Rotor Aldhu Chainring 110x4 inside oval black matte

With the ROTOR ALDHU 3D+, ROTOR has developed a trend-setting road bike crank system that can be freely configured and assembled without special tools or specialist knowledge. Thanks to the Direct Mount System, the exchange of reeds is a matter of minutes when using the combination chainring in one-piece design or single reeds with Direct Mount Spider. an Allen key is enough. Whether with round chainrings or Rotor's oval Q-rings, everything is possible and available in many variants. The Direct Mount System of the Aldhu 3D+ enables for the first time the fine adjustment of oval chainrings in 1-degree steps and thus an incomparable individualisation to the personal requirements.

In the configuration of the Aldhu 3D+, several chainring combinations milled from a single block (one-piece design) are available, pushing the system weight below the magical 600 gram mark. Alternatively, the crank can also be configured with a lightweight Direct Mount Spider and two single chainrings.

The chainrings are mounted on the spider of the ALDU 3D+ and are mounted on the axle using the direct mount method without tools. To change the chainrings only a 10mm hexagon key is needed to mount and dismount the crank arm on the drive side. The ovality of the chainrings is 12.5%.
The chainrings can also be mounted on Shimano 4 arm cranks in the OCP3 position used by most riders. For optical reasons we recommend the appropriate ROTOR cover when using on Shimano©.
