So unfortunately I clashed rackets with my partner during a doubles match and resulted in this crack on the 11 o'clock area of the frame. I'm kinda worried that if i keep using it, the racket will break. What can i do to strengthen that area? Like if i rubbed a bit of super glue over the crack, would it help?
Yep, that racquet is done for. Once you break the strings of that racquet, it won't be able to withstand another string job again because the structural integrity is gone. I'd recommend you retire that racquet while it's still in one piece if you want to keep it as a memento.
You can try a 2 part EPOXY available at Walmart, Canadian Tire, Home Hardware. Basically get that epoxy on the crack and it "could" help maintain the structural integrity.
