Topspin Cyber Blue 17L/1.20 String Reel - 722'

Offers the same great control and durability as Top Spin Cyber Flash string but with a softer and more dampened feel. Top Spin Cyber Blue (formerly called Cyber Power) offers improved tension maintenance and added comfort over many competing co-polyester strings. The thin 17 gauge offers lots of bite and a livelier feel compared to the 16 gauge version.
