C300 Street Rally Bowling Ball

The Columbia 300 Street Rally is built for bowlers who demand more from a shiny pearl. Designed with a strong asymmetric core and enhanced with HK22C² Formula 1 Pearl, this ball features a higher concentration of friction-boosting additives—giving it a fast, decisive response at the breakpoint. The result is a shiny ball that finally brings true power and confidence to medium and even heavier oil conditions.

Where many pearls tend to slip or lose energy, the Street Rally stands out by offering a stronger midlane read and a controlled yet dynamic backend motion. Its upgraded cover formulation ensures that when it sees friction, it moves, making it an ideal choice for bowlers who want a shiny option they can trust when the pattern demands both length and punch.
