Wow!  It is amazing what you can find when you break open boxes that have not been open for several years!  This discovery is a very happy one because this racquet was one of the very best that Kneissl produced, in my opinion!

There is so much to say about this racquet that is hard to know where to start.  So, I will start with the overall design.  As you can see the frame starts out very thin at the tip and increases dramatically as the shaft nears the grip area.  An interesting design feature shows the hoop area is triangular in cross section that increases to a wider dimension as it reaches the outside of the hoop.  If this seems familiar you are correct.  The Babolat Aero series used this concept.

Each of these racquet came with a blue plastic adaptor that fit the shape of the hoop and distributed the load of stringing over a larger area.

The Graphite/Fiberglass composite was a hall-mark of Kneissl manufacturing expertise and very few did it better.  The feel of this racquet was without equal.  The “30” refers to the percent larger this head is than a standard head of that era.

Around the outer periphery of the hoop is a groove for string protection plus an insertable “cover” that created the “Aero” dynamic feature.  Very cool!
