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.
