SM-CRM81 CHAINRING 30T XT for FC-M8000-1
If 2X makes more sense for your riding, Shimano has you covered. The Shimano M8000 2X Chainring 34T is intended to bolt up next to Shimano's 24T inner ring.
Shimano's steel/GFRP construction does more than just look cool. The two-piece build makes for a stiffer chainring with better chain retention abilities.
