The new one-piece Round Direct Mount chainrings are machine CNCd from single blocks of ultralight aeronautic-grade 7075 aluminium and can be mounted straight onto the axle or crank arm. With fewer individual parts Rotor have shaved precious grams off the component weight and focused on delivering you ease of assembly and maintenance. The integrated configuration means a simplified lightweight solution without compromising on durability.
The clever spline interface between the Direct Mount and the axle delivers a robust yet smooth engagement allowing you to maximise the efficiency in transmission of power in your pedal rotation. This advanced solution is achieved thanks to the patented anchoring system of our Optimal Changing Position (OCP) Mount technology. The unique design of the teeth incorporates all the experience gained in the technological development of oval Q Rings and provides a consistently fast and precise gear shift in the most challenging of cycling conditions.
The Direct Mount is CNCd from a block of 7075 aluminum to save more than 30 g over a standard chainring combo which, together with ALDHU crank arms, becomes ROTORs lightest crankset ever. Colour: Black Anodized Number of Teeth: 34/50T Mounting: Direct OCP Mount Technologies: Alu7075, CNC, Direct Mount, OCP Mount noQ Ring Type: Inner, Outer Compatibility: ALDHU Discipline: Road Weight: 172g
