Atlas Solid The Atlas Solid is the newest powerhouse in the Columbia 300 lineup, built for bowlers who demand big hooking performance on tougher lane conditions. At the heart of the Atlas is an all-new Atlas core, engineered with a higher RG, differential, and intermediate differential than the Speed core. This design promotes a strong, dynamic motion that delivers an exceptional backend reaction while maintaining powerful continuation through the pins. Wrapped in the aggressive Formula 1 Solid coverstock, the Atlas Solid is built to handle medium to heavy oil conditions with confidence. Finished at 500 / 2000 Siaair, the surface provides the traction needed to read the lane early without sacrificing down-lane motion. With its combination of strong core numbers, aggressive coverstock, and proven surface prep, the Atlas Solid is a true heavy-oil performer that brings power, control, and pin-driving strength to any competitive arsenal.
