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.\n\nThe 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.\n\nUnderstanding the 3 Piece Core and Polyester (Plastic)\n\nRoto 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.\n\nA Simple, Low-Flare Core Built to Go Straight\n\nThe 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.\n\nBecause 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.\n\nA Durable Clear Polyester Cover With Minimal Friction\n\nThe 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.\n\nThat 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.\n\nWho This Ball Is Right For\n\n✓Spare Shooters: A dedicated straight-line ball for converting single-pin and corner-pin spares with a repeatable shot\n\n✓New and Developing Bowlers: An affordable, predictable first ball, or a simple straight-shooting option while you learn the lanes\n\n✓Every Competitive Bowler: The standard plastic spare ball every arsenal needs alongside its reactive equipment\n\n✓Straight Players: A clean, no-hook reaction for bowlers who play straight up the lane\n\nGood to Know Before You Buy\n\n·Ships polished: The 3500 Grit Polish finish runs clean and long out of the box. For an earlier read on heavier oil, take the surface down at your pro shop.\n\n·Colors vary: Actual colors vary somewhat from the photos shown; no two balls come out of the mold exactly alike.\n\n·Tiny pit holes are normal: A few tiny pit holes in the coverstock are a normal part of the manufacturing process.\n\n·Sold undrilled: Ships without finger holes, so it can be fitted to your hand and span.\n\nBowlersMart Tips: Where the Cosmos Fits in Your Roto Grip Arsenal\n\nWhere It Fits in Your Arsenal\n\nEvery complete arsenal needs a dedicated spare ball, and the Cosmos fills that role. Where your reactive balls hook to the pocket, the plastic Cosmos goes straight, so you use it for corner pins and single-pin spares where hook only adds risk. It is the simplest, most predictable ball in the bag, and one of the most important for protecting your score.\n\nSurface Adjustments\n\nThe 3500-grit polish keeps the Cosmos clean and skidding straight. There is rarely a reason to change a spare ball's surface, but your pro shop can re-polish it if it ever loses its shine. Keep it polished so it continues to travel straight through the oil.\n\nCoverstock Care\n\nWipe the polyester cover with an approved ball cleaner after use. Plastic is durable and low-maintenance, so a quick wipe keeps the Cosmos shooting straight and looking sharp for years.\n\nEarn points on every Roto Grip purchase through the Striking Rewards loyalty program.
