Description

North Shore Billet Variable Tooth Chainring Direct Mount Shimano HG12.

Narrow-wide 1×12 chainrings for Shimano direct-mount cranks. These chainrings are designed to give the optimum chain line, providing the smoothest shifting across the whole cassette.

Our 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.
