Designed for heavy to medium heavy lane conditions The "Train" features the S76 cover and NEAT -- E finish collaborated with a unique new core design that allow for unprecedented on lane performance. The all new symmetric "Combustion Core" contains extended protrusions from the body of the core that allows the Radius of Gyration (Rg) contours to be manipulated from their normal axis orientations within the ball. The altered Rg contours allow for a change in typical axis migration that yields more overall continuation down the lane. Coupled with the S76 shell and NEAT finish, this Train is sure to "Run 'em Over" !
