The Tecnifibre Razor Code is a monofilament co-polyester string and offers an optimal mix of spin and durability. The Razor Code plays softer than traditional polyester strings, has more power and provides excellent shock absorption.

The string contains a co-polyester core and has a round shape. This string has ThermoCore technology, which increases elasticity for more power and a softer feel and the technology also provides extra shock absorption. The co-polyester composition provides more playing feel and tension retention than the first generation of polyester strings.

This string is available in different thicknesses. The thinner the cross-section of the string, the more elastic the string is, giving you more feeling and control. The thicker the cross-section of the string, the stronger and more durable the string is.
