Narrow-wide 1x12 chainring for Shimano direct-mount cranks


These chainrings are designed to give the optimum chainline, providing the smoothest shifting across the whole cassette. NSB's Shimano direct mount chainrings are direct replacements for the OEM rings: SM-CRM75, SM-CRM85, SM-CRM95. One-piece 7075 T6 Aluminum construction is lighter than SM-CRM75, SM-CRM85, and has a similar weight to the SM-CRM95.
