The newest technology from none other than the scientists at Rotor!

This updated version of the 3D Track crank begins with 3D CNC machining of top-tier 7075-aeronautic grade aluminum to ensure unmatched rigidity. The ALDHU also features a beefy new 30mm proprietary axle system that offers extremely stiff power - even more so that previous versions of the 3D Track crank.

Can be paired with any 144mm bcd track chainring of your choice (you do not need to use a Rotor chainring).

Includes arms, axle, disc spider & chainring bolts.


Rotor Track cranksets use proprietary chainring bolts. You cannot use any other brand or type.
