This innovative new string is produced in two production steps. Signum Pro developed a new heptagonal mould. With this mould a straight shape is produced in the first production step. After cooling down the string is heated again and then axially twisted in a second production step. The twist and double heating process makes this string very comfortable while the rough surface provides exceptional spin. The result of this new technique also offers a very nice combination of bite, power and comfort.
