Introducing the ALDHU® cranks, ROTOR’s lightest cranks ever. The innovative modular structure, together with axles and different chainring options, makes each component individually available to accommodate the current spectrum of riders and bike standards.
The ALDHU® incorporates OCP Mount technology, which enables the rider to fine-tune the orientation of ROTOR’s oval Q RINGS. The ALDHU® proprietary, patent-pending design is based on the modularity of each crankset component.
Our new model 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.
A 30mm axle make the crankset stiffer and lighter. A low Qfactor of 140mm ensure a perfect position in the bicycle for TRACK and Fixed users.
Given the unique requirements of track cycling and fixie riding, you need a super stiff chainring able to respond to your fast-twitch muscle action and high power outputs. Aero, stiff, and crafted especially for track, our Round rings with 144BCD and designed to work with a 1/8" chain width for your track or fixed-gear bike provide the performance benefits inherent in round rings with the dependability you should expect from your chainrings.
