- ALU 7075 Why We Choose Aluminum The 7075 aircraft grade aluminum alloy offers superior physical properties that allow for the manufacture of components such as Q-Rings, REX 3 and 3D24 cranks.
- ALU CNC Manufactured with the latest technology Computer Numerical Control (CNC) machining provides an accurate and consistent manufacturing process. This is especially important when manufacturing bicycle components to ensure seamless functionality of all parts that work together. Equipped with the latest CNC resources, ROTOR parts are machined with precision to within one hundredth of a millimeter.
- Direct mount: The shape of the axle allows the two cranks and the spider or Direct Mount to be positioned independently, thus changing the relative orientation to suit the optimum orientation of each user.
- OCP mount: ROTOR 's exclusive patented "OCP Mount" technology refers to the biomechanical optimization of pedaling when using Q rings or other oval chainrings; it allows you to adjust the orientation between the chainrings and cranks by one degree. The shape of the axle allows you to position the cranks and spider or Direct Mount independently, and thus change the relative orientation to suit the optimal orientation of each user. The multiple positions offered by the "OCP Mount" technology allow a fine tuning of the OCP (Optimum Chainring Position), because until now it was possible to position the Q rings in 5 exclusive OCP points, in 4 by 4 degrees, with a usual spider. So, with OCP Mount technology, any oval chainring can benefit from an OCP with micro-adjustment to increase your pedaling performance and knee health, or to modulate traction in MTB and Cyclo-cross. Perfectly match your chainrings to your pedaling style with the OCP Mount from rotor.
