The Tecnifibre Black Code 17g Polyester String Reel (660 ft / 200m) is a premium pentagonal polyester string reel engineered for competitive club players and heavy hitters who dema nd durability without sacrificing performance. Its unique five-sided geometry bites into the ball at contact, generating enhanced spin potential and a more precise feel on every shot. Unlike standard round polyester strings, Black Code's pentagonal construction also improves elasticity, which translates to a livelier response off the stringbed, a more forgiving sweet spot, and reduced shock transmitted to the arm at impact — a welcome combination for players who string frequently. At 660 feet per reel, it's an economical choice for coaches stringing multiple racquets or string-breakers who go through sets quickly. Black Code also performs exceptionally as the durability half of a polyester/natural gut or polyester/multifilament hybrid setup, pairing its tough wear resistance with the comfort and power of a softer main string.Color: BlackGauge: 17gType: Reel (660 ft/200m) Show more
