I had some trouble installing the headset. With absolutely no previous experience installing integrated headsets the bearing on top of the crown race the stack height just seemed way too high even with everything installed correctly. Initially it was also bit difficult to get the lower bearing to fit the frame. After consulting the discussion forums at RoadBikeReview I was told that the headset model is fine and I was instructed to just do some more cleaning. Removing black resin residue dust with paint thinner did improve the situation and I think things look much better at the moment. At least there is no huge 3mm gap between the frame and the fork anymore.
