Star Core Technology
Six equally spaced 60 degree ridges around a circular body offers the best possible combination of ball bite and minimum string to string friction. Solstice string has a larger surface area then a round or edged string with the same diameter, due to the geometric properties of a star (hexagram) shape. Furthermore, the sharp points of the Solstice string combine with the enhanced friction due to surface area for lethal bite.
Conversely, the Solstice shape allows for less friction between the cross and the main strings due to minimum contact as the points of the star interact with each other. This reduced frictions results in explosive snap back, a key component in spin generation.
This phenomenon takes place regardless of the gauge, as the edges come to the same 60 degree angles no matter the diameter of the overall string. Therefore, extreme spin is capable with any gauge of Solstice strings. Our Star Core Technology is found in all our Solstice line of strings, and is Patent Pending.
Our string uses a proprietary extrusion process for long lasting tension maintenance. The process requires an exact temperature controlled quenching system and has enhanced the playability of our strings. The unique material compound was designed and enhanced with special additives for dynamic comfort.
We have designed the most unique balance of comfort, performance and spin on the market. Don’t believe it! See our test results from USRSA.
