SiC (Symmetric i-Core) is the nucleus of the Track Tour SiC, one of the most unique balls in history. The i-Core has been poured with different densities in order to create a symmetric core, whereas the original i-core was asymmetric. This change in core densities creates the most unique numbers in a performance ball ever, providing great length and brilliant backend reaction. Transforming a core from asymmetric to symmetric is a revolutionary move and solidifies Track's position as the industry leader in bowling ball technology.
