Please clear this up for me. I have read on this board that 1and11/8
is the way to go because of the weight savings. If the fork is heavier at the larger size and the headset is heavier can the headtube be made thin enough to offset this? Is the gain in stiffness really significant?

People are going to consider 1 1/8th lighter because of the fact that you can create a thinner, yet stiffer steerer in a larger diameter. I am not sure of the physics behind it, but it is the same reason that things like oversized tubed bikes are lighter. The fork is actually not heavier, because in most cases at the 1 1/8 size the steerer is going to be carbon or aluminum making it lighter. While the standard 1" steerer is most likely going to be some type of chromoly steel. I know that you can get 1" in carbon and aluminum, but it doesn't seem to be the norm.
I don't know about the gain of stiffness issue. All my bikes are 1" (including my mtn bike) so I have nothing to base an opinion on in that regard

The only real advantage is to the bike shops and the manufactures because they only need to carry one size that you cut for each bike. Probally a good idea in the long run, but if you have 1 inch don't worry about it. In fact you can adjust stem height easier with a 1 inch. I have ridden both and cannot tell any difference.
