Narrow wide chainrings for Shimano direct-mount cranks. These chainrings are designed to provide an optimal chainline, giving the smoothest shifting across the whole cassette.
Our Shimano HG12 specific chainring tooth profile is mated with our proven narrow-wide tooth pattern to help retain the chain on the front ring during all types of riding. Utilizing the most common bolt pattern – 104mm BCD – these rings can mount to almost any crank.
