tennis racquet that string tension can be adjusted with handle
new tennis racquet design
New tennis racquet design that you are able to adjust string tension within the handle.
This may not matter much to the occasional elder player, however for the competition players it could make a big difference between serving and volleying. For example: less tension means more power, (rubber band effect). More tension means more control. Imagine serving with more power then while making the 3 steps it takes to get to the net, you are able to twist the handle to increase control for the follow on volley… a couple psi can make all the difference.
Problem this idea/invention addresses:
adjusting string tension on the fly. (while playing)
