Who is the Tecnifibre Blackcode best suited for?

Polyester (co-poly) is the choice for advanced players with full swings who want control, spin and durability. It's best suited to mature players - we don't recommend full-bed polyester for juniors or anyone with arm issues.

What does the 1.24 mm (17 gauge) gauge mean?

The 1.24 mm (17 gauge) indicates the string's thickness. This is a medium gauge, balancing feel, spin and durability - a popular choice for all-round play.

What tension should I string it at?

The recommended tension range is 48-55 lbs (22-25 kg). String toward the lower end for more power and arm comfort; higher end for tighter control.

How long will this string last?

This is a durable string that should last most club players 25-40 hours of play or around 2-3 months of regular use before losing pop.
