From the manufacturer

The Kingpin Gold Special Edition uses ECA-X Pearl (Enhanced Composite Adhesion), a pearlized version of the popular ECA-X cover to create length and a sharp backend in the Kingpin line. The Kingpin Gold Special Edition complements the line by creating less friction in the front part of the lane, and produces excellent recovery on medium conditions.
