Rotor ALDHU Crank Arms Crank Arm Length:150mm Since the Raglan cut was

Since the Raglan cut was introduced to cycling jerseys by the 1986 PDM team more for logo visibility than aero efficiency

The bearing seals are dual lip

Note: Sold in sets of inner/outer chainrings

Painstaking care has been applied to every single detail - both in the design phase and in the product manufacturing process

Rotor ALDHU Crank Arms Crank Arm Length:150mm Since the Raglan cut wasIntroducing the ALDHU cranks, ROTORs 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 ROTORs oval Q RINGS. The ALDHU proprietary, patent pending design is based on the modularity of
