Description
The Roto Grip Cosmos is a polyester spare ball built for a straight, predictable path to the pins. Its polished cover minimizes lane reaction, making it useful for spare shooting and very dry conditions. The sky, admiral, and teal finish gives this practical ball a distinct look.
Pin distance and top weight: Enter your preferences in the request box on this page before adding the ball to your cart. We will confirm whether your requested specifications are available.
Traditional three-piece core
The Cosmos uses a traditional three-piece core construction for stable, low-flare motion. Paired with its polyester cover, the core helps the ball stay on the line you choose instead of making a sharp move at the breakpoint.
