Speed Regime offers Tour standard aerodynamics and performance regardless of swing speed, creating optimum spin separation for longer drives without compromising on feel around the greens.

Available in three models – SR1, SR2 and SR3 – Speed Regime balls match three common swing speed categories; 90mph and below (SR1), 90-105mph (SR2) and 105mph and above (SR3), allowing golfers to ‘custom fit’ an exact Speed Regime ball to deliver total performance.

The Speed Regime family also features a new, proprietary, soft cover, delivering tour-level control for the short game, plus Callaway’s trademark HEX pattern, which optimises aerodynamics by covering a greater surface area resulting in longer, more stable and penetrative ball flights.

A soft inner core reduces driver spin across the Speed Regime line for extra-long distance, while a firmer outer core helps generate increased spin from short irons and wedges, for aggressive stopping power on the green.


Speed Regime 1 is a four-piece ball, while Speed Regime 2 and 3 are five-piece balls featuring a thin outer mantle, which also helps reduce spin off the driver even further to achieve explosive distance.

RRP: £39.99 (per dozen)
