The newest addition to the MX line, designed for medium rev bowlers, is the Track MX16! The Mx16 is designed to be a smoother, earlier rolling and slightly stronger pair for the Mx10. We've utilized our i-Core in order to provide strength in oil but won't outhook the transitions for medium rev bowlers. The MR-8 Hybrid Coverstock provides a smooth, versatile reaction on medium-heavy conditions.
