SBS…what is it and why should we care?

We have made several posts regarding SBS, which is “String Bed Stiffness” and this is another one!

If you read this post we really need your comment(s), really!

String bed stiffness is the “feeling” when the ball hits the string on a tennis racquet.  Due to the various string materials there will be “soft” and “hard” feelings.  But wait, there’s more!

The string bed is made up of several strings, some longer called the Main string (M)and some shorter called the Cross string(X).  Using “reference” tension each of the sets of string will be pulled at the same machine setting!  It the machine is set at 50 pounds the tension head will stop pulling when it feels 50 pounds of resistance, regardless of what he tension inside the racquet head may be.

SBS is the most effective data for comparing tennis racquet stringing!

Let’s say you come into the world headquarters and we ask you what SBS you would like to have?  Would you know?  Probably not and not many would!  We have grown up using the term “reference tension”, not SBS.

Reference tension is “number” you would ask your racquet technician to set the stringing machine tension system on.  That number will probably be between 30 and 60 pounds (≈13 to 26 Kilo).

So, depending on many other variables, such as string material, string pattern, stringing machine, stringer technique, etc., you can end up with may different versions of the same “reference tension”.

A better way, and one we have been using for over thirty (30) years, is SBS but not everyone has bought into the concept, even though a qualified racquet technician will have a way to measure SBS!  Maybe because it is too much trouble to figure out what your desired SBS from machine X would be from machine A!  It is not!

There have been several really good SBS data collection devices but they have been difficult to use, and pricy!  Not to mention gigantic!

A call to action!
So here is where you come in,

Would you purchase a SBS data collection device?

How much would you pay for such a device?

Would you prefer a mechanical device or an electronic device?

The device must be portable, that is easily carried in a racquet bag or backpack

    Yes or It doesn’t matter

It must be easy to use.

If you use an SBS device would you use a racquet technician that did not know what SBS is or how to measure it?

Thank you for adding your comments to this discussion!  It is important stuff!

 

And The Winner Is…

If you know anything about Tecnifibre yo know they make some of the best multifilament strings in the business!

 

The winner is Tecnifibre MultiFeel 17!

This string, MultiFeel, is a very “soft” polyurethane bonded construction that offers playability and a good value!

Tecnifibre MultiFeel !7 Gauge

This graph shows the high elongation and nice elasticity of this string.  The fairly linear slope up to failure would indicate some consistency of shot all the way up to breakage!

The knot strength is pretty good for a thin multifilament and we can say from experience that the know is going to be fine when property “tightened” and large enough to not slip bak into the grommet barrel.

If you are considering a multifilament this would be a good one to try!

And the winner is…overview

Racquet Quest is going to add a “winner” of the week to our website as a way to develop a fun way to look at string!

Each week we will select a string that has exhibited outstanding properties from one of five (5) major categories:

    • Synthetic Gut
    • Mulit-filamanet
           Nylon
           PEEK
    • Natural gut
    • PEEK Monofilament
    • Polyester Monofilament

The winning string must have been installed in the most recent week either in a client or demo racquet.

We will include as much information as possible including graphs and the country of origin.

We will try to post “And the Winner is…” on Friday so take look!

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!

 

 

Dealing with Options, and What are the Options?

The little video you see above is just a reminder that we do not promote polyester based string for underage players!  So, what is underage?  Oh, under 100 would be a good number, I think!

OK, smart alec what are the options?

  • No Polyester

PEEK/Zyex

Well, there are many, however, if the option is only relative to “no polyester” the best option is PEEK material.  This material is usually referred to by the brand name Zyex which is the fiber division of Victrex of England and known by the Ashaway name as well.  This material is normally found as a monofilament construction as is most polyester materials.

PEEK/Zyex offers exceptional durability and energy!

Multifilament

  • Premium Playability

Natural gut still is the number one playing string available.  We use Babolat and Luxilon natural gut but there are other options like Pacific, Klip, and others.

  • Excellent Playability

Multifilament construction can act as a spring and return both performance, power, and comfort.  Typically the more individual fibers the better.  These fibers are usually bonded with a soft adhesive and show signs of “fraying” during use.

Strings in this category include Tecnifibre, Ashaway, Babolat, Head, Yonex, and Gosen and others.  Expect to pay $42.00 + for these strings installed.

  • Playability

These multifilament strings are typically constructed using fewer larger diameter fibers to enhance durability.  The same “fraying” occurs with this grade of string as well however the larger diameter will last a bit longer usually.

Strings in the category include Tecnifibre, Babolat, Head, Yonex, IsoSpeed, Gamma, and others.  Expect to pay between $35.00 and $40.00 for these strings installed.

Synthetic Gut

  • Value

There are probably 10000 strings that fall under this umbrella!  9999 of these strings will be a nylon core with one or two overwraps bonded to the outer surface.  This material and construction has been around for many, many years and has offered great service to millions of tennis players…and is still in major use today!

Strings in this category include at least one, and probably many more, set from every major brand!  If you are really cost-conscious do not overlook this material. Expect to pay $27.00 to $35.00 for these strings installed.
