Head Auxetic 2 Radical Team 2025
By now, you have probably seen the latest Radical series, which is very hard to miss. If you haven’t seen them yet, here is a peek at the “orangiest” of all racquets! These racquets look great and are perfectly matched to the Radical branding.
This review is of the Head Auxetic 2 Radical Team 2025, the lightest of the series with a 102-square-inch head.
Head Radical Team
When examining the following specifications, pay attention to the racquet’s stiffness. This flex may mitigate power but will open up a great combination for a player looking to take more control of the game.
The string we chose for this racquet is Ashaway Dynamite Natural 17 gauge (the color is a bright green, not natural). The material is PEEK fibers with a rough braided outer jacket, presenting a lovely COF if you care about these things.
The Radical has always been a great performance racquet, and this 2025 series is no exception. Come by the World Headquarters, get a demo, and tell us what you think.

Let’s Look at a Hybrid Graph
A client asked, ” Would putting natural gut in the cross string instead of the main string create a softer string bed?”
That question is the precursor to the graph below, so I will let the video tell the story.
This graph does not reflect the stiffness of polyester string. So, in any format, a natural gut may help soften the string bed if polyester is used.
