This particular point is of interest to me. I believe prevailing wisdom is incorrect. Prevailing wisdom is that PressFit was a nightmare and many manufacturers went back to threaded to reduce warranty claims expense. This is true. However, the cause was that carbon-epoxy manufacturing did not materialize within spec'ed tolerances and so it was simply easier - not better - to switch to threaded to avoid resolving carbon-expoxy cure shrinkage and distortion. However, with a Ti frame, this cylinder is bored out perfectly round and perfectly sized so therefore the cause of the noise around pressfit would be eradicated. Further, there appears to be an advantage in pressfit - and Canyon and others are staying with it still while Specd has reverted to threaded - both in weight and in engineering. Apparently all bearings are pressfit and its just that BSA attaches these to the outside via threads but this is not as elegant as an inline internal bearing design. I'd like to hear intelligent and informed points around these facts.
