Jacek Hankiewicz and Pawel Pietryja testing the stringster app
National coach Jacek Hankiewicz and Pawel Pietryja from Poland testing the stringster app. Both of them play a YONEX Duora 10 racket strung with YONEX BG 80.
While Jacek’s racket was freshly strung Pawel already played his racket on that day. And after only 1 day it had lost 1 kg of tension. Imagine how much the elasticity – and thus their “energy” – of his strings will have gone down after 1 week of training!
So use the stringster app regularly to identify the appropriate point of time to restring your racket!
