The Tecnifibre Razor Code 17G/1.25m Tennis String is a co-polyester string designed to provide the benefits of a traditional polyester string with a slightly softer more comfortable feel to it.
You get the spin potential and control of a polyester string but with a bit more feel and touch. Compared to a traditional polyester string Razor Code also provides more power. This 17g version is slightly thinner than the 16g version, meaning you get great levels of feel, but, the string may be slightly less durable in comparison.
For the advanced player, Tecnifibre Razor Code could be used in a full-string bed, and, it would also make for a main string in a hybrid setup with the crosses being a softer multifilament or natural gut string.
