I'm replacing the freehub body in a dimension 12mm hub and I have the option of using a freehub body with either 3 pawls or 4... does it make a difference? Both kinds will fit the hub, i just don;t know which one to get. The original freehub body had 3 pawls, but they all wore down so much that they wouldnt engage and I couldnt pedal. Anyways, enlighten me!
