NORTH SHORE BILLET BB30 chainring

Narrow wide direct mount chainrings for SRAM 11-speed and 12-speed Eagle 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 maintains excellent wear for a durable product.
