I have had a lot of advice about the relative merits of Press Fit BB30 vs a standard threaded bb, but that's not what this thread is about. The decision to go Press Fit 30 is made.
As I said. For better or for worse, I am going for Press Fit 30. I did a lot of pros and cons weighing up before I pushed the button. I just wondered whether to go for the Cannondale Hollowgram, or standard Super Record Ti.
It would appear that the Super Record Ti option is better because the cups not the bearings themselves press into the shell, eliminating a potential source of movement and therefore noise. The bearings spin in the cups, not in the frame. The cups in a Press Fit 30 are thicker and fixed, whereas the bearing races in a BB30 are thinner, and more inherently flexible since they are really only there to encase the bearings and rely on the frame's bb shell for rigidity. The Press Fit 30 cups provide this rigidity themselves.
In theory, there is no wear on the Campagnolo Press Fit 30 cups, so they won't need to be removed and reseated as often as BB30 bearings, which must lead to some sloppiness over time.
Think it will be Super Record Ti for me then. Also looks better IMHO, and there isn't that much of a weight difference.
