Easton direct mount CINCH chainrings use a new narrow/wide design specifically tailored to road/cx/gravel applications. The individual teeth are tall and direction specific to create positive chain roller engagement, which is critical for chain retention over rough terrain. Extra material has been removed from the teeth to reduce running noise at the extremes of the cassette and provide excellent mud shedding characteristics.
