Columbia 300 Rally Hybrid Royal Blue/Lime/Silver Bowling Ball

Ready to rally your game? The Columbia 300 Rally Hybrid is your ultimate all-condition weapon — built for precision, power, and proven performance.

As the follow-up to the popular Speed series, the Rally raises the bar with the asymmetric Shifter Core — one of Columbia 300’s most trusted core designs. This dynamic shape delivers a strong mid-lane read and powerful backend finish, offering confidence and control from release to impact.

Paired with the HK22 base and Formula 1 Hybrid Reactive coverstock — enhanced by Cohesion additives — the Rally strikes a balance between hook potential and lane adaptability. Whether you're facing medium or heavy oil patterns, it grips when you need it and drives through the pins with authority.

With its 2000 Grit finish and high differential, the Rally reads early, revs strong, and flares 4–5 inches — giving competitive bowlers a predictable motion that hits hard and stays consistent across transitions. The bold swirl of royal blue, lime, and silver commands attention on the approach, making a visual and physical impact.
