OCP mount, also called Optimum Chain Position, is a system that helps you position your Q rings perfectly in relation to your crank arms. Previously, the OCP system had only 3 to 5 positions, now RotoR has taken it one step further to intermediate steps with an angle of 0.25. Perfect for getting the most!
