Tecnifibre Black Code Performance
Tecnifibre Black Code is designed for players who want to maximize spin while maintaining control and feel.
Comfort & Feel
Comfort is above average for a polyester. Thanks to Thermocore technology, it offers better elasticity and shock absorption than traditional polys, making it more arm-friendly.
The feel is slightly muted with good pocketing, giving players a more forgiving response than stiffer alternatives.
Power & Control
Power is moderate. The string provides enough pop to keep shots deep but remains controlled enough for aggressive swings.
Control is very solid, with a consistent and predictable launch angle, helping players hit confidently under pressure.
Spin Potential
Spin is the standout feature. The pentagonal shape creates excellent ball bite, allowing players to generate heavy topspin and sharp angles.
This makes it ideal for modern baseline play with fast swings and heavy spin.
Durability & Tension Maintenance
Durability is strong. The co-poly construction holds up well for frequent hitters.
Tension maintenance is average to good. There is some initial tension drop, but the string stabilizes and remains playable for a reasonable period.
