In another thread I mentioned that I was looking at the Cristallo or E1 to replace a noodly 585, since they are reputed to be stiffer frames. However, I have been thinking also about a compact c-50. How stiff is the C-50 compared to other frames? Any idea how it compares in stiffness to a Trek OCLV120? I have the Trek and find it far stiffer than my Look, and more secure on descents, and I am looking for something at least as stable and comfortable. Is the softness of the C-50's ride derived in part from some flex in the frame?
