overall weight to a small degree but significantly impact swing weight.

For example, this racquet with Victrex 7718 PEEK string (15.9grams installed) has a swing weight of 318. With the new Tecnifibre RPX (18.0 grams installed), the swing weight is 325. That is not huge, but it is different.

Lead tape, commonly used to increase swing weight, weighs in at 2.8 grams for 12 inches! So, slightly over 2 grams of additional string weight in the strung area contribute to the difference between these strings.

Of course, this also means that swing weight can be reduced, somewhat, by using lighter string! We weigh all of the string we test for Power Potential, so we know which string can benefit either swing weight preference.

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!

 

 

2020 is Coming Into Focus!

2019 came and went in a blur!  In a few days it will 2020 and with it will come some exciting new tennis stuff, for sure!

I am not so good at predicting things but I do it anyway!  Here are a few predictions I will make for 2020:

  1. Tennis racquets will become more expensive, but only slightly.
  2. On-line sales of tennis racquets will increase.  See this previous post.
  3. Customer satisfaction with on-line sales will decrease.
  4. Small specialty tennis shops will be the source of information, then #2, and then #3.
  5. Players will stick with a racquet longer, making customizations as needed.
  6. String and stringing will become a more important component of a racquet purchase.  See below!
  7. Tennis related injuries will continue to be a problem for the sport going forward.

    No Underage Polyester, Please!

    Thank you for thinking about the “long term” for all tennis players!

    There are no bad strings just bad applications!

    The right equipment is crucial to the long term enjoyment, and winning, of tennis!

    The local representatives I deal with are committed to our “well being” even though some may feel like they are facing “extinction”!

    An excellent example of what we are talking about just walked in! Two (2) new racquets so poorly strung it is shocking!

    The customer is having serious arm issues with an excellent racquet, with a terrible string setup! But the string setup is probably considered by many to be the ultimate combination, that is RPM Blast in the main and VS Touch in the cross! That combination is coming out in a few minutes!  No more polyester!

    The quality of the stringing is what is so wrong! Had you or I received this racquet, we would have returned it at once! Why? Because it exemplifies the attitude of so many stringers that is “who cares”!

Happy New Year!
