The AKA is Vittoria’s high-performance XC race tire. The low-profile tread is directional to provide plenty of grip with very little rolling resistance. Wide spacing between the lugs sheds mud and loose dirt quickly to keep the tire functioning as efficiently as possible. Low-profile, aggressive corner lugs provide sharp predictable handling. We prefer this tire for the rear unless we are sure we’ll be riding smooth hardpacked dirt or slickrock.
