Countless hours of Research & Development for the Dark Matter yielded a brand new coverstock for the 900 Global brand… the S60 Solid.  The use of friction enhancing additives in our S43 shell mutated it into the S60, creating additional chemical bonding sites in its urethane formulation.  What does this do? – increased response in the back part of the lane! Combined with the Dome Symmetric core, the Dark Matter will provide a new shape in the 900 Global line in between our Preferred and Select Series.
