North Shore Billet Shimano HG12 Variable Tooth Direct Mount Chainring

Narrow-wide 1x12 chainrings 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. The one-piece 7075 T6 Aluminum construction is lighter than the SM-CRM75 & SM-CRM85 and has a similar weight to the SM-CRM95.
