Technology

Dynamic Chain Engagement
Efficient chain management was the goal and the new XT 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.
