Instead of shooting plastic into the JC mould, the JC PC was designed from the ground up, with many new ideas and only the JC shape in mind. These pedals have an ingenious way of attaching the body to the spindle. There is no spindle bolt hole. The pedal splits down the center, where the two mating sides sandwich around the spindle. Joining the two sides is achieved by the pins that thread into the mating side with replaceable steel nuts. This style of build creates an ultralight plastic pedal with the durability of an alloy pedal. In addition to weight savings, the grind options are multiplied compared to the metal version.
