ROTOR Direct Mount Round Ring NoQ chainring 53/39t

DM ROUND RING 53/39 BLACK FEATURES: - BCD: NO - QRING TYPE: Inner, Outer - COMPATIBILITY: ALDHU - DISCIPLINE: Road TECHNOLOGIES: - ALU 7075 Why we choose aluminum 7075 aeronautic-grade aluminum alloy offers superior physical properties with which to craft components like our signature Q-Rings, REX 3 and 3D24 cranks. - ALU CNC Manufactured with the latest technology Computer Numerical Control (CNC) machining provides a precise and consistent manufacturing process. This is especially important when it comes to crafting bike components in order to ensure flawless funcionality with respect to all the parts working together. Equipped with the latest CNC resources, ROTOR parts are precisely machined to within a hundredth of a millimeter. -DIRECT MOUNT The shape of the axle lets you position independently both cranks and spider or Direct Mount, and thereby change the relative orientation in order to adapt to the optimum orientation of each user. -OCP MOUNT ROTOR’s exclusive patented technology “OCP Mount” refers to the pedalling’s biomechanical optimization when you are using Q rings or other oval chainrings; this lets you adjust the orientation between chainrings and cranks by one step degree. The shape of the axle lets you position independently both cranks and spider or Direct Mount, and thereby change the relative orientation in order to adapt to the optimum orientation of each user. The multiple positions offered by “OCP Mount” technology let a fine adjustment of the OCP (Optimum Chainring Position), because so far you could position the Q rings in 5 exclusive OCP points, in 4 by 4 degrees, with a usual spider. In this way, with the OCP Mount technology, any oval chainring can benefit from an OCP with micro-adjustment to increase the performance of your pedalling and your knees health, or even to modulate the traction in MTB and Cyclo-cross. Adjust perfectly your chainrings to your pedalling style with the ROTOR’s “OCP Mount”.
