Oval Chainrings:

Introducing the new oval Direct Mount with OCP Mount. OCP Mount’s patent-pending, proprietary technology allows the oval Direct Mount to be adjusted in 1-degree increments for optimized pedaling biomechanics. 12.5% ovality heightens the performance advantages of oval chainrings; no other oval chainring in the growing oval chainring category offers the adjustment options plus unique ovality all aimed at improving pedaling performance.

Round Chainrings:

Introducing the new Round Direct Mount Chainrings. The Direct Mount is CNC’d from a block of 7075 aluminum to save more than 30 g over a standard chainring combo which, together with ALDHU crank arms, becomes ROTOR’s lightest crankset ever. The ALDHU 3D+'s innovative modular structure makes each component individually available to accommodate the current spectrum of riders and bike standards.
