Rotor Alduh set with axle, spider and bottom bracket

With the Aldhu and Vegast, Rotor has developed a racing bike crank system that can be freely configured and installed without special tools. Thanks to the Direct Mount (DM) system, changing the chainrings takes just a few minutes. Whether you want round or oval chainrings from Rotor, everything is possible and available in many variants. The Aldhu's Direct Mount system enables fine adjustment of oval chainrings in 1-degree increments, thus allowing unparalleled customization to suit your personal requirements.
