Yonex Exbolt 63 Badminton String

Exbolt 63 is the newest generation in Yonex's competition string family and the one a lot of tour players have switched to. At 0.63mm it sits between Aerosonic feel and BG80 power, with a Hard Vectran core that resists tension loss noticeably better than older thin strings.

Repulsion is high, sound is crisp, and the string holds its bed shape longer between restrings than anything else in this gauge. The clear modern-pro upgrade if you want thin-gauge feel without the every-other-week restring cycle.

• Gauge: 0.63mm

• Construction: Hard Vectran core, multifilament outer wrap
• Profile: high repulsion, crisp control, strong tension retention for the gauge
