Narrow wide chainrings for Shimano direct-mount cranks. These chainrings are designed to give the optimum chainline, which gives the smoothest shifting across the whole cassette.
These rings are direct replacements for the OEM rings: SM-CRM75 SM-CRM85 SM-CRM95
The one-piece 7075 T6 Aluminum construction is lighter than the SM-CRM75 SM-CRM85 and a similar weight to the SM-CRM95.
Shimano Chainline is determined by crank spindle length and spacers.
The chainlines with our chainrings on Shimano cranks are as follows.
