Head Radical for 2019!

The new Head Graphene 360 Radical series continues the “less is more” graphic package that is so popular on the Head Speed series. While I really like the occasional “Limited Edition” racquets I am favoring the new “look” now.

Head Graphene 360 Radical Series

As you can see there are four (4) models in the series starting on the left with the “Pro”, “MidPlus”, “S”, and “Power” versions. The obvious concept here is the minimization of graphics, however, not so obvious is the subtle color changes inside the head of the racquet.

I have compiled unstrung specifications which are important but not as much fun as racquet to racquet comparison which I will do between this series and the series of last year.

Unstrung Specifications

If you are interested in “approximate” strung specifications add 17 grams to the “overall weight” and 30 grams to “swing weight”.

So, until then enjoy the new Radical look!

I will be posting full reviews of each model by the end of the week so check back…and you can stop by the World Headquarters to examine these racquets yourself!

Instinct…get it!

The new Head Graphene 360 Instincts are in the shop waiting for your evaluation!


As you can see this new Instinct Series carries forward the “minimalist” graphics concept and a stunning blue color!  

If you have been shopping for a new Porsche lately you may have seen a similiar color they describe as “Miami Blue”!

The Instinct Series offers a MP, S, Lite, and PWR (Power) models. And, thankfully, and amazingly, these performance racquets are realistically priced!

I will be adding racquet specifications soon so come back or sign up for notifications so you won’t miss anything!

All Instinct models are at the Racquet Quest World Headquarters so stop by and take a look.

Here is a look the specifications of the Head Graphene 360 Instinct MP…

Weight is Your Friend!

Is this instance we are talking about racquet weight. Not the few pounds we put on yesterday, Thanksgiving Day!

In the early 1990’s we made a tennis racquet which weighed slightly over 7 ounces.  Awesome, some said!  This racquet traveled along with the standard weight racquets in the line and was available for anyone to hit with.

“Hit” in this case is a misnomer because the mass of the racquet was not enough to get the ball over the net in most cases!  Instead of a “hit” it was like a light “shove”!

With out a doubt the weight of a racquet must be “usable”.  Take a look at these brief warm-up videos to see weight in action then we will find out how much these racquets weigh and the swing weight…

Sophie Hitting

This is a Wilson Blade 98 18×20 pattern.  Racquet weight is  329 grams (11.61 Oz.) with a swing weight of 332 kg/cm^2.

Next let’s take a look at a different player…

Aleks (aka GBS) Hitting

This is a Head Radical with the Pro Cap System creating a racquet that weighs 340 grams (11.99 ounces) with a swing weight of 349 kg/cm^2.

It is obvious that both payers are swinging the racquet with gusto and it should be obvious that the racquets are stable on impact and this stability is necessary for power and control.

So the next time your oppponent asks if you have “gained weight” it will because the ball is coming at them with more “heaviness”!  And you can repsond “yes!” with a smile on your face!  Just like Robert, Sophie, and Aleks!

You Have Been Waiting for These!

You may not know it but you have been waiting for these!

Head continues with thier anniversary edition parade!  It seems twenty-five years is a good time to re-introduce the racquet(s) that made history then!

Head Radical 107

Head Radical 98 Limited Edition

The Head Radical 107 OS is a remake of the Andre Agassi racquet that is true to the characteristics of the era!   Great weight, perfect flex, workable swingweight, a 18×19 string pattern, a 107 square inch head, and minimal graphics!  This may be the purest example of a remake I have ever seen.  It even comes with the rubber band vibration dampers Andre used!

The Head Radical 98 MP is the newer racquet geometry and 98 head size.   The graphics reach back twenty-five years for the colors but the design is definately contemporary.  Plus, this racquet accepts the  Head Pro Player Cap System grommet set.  Yes, that means you can turn this Radical into a “beast” just like the previous versions!

I will be posting all the specifications of both of these as soon as possible but they are in the shop so please come by and take a look, and feel, for yourself.  These are limited edition racquets.

Turn the Head Radical Pro Into a Beast!

I am very happy to see players of every age returning to, or buying for the first time, racquets that have some weight!  Weight is your friend!  Any racquet can be “customized” to suit the needs of the player, of course.

But what do you do if you already own a Head Radical Pro?  You simply add the Head Players Cap System to your current Radical Pro.  This can be done the next time the racquet needs stringing and can be removed at the next stringing if wanted.

This is a “side by side” look at the Cap System Radical and the standard Radical.  You will need to like the color “orange”.

The Cap System can be added to many past Radical Pro racquets. The Cap System does not fit the Radical MP, unfortunately.

The image below shows the racquets and the specifications of each one.  You can see the difference between the two.  It is obvious that the major difference will be weight and swing weight.  The numbers between the two racquets are the data for the Radical Pro with the Cap System.

Turn the Head Radical into a Beast!
