ROTOR ALDHU Road Crankset
The ROTOR ALDHU Road Crankset is CNC machined out of 7075-aeronautic grade aluminum to offer unmatched rigidity while keeping weight low. Crank arm sizes start as low as 150 mm and go through 175 mm. You can also get the ALDHU in either a 24 mm or 30 mm spindle. This means you can fit the bike frame and bottom bracket of your choosing. In addition, the ALDHU can fit a wide range of ROTOR chainrings, including round, oval, 1x and 2x.
Key Product Details
Compatibility:
This crankset is compatible with both 24 mm and 30 mm bottom brackets depending on the spindle selected. This crankset can be run as a 1x or 2x and is compatible with 110×4 and 110×5 chainrings. See Compatibility tab for more information.
Standard vs. Offset Axle:
ROTOR manufactures a Standard and Offset axle that are both compatible with this crankset. For most road and gravel bikes, the standard axle provides the correct chainline. For riders using a GRX drivetrain or gravel bikes with a 50c or larger tire clearance, we recommend the Offset axle.
Key Features:
High quality aluminum construction, versatile compatibility and ROTOR INspider power meter compatible. See Specs tab for more information.
Advice From Our Staff:
Our staff recommends this crankset to road and gravel riders who are looking for a premium aluminum crankset that is both durable and versatile.
