            Columbia 300 brings you the new Speed. We started with the successful Power Torq and set out to create a solid asymmetric motion, perfect for a first ball out of the bag or when symmetric balls like the Power Torq are too clean. The strength of the Speed comes from the all-new cover and core combination. The new Formula 1 cover uses chemistry similar to the popular ERT formulation, but our chemists used a new additive that promotes stronger adhesion throughout the entire lane. We combined the Formula 1 cover with the new super aggressive Shifter core to ensure significantly more overall hook than the Power Torq.
