I had an SL frame and I thought that I turned it into a wet noodle because it had started shifting under pressure. I found it was because the pivots and the bushings in my rear deraileur were way worn. I replaced the rear deraileur and viola.
Also rim flex is a big contributor to percieved rim flex. . . . . errr frame flex
