The Rotor ALDHU® 30 Crank features ROTOR’s innovative modular construction, allowing the crank arms, bottom bracket, spider, chainrings and power meter options to be selected separately according to frame standards, drivetrain needs and riding preferences.
Made from 7055 aluminum, the ALDHU® 30 offers a strong balance of stiffness, weight and durability. Its 30mm axle system is compatible with a wide range of ROTOR bottom bracket standards, making it a flexible choice for riders who want an efficient, lightweight and precisely configured drivetrain.
The OCP Mount system allows riders to fine-tune the orientation of ROTOR oval Q RINGS. This makes it possible to adjust chainring position according to pedaling style, power delivery and personal riding feel.
The patented design concept of the ALDHU® is based on the modular nature of each crank component, giving riders more freedom to configure and upgrade individual parts. Depending on whether a standard or offset axle is used, Q factor and chainline can also be adjusted to better match the frame and drivetrain setup.
⚠️ Please note: this product price does not include chainrings, spider, power meter or bottom bracket.
⚠️ Please confirm your frame bottom bracket standard, crank length, spider and bottom bracket compatibility before ordering.
If you are building a refined, adjustable and performance-focused ROTOR drivetrain system, the ALDHU® 30 is an excellent crank option at the center of the setup.
