Description (merchant text, shortened)
A Polished Polyester Spare Ball
About the Cosmos
The Roto Grip Cosmos delivers pure, predictable spare shooting in a striking Sky, Admiral, and Teal design. As a polyester ball, it travels straight to your target regardless of the oil pattern, so you can take the lane out of the equation and focus on hitting your mark. The Cosmos gives you absolute control over the tricky ten-pin and every corner-pin spare, the dependable straight-line tool every arsenal needs.
The Cosmos pairs a simple, low-flare 3-piece core with a clear polyester (plastic) coverstock at a 3500-grit polish. Plastic is the least aggressive coverstock material, so the Cosmos ignores the oil and goes exactly where you aim it, delivering the zero-board-crossing consistency that makes spare conversions repeatable.
Understanding the 3 Piece Core and Polyester (Plastic)
Roto Grip built the Cosmos to go straight. Specifically, the simple 3-piece core carries a high RG (2.68) and almost no differential (0.006), so the ball produces essentially zero track flare, while the clear polyester cover generates very little friction with the lane. As a result, the Cosmos holds a true, predictable line regardless of the oil pattern, exactly what you want when shooting spares.
A Simple, Low-Flare Core Built to Go Straight
The Cosmos uses a simple 3-piece core with a high RG and almost no differential, numbers that produce essentially zero track flare. That is exactly what you want in a spare ball: the core resists hooking, so the ball holds a true, predictable line straight to your spare.
Because it does not flare, the Cosmos rolls on a straight path regardless of the oil pattern. That predictability is the whole point of a dedicated spare ball: you can throw the same straight shot at every single-pin and corner-pin spare and trust it to get there.
A Durable Clear Polyester Cover With Minimal Friction
The Cosmos is finished with a clear polyester (plastic) coverstock at a 3500-grit polish. Polyester is the least aggressive coverstock material, so it generates very little friction with the lane. The result is a clean, straight reaction that ignores the oil and goes where you aim it.
That minimal friction is exactly why plastic is the standard for spare shooting. The Cosmos pushes straight through the fronts and resists the hook of a reactive ball, so you can line up your spares with confidence. Polyester is also extremely durable, making the Cosmos a long-lasting, dependable tool in any bag.
