Product details
With the ROTOR ALDHU 3D+, ROTOR has developed a groundbreaking road bike crankset that can be freely configured and assembled without special tools or expertise. Changing chainrings is a matter of minutes thanks to the Direct Mount System when using the combined chainring in a one-piece design or with single chainrings using the Direct Mount Spider. A hex key is all that is needed. Whether with round chainrings or Rotor's oval Q-Rings, everything is possible and available in many variations. The Direct Mount System of the Aldhu 3D+ allows for the fine adjustment of oval chainrings in 1-degree increments for unparalleled customization to personal preferences. When configuring the Aldhu 3D+, several chainring combinations, machined from a single block (one-piece design), are available, keeping the system weight below the magical 600-gram mark. Alternatively, the crank can also be configured with a lightweight Direct Mount Spider and two individual chainrings. The chainrings are mounted on the spider of the ALDHU 3D+ and are attached to the axle using the Direct Mount method without tools. To change the chainrings, only a 10mm hex key is needed to mount or 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, which is used by most riders. For aesthetic reasons, we recommend using the corresponding ROTOR covers when used with Shimano.
