Round chainrings compatible with the new ALDHU 3D+ cranks, ROTOR's lightest crankset ever, but also compatible with 4-bolt Shimano® cranks. For a perfect aesthetic integration with Shimano® cranks, there is a set of bolt covers for the different crank models.

With the ROTOR ALDHU 3D+, ROTOR has developed a future-oriented racing bike crank system, which can be freely configured and mounted without the need for special tools or specialist knowledge. Thanks to the Direct Mount System, exchanging rings is a matter of minutes when using the combination chainring in one-piece design or single rings with Direct Mount Spider one hexagon socket wrench is sufficient. Whether with round chainrings or the oval Q-rings from Rotor, everything is possible and available in many variants.
