Every lineup needs a reliable co-pilot — the Cosmos is yours. Built for every interstellar style of bowler this side of the Milky Way, the Roto Grip Cosmos pairs out-of-this-world looks with rock-solid spare-shooting function. A clear polyester cover wrapped around a traditional 3-piece core means this space rock holds the line you send it on — no hook, no surprises, just deck-clearing accuracy shot after shot.

When the 10-pin is staring you down and the match is on the line, you don't want drama — you want a ball that goes exactly where you point it. That's the Cosmos. Straight as a laser beam, pretty enough to turn heads on the approach.

Who It's For

• Spare specialists — the go-to for shooting corner pins. Zero hook means what you aim is what you get, every single time.
• Two-handed & high-rev players — kill the axis rotation on your spare shots so your strike ball's power doesn't wreck your accuracy.
• New bowlers — the easiest way to learn a repeatable, straight spare game without fighting an aggressive reactive cover.
