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. Whether with round chainrings or the oval Q-rings from Rotor, everything is possible and available in many variants. The Direct Mount System of the Aldhu 3D+ allows for the first time the fine adjustment of oval chainrings in 1-degree increments and thus an incomparable individualization to the personal requirements.
When configuring the Aldhu 3D+, multiple one-piece design combinations of chainrings are available and push the system weight under the magical 600-gram mark. Alternatively, the crank can also be configured with a light Direct Mount Spider and two single chainrings.
The chainrings are made of one piece and are mounted in direct mount process without tools. To change the chainrings, only a hexagon socket wrench is needed to mount/dismantle the crank arm on the drive side. Cracking due to the screw connections between spider and chainring is a thing of the past. The ovality of the chainrings is 12.5%.
