Topspin Cyber Blue 17L/1.20 String Reel - 722'
Line: Topspin Cyber Blue
$79.90
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.

What players say
Tennis Warehouse customer feedback on this thin 17L gauge of Cyber Blue (722' reel) echoes the thicker gauges: players call it one of the softer, more arm-friendly polyesters around with strong tension retention and good control. The thinner gauge adds bite and a livelier feel, but a few reviewers found the 17L specifically too thin to hold tension consistently and said it broke fast or felt harsh on the elbow despite the string's soft reputation.
Best for
- Players wanting a thin, lively-feeling poly with less arm shock than typical co-polys
- Topspin players prioritizing bite and control over raw durability
- Players moving from synthetic gut who want more spin without full poly harshness
- Stringers who restring often and want a low cost-per-set reel
Pros
- Described as soft and arm-friendly, with some comparing the feel to synthetic gut
- Good tension maintenance reported by most reviewers, holding up across repeated sessions
- Thin 17L gauge gives extra bite and a livelier, more lively-feeling response than the 16 or 17 gauges
- Strong control and solid spin with plenty of pop for a polyester
Cons
- At least one reviewer found the 17L gauge specifically too thin, with inconsistent tension maintenance at lower tensions
- A couple of players still reported elbow discomfort despite the string's soft reputation
- Some reviewers felt it offered slightly less power than comparable Luxilon or Signum Pro polys
- Reviews found are pulled from the shared Cyber Blue customer feedback pool rather than the 17L reel specifically, so gauge-specific data is thinner

Amazing durability, lots of pop, great control, and plenty of power for a poly string.
— Alan, Tennis Warehouse customer review, Web
This plays very similar to any synthetic gut strings out there.
— Rene, Tennis Warehouse customer review, Web
Best performance, even better when you consider its price. Very soft for the elbow.
— John, Tennis Warehouse customer review, Web
17L Gauge is too thin. Poor tension maintenance resulted in inconsistent play...with the right tension, however, it delivered excellent power, comfort, control and spin.
— Brian, Walnut CA, Tennis Warehouse customer review, Web
Good tension maintenance, nice pop and durable. Just not kind to my elbow.
— Paul P, Tennis Warehouse customer review, Web
Extremely good power and great spin potential...simply a great string which I feel 100% comfortable with.
