AMF uses a numeric rating system designed to differentiate our coverstock strengths. F10 least aggressive - F90 most aggressive. Note: Core dynamics must be taken into account with shell strength when selecting equipment.


A Pure Adrenaline rush is what you'll feel when you throw this backend cornering machine. The Pure Adrenaline takes the Combustion core used in the original Pure and wraps it with a Pearl F74 coverstock. The Pure Adrenaline is the perfect compliment to the original Pure, which was designed for heavy oil. The Pure Adrenaline produces a cleaner motion through the heads, with a stronger move at the breakpoint on medium oily lanes.
