Rotor's Lightest Modular Crankarms To Date

The Aldhu Crank arms are Rotor's lightest cranks to date. Featuring an innovative modular structure, the Aldhu allows the rider to select each component individually for a perfectly tuned crank set.

In keeping with their 3D+ crankset, these crank arms are constructed out of aeronautic grade 7055 aluminum alloy and fully CNC-machined, the Aldhu provides outstanding stiffness-to-weight ratings and an impressively low weight.Incorporating Rotor's OCP Mount technology, fine tune the placement of Rotor's Q-Rings, or easily place standard round rings.

    good cranks, nothing to complain about.

    I originally purchased these because rotor is one of the only manufacturers that make 160mm cranks
