Rotor ALDHU 3D Track crankset
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 many track rings that have large 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!
