Fitting just below the Zen 25, the Ember utilizes the same ALL NEW Magna A.I. Core as the Cove. The difference is the cover. RB 82 is an aggressive pearl cover that’s designed to give you more backend while sacrificing very little traction in the oil. The Magna A.I. Core helps keep the Ember on-line and will be sure to balance out predictability and backend performance.
