Roto Grip · EP line
The Roto Grip Cosmos is a symmetrical bowling ball from Roto Grip's EP line, released in July 2026. It has the Clear Poly coverstock and the 3 Piece weight block, finished at 3500 Grit Polished out of the box. At 15 lb its RG is 2.69, with a differential of 0.006.
Among the 65 balls here with a 15 lb version, its RG is high, so it gets down the lane before it revs up, and its differential is low, for less flare and a steadier motion.
