Narrow wide direct mount chainrings for Race Face Cinch 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.
