Tecnifibre Black Code 12m

The five edges of the Black Code section work for spin, making deep topspin and short angles easier. Co-polyester handles control and durability, and Thermocore makes it gentler on the arm, which is why Tecnifibre promises comfort along with spin. The thinnest gauge, 1.18 mm, gives more feel and bite, and the thickest, 1.32 mm, lasts longer. Recommended tension is 22-25 kg, with 32 kg as the limit.
