They're the same crank , different logos.
Riv calls it the XD2 because they take the arms(crown logo) only and put on Sugino basic rings(no ramps or pins), and sell it as a crankset. The XD600 is a stock complete crank(Sugino logo), with ramped and pinned Sugino rings. I'm not sure of the designation meaning of the 600 , as they also sell it as a 500(crown logo) and a 300(steel 36t ring) . -- You received this message because you are subscribed to the Google Groups "RBW Owners Bunch" group.
