The Chrystal Speed is a whole new string but made of 100 % pure
polyester = quality pure without any other additives
The string is intended for customers who do not want to play with modern softer
co-polyester strings but prefer the classic polyester strings (such as the
honey-colored Kirschbaum Super Smash).
The fact that the string is hexagonal
gives the ball more spin (= more spin or slice) in your hits
Information about the string:
Color: translucent
Shape: octagonal
Length: 12 m
Available thicknesses: 1.18 mm
