The Head Gravity Tour 98 is getting closer!
By now we suspect you have heard of the upcoming Head Gravity Tour 98 and may even have hit with it!
We have the pre-production model here, and it is being used enthusiastically. As you would expect, the feedback has been informative and interesting. We would like to invite you to add your comments, we welcome you to hit with our demo Head Gravity Tour 98!
Head Gravity Tour 98
Because we rely on numbers to help set up racquets for players, we need to know the numbers of the racquets being reviewed. Of course, we have those numbers for the one we have. Please note, however, that the swing weight numbers in the table are calculated, not measured.
This racquet, and the entire new Gravity line-up, will be available in January. We believe it will be a great launch of a fabulous racquet! The frame geometry and graphics are extraordinary! You will probably see pictures of it soon but photographs can not begin to tell the aesthetic story!
The new Gravity line is made up of:
| Model | Weight: Gram/Ounce | Swing Weight: Calculated | Head Size: Square Inch | String Pattern: Main/Cross |
|---|---|---|---|---|
| Head Gravity Pro | 315/11.1 | 302.7 | 100 | 18x20 |
| Head Gravity Tour 98 | 305/10.8 | 312.3 | 98 | 16x19 |
| Head Gravity MP | 295/10.4 | 311.6 | 100 | 16x20 |
| Head Gravity MP L | 280/9.9 | 304.9 | 100 | 16x20 |
| Head Gravity Team | 279/9.5 | 285.2 | 100 | 16x20 |

Head Extreme Team 2024
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.
