We poured all of our experience in oval Q RINGS development into producing an innovative Round Chainrings solution. Machine CNC’d from aeronautic-grade 7055 aluminum, our new look 4-bolt chainrings are compatible with our lightweight ALDHU 3D+ crankset as well as all Shimano® 110x4 cranks.
4 bolt cranks. Combined with our new ALDHU spider and crankset, the clever spline interface between the axle delivers a robust yet smooth engagement allowing you to maximize the efficiency in transmission of power in your pedal rotation.
