A process which allows increased durability of string without the need of increasing the diameter or the composition of the string. It is the result of many years of research.

The Biphase process is a “pre-stretch” of the matrix in the production process

It results in perfect harmony and a optimial alignment of microfilaments inside the string.

-> Therefore : 20% added durability

Adapted for: The premium string (Xone Biphase)
