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

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!

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”!
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!

Head Graphene 360 + Gravity MP
The new Head Gravity MP seemed like the perfect place to start with this new series of racquets so that is what we did!
We believe this racquet falls between the Prestige and Radical series and will appeal to more players than either of those. Plus, there are two (2) 104 square inch models, the Lite, and S. These are relativley “thin” beam, (Lite and S = 24.4mm) racquets that Head has been missing, in my opinion, for a while.
It has a “flip” color scheme…one side is lava and the other is Miami Green (my word).
Head Graphene 360 + Gravity MP Lava Side
The head shape is a little more round. The weight is 312 grams (11.01 oz) which I think is a little light. The swing weight is 324 kg/cm² ( a good starting point).
The unique fiber layup is designed to “uncoil” at impact contributing to a new kind of power, and hopefully comfort.

The Series consists of a “Pro”, “MP”. “MP Lite”, “S”, and”Lite”. There is a Model Comparison post where you can see all of the racquets in one place.

This Gravity Will Not Let You Down!
The new Head Gravity Series of racquets is coming soon, as in mid July!
We are not supposed to post pictures yet but imagine a Head racquet with a more “round” head shape in a narrow beam design…and a new layup technique that allows the specific areas to sort of “unwind” at ball impact and generate comfortable power.
I believe the Gravity Series will appeal to a “hipper” Prestige player with the two color graphics package.
I will post more when I have complete specifications but in the meantime remember this Gravity will lift you up…not pull you down!
