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).


🔧 Pro tip: The chainring bolts supplied with this crankset will not work with some track rings that have recessed front holes (like a Zen). Pick up a set of Sugino 75 or Dura Ace chainring bolts, which can thread through without bottoming out. You'll thank us!
