With the rotor Aldhu 3D+, rotor has developed a trend-setting road bike crank system, which can be freely configured and mounted without special tools and expertise. The replacement of blades is a matter of minutes thanks to the direct mount system when using the combination chainring in one-piece design or with single blades with Direct Mount Spider. One Allen key is enough. Whether with round chain rings or the oval Q rings from rotor, everything is possible and available in many variants. The direct mount system The aldhu 3D+ allows for the first time the fine adjustment oval chain rings in 1-degree increments and thus incomparable individualisation to personal requirements. In the configuration of the aldhu 3D+, several chainring combinations are available and press the system weight under the magical 600 gram brand. Alternatively, the crank can also be configured with a light Direct Mount Spider and two single chain blades. The chain rings are mounted on the spider of the aldu 3D+ and are mounted on the axle with this in the direct mount process without tools. To change the chainrings, only a 10 hexagon socket wrench is required to install/disassemble the crank arm of the drive side. The rivalry of the chain rings 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 visual reasons, we recommend the appropriate rotor cover when using Shimano.
