There is simply no way it's frame flex. The Rambouillet frame is notably stiff, far more so than traditional standard-diameter 531 frames, and they don't ghost-shift when you use old timey freewheels. The ghost shifting that was driving me crazy was on an AM-series Moulton, and you may be sure, that space frame is one of the stiffest structures that ever had 2 wheels hung off of it. It's Hyperglide that's doing it. Hyperglide is designed so that the chain can and routinely does sit on two sprockets at the same time, something that will generate tremendous noise with old timey sprockets. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "RBW Owners Bunch" group.
