Shimano HG12 1x12 Speed Direct Mount Chainrings

Regular price $65.00

Narrow wide direct mount chainrings for Shimano direct-mount cranks. The chainring is designed to give the optimum chainline – in the middle of the cassette. This gives the smoothest shifting across the cassette and the straightest chain when in the largest or smallest cog. 

The tooth profile of our narrow/wide chainrings maintain excellent wear for a durable product and has an optimized chainline for 1x systems. 

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.
