Track is blowing bowlers' minds with the introduction of the Track Tour SiC. SiC stands for Symmetric i-Core. The proven i-Core design is taken to the next level by becoming symmetric because of its unheard of RG and Differential. Track has matched this core with the MR-6 Solid coverstock that is finished with a 500/3000 Abralon factory finish. This ball will provide a wide range of bowlers with a great backend motion and a reaction shape that hasn't been seen before on medium oiled lanes.
