Oval blade from Rotor for 110 BCD and 4-hole mounting.

This chainring is compatible with the new ALDHU crankset, Rotor's lightest crankset, as well as the 4-bolt Shimano crankset. When mounted on Rotor's ALDHU crankset, these rings can be adjusted to several different positions. When mounted on Shimano cranksets, the chainrings sit in the middle position, OCP3 which is the most used by road riders.

For perfect aesthetic integration with Shimano cranksets, there are bolt covers for different crank models.
