The ultimate squash string for power and spin.
The Rough Diamond string has a unique combo of extreme power, max spin and extremely high energy return. It has a very good tension stability. The latter is made possible by using a newly developed material – HyperNylon - which offers improved polymer tension stability.
DoubleAR HyperNylon is produced through a co-extrusion process combining two different nylon materials, and finally applying a process to create a rough surface texture to add that extra spin on the ball.
Please note! Pre–stretch the string 5% when stringing the racket for best result.
The string is made in Italy by DoubleAR.
