Head Gravity Tour 98-Pre Release Version

Sep 29

Posted by

If you have listened to our latest podcast, you will know a little about the new Head Gravity Tour 98, to be released in January 2025!

Racquet Quest, LLC has the pre-release version and is excited to share what we can.

The difference between what you may see online and what Racquet Quest, LLC has is we have taken a raw racquet and applied the desired specifications to it.

We see this as a racquet suitable for many playing styles and levels, so we began with a swing weight of 321 and an overall weight of 327.

After Stephanie’s brief video about her reactions to this Gravity Tour 98 racquet, we will return to associate her comments with the numbers in our review! Wouldn’t that be fun?

In Stepahines’ video, she adds several years to the age of her Gravity MP, calling it 2003. Actually, it is 2023.

Now, here’s Stephanie!

Now, the numbers…

Head Extreme Team 2024

Jul 6

Posted by

The Head Extreme Team 2024 is the lightest of the Extreme 2024 Series and presents a 105 square head with a 16×19 string pattern…which means a very “open” string pattern!  This “openness” can contribute to spin.

Head Extreme Team 2024

The “openness” can also contribute to lower string bed stiffness and may return a little more energy to your shots

This racquet makes a perfect platform for customization if your game changes but staying with a 105-head size is important.

Is this Extreme or what!

Jul 4

Posted by

The new Head extreme series is here and it will not be ignored!  The citrus green color will make sure of that!

Head Extreme MP 2024

The Extreme series has been a very good one for us and our players and we believe this series will be even better!

Why?

This Extreme capitalizes on the big market for 100 square inch racquets but adds some performance advantages like a firm flex with proper flexibility in the shaft, a great grommet system with very deep and protective sections for the string.

This may be overlooked  but it should not be.

As you will see in the data this Extreme carries a lot of power to the court for you, and the string bed, with a dense center, can be adjusted to suit your game with out becoming too stiff.

The Extreme Series consists of:

The Extreme Pro 2024 98 square inch head and slightly heavier, slightly more flex, and a slightly lower swing weight.

The Extreme MP 2024 which is this review.

The Extreme Team 2024 which is a 105 square inch head indwell reviewed soon.

And my favorite the Extreme MPL 2024!    This is a 100 square inch head and a perfect weight to allow for customization to your specifications!  This will be reviewed soon!
