Head Gravity Pro 2023

Head Gravity Pro 2023

Here comes the new Head Gravity Pro 2023, which brings some good stuff! Like a 100 square inch head with a string pattern of 18×20!

You will see more goodies when you look at the specifications!

This new Gravity Pro has a different “vibe” than last year’s model. ¬†Maybe it is the muted graphics!

The specifications will tell this is true “players” racquet!

Hint:  Swing Weight=338

You need to try this demo soon!  Trust me!

Head Gravity Team 2023

The new Head Gravity Team 2023 is last year’s Gravity S, a stellar racquet for many players! ¬†The 104 square-inch head fits a particular niche, and the modest stiffness will appeal to many!

The head shape on this 104-inch head is more round and nicely proportioned, which adds to the approachability of this model.

As usual, the numbers will tell the story, so look at the specifications!

This is a great option if you want something over 100 square inch head!

Head Gravity MP 2023

Close behind the new Head Radical comes the new Head Gravity 2023! Not one but three (3!). The Gravity Pro, the Gravity MP, and the Gravity Team!

This Gravity MP 2023 demo racquet is ready to hit today!  If you have not hit with a Gravity you will be intrigued by the weight distribution.  

We are starting with the Gravity MP 2023.

Head Gravity has always used a multi-color graphic package with one color on one side and another color on the other side.  This was clever, and many players liked the look.

The new models use a “color-shifting” graphic that you can see here. ¬†The colors are subtly different depending on how you look at the racquet.

And the graphic starts at the butt end on one side and starts at the tip on the other!  So it has a lot going on. 

The racquet is a 100-square-inch head with a fairly thin beam and deep throat shaft.

The string pattern is 16×20, which fills up the hitting area and produces a fairly dense pattern in the center of the racquet. ¬†This may contribute to a slightly longer string life.

Let’s take a look at the specifications

You may notice the stiffness of this racquet should be perfect for the control component of your game and be very arm friendly (see effective stiffness).

Head Radical MP 2023

You have seen the pretty pictures; now see the specs of this new Radical series!

We are starting our property review with the Head Radical MP 2023. ¬†The MP version will probably be the most popular due to the very lovely weight and “player” style head size of 98 inches!

Head Radical MP 2023

The Auxetic component should contribute to a comfortable but aggressive racquet.

As you look at the following specifications you may notice the addition of some “numbers”, specifically “beam width”. ¬†

We have been taking this number for many years but now believe it is time to expose it to you, the readers.  

Briefly, the beam height-to-width ratio contributes to in-plane stiffness which is important for consistent string bed stiffness (SBS).

Let’s Compare

We publish many racquet reviews that include comprehensive data to be used to speed up the selection process for players looking to review racquets and possibly demo them.

We thought it might be fun to do a little comparison of racquets in a simple format and we are starting with this one!

When considering racquets there is one “weight” that outweighs them all and that is swing weight! ¬†Swing weight is also described as inertia which is, in our discussions, ¬†the term used to describe the momentum of a tennis racquet. ¬†Once it gets going it does not want to stop which equals power (sort of F=MA)

compare

We will be adding groups of three (3) racquets whenever possible and when new racquets are introduced.

Weight is your friend!
