Price includes oval or round AXS 2x chainrings. This build option is specifically for use with groupsets using the SRAM AXS® flat-top chain.
ALDHU cranks and the INspider power meter were literally made for each other. Build your crankset your way; find the perfect fit for you, and the perfect fit for your bike. The ALDHU 24 uses a 24mm axle for even more compatibility options. The smaller diameter axle can help with BB90 compatibility or internal cable routing through certain BB shells.
ALDHU construction begins with the 3D+ CNC machining to ensure unmatched rigidity from spindle to chainrings so you can take control on the roughest roads. A wealth of crank-arm lengths allow you to optimize your power, while OCP Mount technology lets you further fine-tune your ride with Q rings. The ALDHU’s proprietary, patent-pending design is based on the modularity of each crankset component.
Optimum Chainring Position (OCP) Mount technology allows the rider to fine-tune the orientation of ROTOR’s oval Q Rings by shifting them one degree at a time, finding the right balance in each pedal stroke for smooth power. This enables the rider to utilize the most powerful part of their pedal stroke to propel them further and allow a touch of relief through the weakest points.
The ALDHU's name comes directly from our racing heritage. It is an abbreviation of Alpe d’Huez to commemorate ROTOR’s first iconic victory at the Tour de France with Carlos Sastre.
Chainring Compatibility: 1x chainrings are only compatible with the Eagle AXS chain, not the AXS flat-top chain.
Fitment Note: BB386 and BB86 frames may run into INspider clearance issues; please call us for compatibility before ordering and check for contact before riding.
Some frames may run into AXS derailleur clearance issues with the larger diameter 50t outer ring.
If currently running a 48t ring, ensure there is room to raise the front derailleur.
