Rotor Round Ring Direct OCP Mount 34/50T

Constructed from grade 7075 aluminum, this component seamlessly attaches directly to the axle or crank arm. By minimizing individual components, Rotor has successfully reduced the overall weight, prioritizing effortless assembly and maintenance. The integrated design not only offers a lightweight solution but also maintains durability. The spline interface between the Direct Mount and the axle ensures a sturdy yet smooth engagement, optimizing power transmission during pedal rotation. This innovative solution is made possible by the patented anchoring system of the Optimal Changing Position (OCP) Mount technology. Drawing on expertise from the development of oval Q Rings, the unique tooth design ensures swift and precise gear shifts even in challenging cycling conditions. The Direct Mount, precision-machined from a solid block of 7075 aluminum, achieves a weight savings of over 30 g compared to a standard chainring combo. When paired with ALDHU crank arms, it becomes ROTOR's lightest crankset to date.
