Bolt 98L

The Bolt Racquet Series is back and in a very good way!

In case you don’t remember the Bolt racquets incorporate a patented Zip Strip that sits between the racquet and the string that mitigates the stiffness of the string bed somewhat.

I mention this because the In-Plane stiffness number you will see in the review shows a single number, and in fact for testing devices that number will be nearly the same with and without the Zip Strip interaction.

The Zip Strip will produce an “effective” hitting area larger than the measured racquet head size.
