The Tecnifibre Black Code 200m Reel is one of the world's premier spin-enhancing co-polyester tennis strings, recognized for its pentagonal (five-sided) profile and comfortable, responsive playability. The five sharp edges bite into the tennis ball cover upon impact to generate massive rotational velocity and heavy, dipping trajectories that catch baseline corners.

Utilizing Tecnifibre's exclusive Thermocore technology, Black Code tempers high-modulus polyester to increase string flexibility, expand the sweet spot, and absorb harsh vibrations. Available in 1.24mm (17G) for extra bite and touch, 1.28mm (16G) for the ultimate balance of spin and control, and 1.32mm (16G) for maximum durability, this bulk reel is a staple for competitive junior and tournament players.

Key Features:

• Pentagonal 5-Sided Shape: Delivers sharp ball bite for explosive topspin, heavy slice, and high ball clearance.
• Thermocore Flexibility: Dampens harsh impact vibrations, providing a noticeably softer feel than conventional polys.
• Excellent Tension Retention: Keeps its playing characteristics and crisp response over prolonged hitting sessions.
• Three Precision Gauges: Available in 1.24mm, 1.28mm, and 1.32mm to tailor feel, spin, and durability to your game.
