Built for the rigors of the Enduro World Series racing, FC-M9220 is the strongest XTR crankset ever produced. HOLLOWTECH II forging and a thicker steel spindle ensure this crank survives the burliest of impacts while optimizing rigidity and weight. Offered in lengths from 160-175 mm and with all sizes of the reinforced SM-CR96 direct-mount chainring, there is a specification of FC-M9220 for every enduro rider.
