New XTR 1x11 speed chain rings have been developed thanks to studies with world level cross-country and trail riders in all conditions, from the dry and dusty conditions of the Americas and southern Europe to the heavy mud of winter-time northern Europe.

Shimano Dynamic Chain Engagement Technology

Efficient chain management was the goal and the new XTR chain rings do this by introducing a concept called Dynamic Chain Engagement (DCE). The modified tooth profile on the CRM81 DCE chain rings are designed to provide superior chain retention, lower driving sound and increased durability. Strengthened aluminum teeth keep the weight down.
