Columbia 300 Street Rally provides more power in the shiny ball category. Built with a strong asymmetric core and enhanced with HK22C² Formula 1 Pearl, which has a higher concentration of our friction-adding additives, the Street Rally delivers a quick response at the breakpoint. This ball is designed for bowlers who want more from a shiny pearl, offering confidence on medium to heavy oil conditions with a motion that never misses the spot.
