Shimano has introduced an 11- speed chain "Quick-link" (SM-CN900-11). It is designed with tool-free assembly in mind for quick on-the-trail repairs. For rapid assembly of multiple chains a professional assembly tool (TL-CN10) is also available.
The Japanese manufacturer is also introducing an 1×11 chain ring with thick-then-thin Dynamic Chain Engagement" and 11-46T cassette compatible with XTR or Deore XT 1×11 set ups
A statement from Shimano said: "New XTR and Deore XT 1×11 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." (That’ll be us, then.)
Dynamic Chain Engagement, or DCE, is designed to provide "superior chain retention, lower driving sound and increased durability". There’s a modified tooth profile on the CRM91 and CRM81 DCE chain rings. Steel plated teeth on the XT version provide greater durability, while strengthened aluminum teeth on the XTR version keep the weight down, claims Shimano.
The new cassette for 1×11 riders offers a 11-46T range providing optimal gear choices for Enduro riders. The "target weight" of the CS-M8000 cassette is 450g and it’s designed to work across XTR and Deore XT platforms.
