C300 Rally Bowling Ball

The Columbia 300 Rally is here to energize your arsenal and continue the legacy of one of Columbia 300’s most successful lines. As the high-performance follow-up to the popular Speed series, the Rally is engineered to offer a stronger, more controlled reaction while maintaining the versatility and consistency bowlers have come to expect.

At the heart of the Rally is the proven Shifter core, a dynamic asymmetric shape trusted for its stability, flare potential, and performance across a wide range of styles. This core delivers strong mid-lane read with powerful continuation through the pins, making it a reliable choice in high-performance scenarios.

What truly sets the Rally apart is its cutting-edge HK22 base coverstock, enhanced with Cohesion and Formula 1 additives. This powerful combination gives the ball extra bite on the lane, delivering outstanding traction and a smooth, controllable motion, even in medium to heavier oil conditions. The 2000 grit Siaair finish adds to its versatility, helping it read the mid-lane without sacrificing backend motion.

Whether you’re gearing up for league night or prepping for tournament competition, the Columbia 300 Rally is built to rise to the challenge.
