Oval chainrings compatible with the new ALDHU 3D+ cranks, ROTOR's lightest crankset ever, but also compatible with 4-bolt Shimano cranks. When mounted to ROTOR's ALDHU 3D+ cranks, these Q rings can be adjusted in 1-degree increments. When mounted to Shimano cranks, the chainrings are set to intermediate position OCP #3, which is the position most frequently used by road riders. For a perfect aesthetic integration with Shimano cranks, there is a set of bolt covers for the different crank models.
