Tecnifibre

Black Code 16L

Tecnifibre Black Code 16L is the spin-focused polyester string from the brand that also makes some of the finest multifilaments on the market. The black oxide coating gives the string an enhanced textured surface that bites into the ball for strong topspin production, while the slightly softer co-polymer compound makes it more arm-friendly than many competing polyesters. Spin rated 8.5/10 places it just below Babolat RPM Blast, but comfort comes in notably higher — a meaningful difference for players who string up multiple times per week. Black Code is a favorite among club-level competitive players who want tour-level spin performance without the harshness of the firmest polyesters.
