The FC-M9220 is the strongest XTR crankset ever produced. It was designed for the tough conditions of the Enduro World Series. The HOLLOWTECH II forging and a thicker steel spindle ensure that this crank can withstand even the hardest impacts while optimizing stiffness and weight. The FC-M9220 is available in lengths from 160-175 mm and can be directly mounted with all sizes of the reinforced SM-CR96 chainring, providing a specification for every enduro rider.
