Shimano Deore XT SM-CRM81 Chainrings FC-M8000 1-speed

With the M8000, Shimano has completely renewed its outstanding XT group and, as with the XTR, relies on an 11-speed drive that scores with an incredibly wide range of applications.The teeth of the SM-CRM81 single chainrings are equipped with Shimano's new Dynamic Chain Engagement (DCE) technology and provide optimum chain guidance - both in terms of guidance during crank rotation and chain retention on the chainring in rough terrain. The danger of a chain jumping down is thus further minimised. In addition, the design of the chainrings with steel and carbon-reinforced plastic takes into account the forces and loads occurring in each case and thus guarantees a long service life.

DYNAMIC CHAIN ENGAGEMENT+
SPECIAL GEAR TEETH FUNCTION
SHIMANO’s DYNAMIC CHAIN ENGAGEMENT+ is a special gear teeth profile designed for use in single-chainring configurations for XC, enduro, and trail riding. It gives more chain retention and smoother pedaling - even over bumpy terrain. Chain retention of any gear will reduce abrasion and worn out.
