These OMF-equipped Dick Cepek DC-1 wheels are usually called on for trail duty, so we used Monster Valves on the DC-1s. Note the way that the OMF reinforcing ring shields the Monster Valve from trail debris. Before choosing our final installation spot, we made sure we had proper access for the Monster Chuck. Also note that the DC-1’s design let us install the Monster Valve right in the wheel’s drop center. This is an ideal location that’s far away from the wheel’s edge and the tire’s bead bundle.
