ALDHU24 DM crankset

On Demand

With the Aldhu24 crank arms for 24mm axles, the specialist for high-end CNC milling technology Rotor offers a state-of-the-art and extremely variable direct mount crank system for almost any application profile in road and gravel bikes, TT and triathlon. Aldhu24 is designed for bottom brackets with Shimano Hollowtech 2 standard (BSA and PressFit).

The crank arms of the Rotor Aldhu24 are made of particularly high-quality, cold forged as well as CNC machined 7055 aluminum, which is hollow milled by means of "Trinity Drilling" of the latest generation 3-fold and impresses with high stiffness at low weight.

The Rotor Aldhu24 is delivered as a crank arm set in up to 8 (!) Lengths and can be combined with a wide selection of 1x and 2x DM chainrings (oval and round), Direct Mount Spiders for 110x4 (Shimano compatible) and 110x5, the INspider Powermeter, as well as various axles. All components can be replaced at any time, for example, when changing a bike. Thanks to the high degree of modularity, variability and compatibility, the Rotor Aldhu24 fits perfectly into existing groups of other manufacturers or is the center of the Rotor group 1x13.

The crank and chainring assembly requires only a 10 Allen wrench. Thus, the assembly / disassembly or a chainring change is child's play. And not only in 1-way systems as in Gravel gladly chosen, but now also possible with 2-way DM chainrings.

Rotor manufactures its products exclusively in Europe and almost exclusively in its own factory in Madrid. Short delivery times, an excellent spare parts supply and support round off the image of the component specialist.
