Tecnifibre Razor Code
High Modulus Polyester Compound with Thermocore technology
Performance ratings
Overview
Razor Code is the most resistant and hardest to deform string in Tecnifibre's range. The High Modulus Polyester Compound ensures a firm feel and extreme durability, making it the top pick for performance players and heavy hitters. Thermocore technology brings flexibility despite the rigid material by using heating and cooling phases. Playtesters found excellent control (8/10), good feel (7/10), and surprising power for a 16 gauge co-poly. The Blue version is softer than White with a little more pop. Recommended for rackets over 300g.
