With the ALDHU 3D+ and the VEGAST, Rotor has developed a trend-setting road bike crank system that can be freely configured and assembled without special tools and expertise.
The chainrings are mounted on the Spider and are mounted with this via Direct Mount without tools on the axle. To change the chainrings you only need a 10mm hex tool to mount/dismount the drive side crank arm.
