Wilson ProStaff Classic

0 Flares Twitter 0 Facebook 0 0 Flares ×

This racquet was used by so many Wilson Pro Players it is impossible to find a player image that will do it justice! It looks like the very racquet that Stephan Edberg used for most of his career.

This is not a West Indies version but appears to be one of the first models manufactured in Taiwan. This racquet proudly presents the composition on the shaft as 80% Graphite + 20% Kevlar™

This racquet is unique in that it does not have a “stiffness index” on it anywhere. The SI is normally something like 6.0, 6.1, etc. As you will see in the data below this racquet is not ultra stiff.

As with many of the “ProStaff” racquets this one is fitted with the famous Fairway grip. This is truly the “Classic” ProStaff.
