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).

Head…just when you thought it couldn’t get any better

Well, we think it just got better!

The Head Radical has always been one of the best performance racquets available and doesn’t require much in the way of annual changes!

You can order yours now for the release date of February 9, 2023

We think this new group is right on target!  Adding Auxetic in the throat brings this series into the overall success of the Auxetic component!

We will be doing full reviews very soon, but in the meantime, take a look at these new Radicals!

The Team is the new “S” in the Radical Series!  Based on our initial testing, we think this model has a trick up its sleeve!

Head Graphene 360+ Radical S v21

From our perspective the Radical S should be one of the most used of the Radical Series!

Head Graphene 360+ Radical S

Why?  The 102 square inch head size is optimum for players looking for additional power,( and who isn’t) in a legitimate players racquet.  We say “legitimate” because this racquet can be turned into any thing you want, now or in the future!

As you will see in the specifications this is not a really stiff racquet so it will be easy for many players to customize the string bed to suit current playing style with an eye toward becoming a more aggressive player, or not!

The Radical S continues with the “control pattern” and “sound grommets”.  We are not totally certain what the “sound grommets” do but sound is frequency and frequency can be felt so maybe the grommets are damping out some of the higher frequencies?

Anyway, this Radical S model is a great step into the “performance” racquet arena with plenty of room to grow!

Head Graphene 360+ Radical Series Comparative Data

For 2021 there are Three (3) Radical Models!

Radical MP v21

A Close Look at Orange

The new, for 2021, Head Graphene 360+ Radical series is a radical step into colors that have always been the “mark” of the Radical Series but now it has gone even further into radicalism!

We think that is a good thing!  Why mess around with just a little orange when you can go all out!

It is impossible to see the vibrancy of this orange without holding it in your hand!  We invite to to hold one in your hand and even hit with it!

The Radical MP has been the most popular model over the years.  This model has all the attributes of the Pro without the added weight, (which can be added later if needed)!

The thin beam carries over to the MP and Pro while the S has a slightly wider beam.

The S model fits the very necessary range of 102 square inch racquets because Head has, correctly, reduced the number of head sizes per model.  The Speed series has the 100 square inch head size very well covered.

You will see all the specifications on each individual review that will be posted shortly.
