Head Graphene 360+ Gravity Tour

Head is adding another racquet to the very popular Gravity Series!  This racquet is the Gravity Tour and in a nutshell, is a lighter version of the Gravity Pro.  Both are 18 x 20 string patterns and, the Gravity Tour is a 22mm beam as opposed to a 20mm beam for the Gravity Pro.

Head Graphene 360+ Gravity Tour

You would think the 22mm beam would be stiffer (power?) than the Gravity Pro, but in this case the extra weight of the Gravity Pro makes it a little more power forward. Our tests show the RDC stiffnesses to be the same (60), and the FlexFour shows the Gravity Tour slightly stiffer in the shaft, 51 as opposed to 46 for the Gravity Pro.

From a numbers standpoint this racquet (14 grams lighter) will fit a player wanting a little more maneuverable racquet but not as powerful as the Gravity Pro. ← Click on this link to see the review.

This review is of a “play ready” racquet.  That is an over grip, and vibration damper.   These accoutrements do contribute to weight and swing weight to a minor degree.

New Head Racquets on the Way!

While we are not supposed to publish any specifications or images, we can certainly let you know that some new things are coming from Head.

Frequently we are asked, “when is a new Prestige coming”? Now we can answer that by telling you it will be in January 2020. Of course, you will be able to try them before then, but January is the ship date.

We have seen and worked on the racquets, and I can tell you the graphics package is incredible, in my opinion!

In addition to the new Prestige in January, a new Speed is coming in March 2020.

We will post more information as we can so stay tuned!

Head Graphene 360 + Gravity S

Here is where it gets interesting!  This racquet, the Gravity S, is a realtivley thin beam 104 square inch racquet!

It has been a while since Head has presented this head size in a player oriented racquet!  This 296 gram (10.44 ounce) racquet fills a serious need, in my opinion, for a “players” 104!  The 24mm beam allows the stiffness to reflect the new “Spiral Tech” fiber placement.

Model Comparison

I believe this racquet will appeal to serious adults seeking a comfortable racquet  (RDC 56 strung) that can elevate their game.

This racquet has plenty of “cutomization” potential which makes it great choice for quickly advancing players.

Stop by and feel this combination for yourself, and take the demo for a real test on the court!

Head Graphene 360 + Gravity MP Lite

The Gravity MP Lite as you would expect is lighter than the MP by about a ½ ounce with a corresponding reduction in swing weight.  This can be easily remedied by increasing the swing weight while not effecting the ovefrall weight very much.

The MP LIte is a great example of a “customizable” racquet and deserves great consideration by any player seeking a performance racquet that will stay with them for a long time.

Model Comparison

The head size of 100 square inches is consistent with the Pro and MP models.

Head Graphene 360 + Gravity MP Lite

 

These are not the same racquet but the entire series uses the  two color graphics package with Lava on one side and Miami Green (my words) on the other.  Sort of a fun point!

Take a look at the specifications that follow.

Head Graphene 360 + Gravity Lite

If you guessed the Lite is the lightest model in the Gravity series you are correct, but did you guess  it is also a 104 square inch head?  Two 104 models in the series!  I say “way to go”!

Model Comparison

Head Graphene 360 + Gravity Lite

The 16 x 20 string pattern remains but the spacing is slightly more “open” than the “S”.  The “Lite” is slightly stiffer than the “S” therefore a slightly higher power calculation you will see in the specifications.

The “Lite” can be the perfect racquet for those looking for a 10 ounce racquet, and whose game is “settled in” and are not looking to make a bunch of stroke/technique changes!

The “Lite” will come in the smallest grip size of any Gravity model which is important when fitting a smallish person with a performance racquet!
