A piece of the modular pie.

Marking their lightest crankset to date, the Aldhu is Rotor's fully-modular premium crankset. Offering complete control over each individual component, the Aldhu Spindle is crucial center-piece of it all. Featuring a cleverly designed spline interface when mounted to the spider or Direct Mount chainrings delivers a robust yet smooth engagement allowing you to maximise the efficiency in transmission of power in your pedal rotation.
