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. -OCP Only possible with Q rings Optimum Chainring Position (OCP) represents the different setup positions that ROTOR Q rings offer to fit a rider’s distinct pedaling style. Q rings feature up to 5 OCP´s, with OCP 3 as an intermediate starting point, all to optimize your pedaling style. You can determine your OCP if you know your Optimum Chainring Angle (OCA), which can be found by conducting a TORQUE 360 pedal analysis via ROTOR´s 2INpower and INpower User Software.
