Sharing compatibility with Rotor ALDHU cranks and 4 bolt shimano cranks, this is a versatile chainring. When mounted to ROTOR's ALDHU cranks, these Q RINGS can be adjusted in 1-degree increments. When mounted to Shimano cranks, the chainrings are set to intermediate position OCP3, which is the position most frequently used by road riders.
