-- Efficient chain management was the goal and the new XTR (SM-CRM91) and DEORE XT (SM-CRM81) chain rings achieve this by introducing the Dynamic Chain Engagement (DCE) concept.\n-- \n--The modified tooth profile on the CRM91 and CRM81 DCE chain rings are designed to provide superior chain retention, lower driving noise and increased durability. Steel plated teeth on the XT version provide greater durability, while strengthened aluminum teeth on the XTR chainring reduces weight.\n\nMyBicycleParts\r\nProfessional bicycle shop\r\n\nShimano Deore XT FC-M8000 Chainring 32T SM-CRM81 Narrow Wide Version 1x11 speed\n\r\nEfficient chain management was the goal and the new XTR (SM-CRM91) and DEORE XT (SM-CRM81) chain rings achieve this by introducing the Dynamic Chain Engagement (DCE) concept.\n \nThe modified tooth profile on the CRM91 and CRM81 DCE chain rings are designed to provide superior chain retention, lower driving noise and increased durability.
